URL Parsing

github.com/gcherencey/gosnowflake

Package gosnowflake is a pure Go Snowflake driver for the database/sql package. Clients can use the database/sql package directly. For example: Use Open to create a database handle with connection parameters: The Go Snowflake Driver supports the following connection syntaxes (or data source name formats): where all parameters must be escaped or use `Config` and `DSN` to construct a DSN string. The following example opens a database handle with the Snowflake account myaccount where the username is jsmith, password is mypassword, database is mydb, schema is testschema, and warehouse is mywh: The following connection parameters are supported: account <string>: Specifies the name of your Snowflake account, where string is the name assigned to your account by Snowflake. In the URL you received from Snowflake, your account name is the first segment in the domain (e.g. abc123 in https://abc123.snowflakecomputing.com). This parameter is optional if your account is specified after the @ character. If you are not on us-west-2 region or AWS deployment, then append the region after the account name, e.g. “<account>.<region>”. If you are not on AWS deployment, then append not only the region, but also the platform, e.g., “<account>.<region>.<platform>”. Account, region, and platform should be separated by a period (“.”), as shown above. If you are using a global url, then append connection group and "global", e.g., "account-<connection_group>.global". Account and connection group are separated by a dash ("-"), as shown above. region <string>: DEPRECATED. You may specify a region, such as “eu-central-1”, with this parameter. However, since this parameter is deprecated, it is best to specify the region as part of the account parameter. For details, see the description of the account parameter. database: Specifies the database to use by default in the client session (can be changed after login). schema: Specifies the database schema to use by default in the client session (can be changed after login). warehouse: Specifies the virtual warehouse to use by default for queries, loading, etc. in the client session (can be changed after login). role: Specifies the role to use by default for accessing Snowflake objects in the client session (can be changed after login). passcode: Specifies the passcode provided by Duo when using MFA for login. passcodeInPassword: false by default. Set to true if the MFA passcode is embedded in the login password. Appends the MFA passcode to the end of the password. loginTimeout: Specifies the timeout, in seconds, for login. The default is 60 seconds. The login request gives up after the timeout length if the HTTP response is success. authenticator: Specifies the authenticator to use for authenticating user credentials: To use the internal Snowflake authenticator, specify snowflake (Default). To authenticate through Okta, specify https://<okta_account_name>.okta.com (URL prefix for Okta). To authenticate using your IDP via a browser, specify externalbrowser. To authenticate via OAuth, specify oauth and provide an OAuth Access Token (see the token parameter below). application: Identifies your application to Snowflake Support. insecureMode: false by default. Set to true to bypass the Online Certificate Status Protocol (OCSP) certificate revocation check. IMPORTANT: Change the default value for testing or emergency situations only. token: a token that can be used to authenticate. Should be used in conjunction with the "oauth" authenticator. client_session_keep_alive: Set to true have a heartbeat in the background every hour to keep the connection alive such that the connection session will never expire. Care should be taken in using this option as it opens up the access forever as long as the process is alive. ocspFailOpen: true by default. Set to false to make OCSP check fail closed mode. validateDefaultParameters: true by default. Set to false to disable checks on existence and privileges check for Database, Schema, Warehouse and Role when setting up the connection All other parameters are taken as session parameters. For example, TIMESTAMP_OUTPUT_FORMAT session parameter can be set by adding: The Go Snowflake Driver honors the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY for the forward proxy setting. NO_PROXY specifies which hostname endings should be allowed to bypass the proxy server, e.g. :code:`no_proxy=.amazonaws.com` means that AWS S3 access does not need to go through the proxy. NO_PROXY does not support wildcards. Each value specified should be one of the following: The end of a hostname (or a complete hostname), for example: ".amazonaws.com" or "xy12345.snowflakecomputing.com". An IP address, for example "192.196.1.15". If more than one value is specified, values should be separated by commas, for example: By default, the driver's builtin logger is NOP; no output is generated. This is intentional for those applications that use the same set of logger parameters not to conflict with glog, which is incorporated in the driver logging framework. In order to enable debug logging for the driver, add a build tag sfdebug to the go tool command lines, for example: For tests, run the test command with the tag along with glog parameters. For example, the following command will generate all acitivty logs in the standard error. Likewise, if you build your application with the tag, you may specify the same set of glog parameters. To get the logs for a specific module, use the -vmodule option. For example, to retrieve the driver.go and connection.go module logs: Note: If your request retrieves no logs, call db.Close() or glog.flush() to flush the glog buffer. Note: The logger may be changed in the future for better logging. Currently if the applications use the same parameters as glog, you cannot collect both application and driver logs at the same time. From 0.5.0, a signal handling responsibility has moved to the applications. If you want to cancel a query/command by Ctrl+C, add a os.Interrupt trap in context to execute methods that can take the context parameter, e.g., QueryContext, ExecContext. See cmd/selectmany.go for the full example. Queries return SQL column type information in the ColumnType type. The DatabaseTypeName method returns the following strings representing Snowflake data types: Go's database/sql package limits Go's data types to the following for binding and fetching: Fetching data isn't an issue since the database data type is provided along with the data so the Go Snowflake Driver can translate Snowflake data types to Go native data types. When the client binds data to send to the server, however, the driver cannot determine the date/timestamp data types to associate with binding parameters. For example: To resolve this issue, a binding parameter flag is introduced that associates any subsequent time.Time type to the DATE, TIME, TIMESTAMP_LTZ, TIMESTAMP_NTZ or BINARY data type. The above example could be rewritten as follows: The driver fetches TIMESTAMP_TZ (timestamp with time zone) data using the offset-based Location types, which represent a collection of time offsets in use in a geographical area, such as CET (Central European Time) or UTC (Coordinated Universal Time). The offset-based Location data is generated and cached when a Go Snowflake Driver application starts, and if the given offset is not in the cache, it is generated dynamically. Currently, Snowflake doesn't support the name-based Location types, e.g., America/Los_Angeles. For more information about Location types, see the Go documentation for https://golang.org/pkg/time/#Location. Internally, this feature leverages the []byte data type. As a result, BINARY data cannot be bound without the binding parameter flag. In the following example, sf is an alias for the gosnowflake package: The driver directly downloads a result set from the cloud storage if the size is large. It is required to shift workloads from the Snowflake database to the clients for scale. The download takes place by goroutine named "Chunk Downloader" asynchronously so that the driver can fetch the next result set while the application can consume the current result set. The application may change the number of result set chunk downloader if required. Note this doesn't help reduce memory footprint by itself. Consider Custom JSON Decoder. Experimental: Custom JSON Decoder for parsing Result Set The application may have the driver use a custom JSON decoder that incrementally parses the result set as follows. This option will reduce the memory footprint to half or even quarter, but it can significantly degrade the performance depending on the environment. The test cases running on Travis Ubuntu box show five times less memory footprint while four times slower. Be cautious when using the option. (Private Preview) JWT authentication ** Not recommended for production use until GA Now JWT token is supported when compiling with a golang version of 1.10 or higher. Binary compiled with lower version of golang would return an error at runtime when users try to use JWT authentication feature. To enable this feature, one can construct DSN with fields "authenticator=SNOWFLAKE_JWT&privateKey=<your_private_key>", or using Config structure specifying: The <your_private_key> should be a base64 URL encoded PKCS8 rsa private key string. One way to encode a byte slice to URL base 64 URL format is through base64.URLEncoding.EncodeToString() function. On the server side, one can alter the public key with the SQL command: The <your_public_key> should be a base64 Standard encoded PKI public key string. One way to encode a byte slice to base 64 Standard format is through base64.StdEncoding.EncodeToString() function. To generate the valid key pair, one can do the following command on the shell script: GET and PUT operations are unsupported.

github.com/tmrwh/mux

Package mux implements a request router and dispatcher. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: Let's start registering a couple of URL paths and handlers: Here we register three routes mapping URL paths to handlers. This is equivalent to how http.HandleFunc() works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (http.ResponseWriter, *http.Request) as parameters. Paths can have variables. They are defined using the format {name} or {name:pattern}. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: The names are used to create a map of route variables which can be retrieved calling mux.Vars(): Note that if any capturing groups are present, mux will panic() during parsing. To prevent this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to "/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably when capturing groups were present. And this is all you need to know about the basic usage. More advanced options are explained below. Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: There are several other matchers that can be added. To match path prefixes: ...or HTTP methods: ...or URL schemes: ...or header values: ...or query values: ...or to use a custom matcher function: ...and finally, it is possible to combine several matchers in a single route: Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". For example, let's say we have several URLs that should only match when the host is "www.example.com". Create a route for that host and get a "subrouter" from it: Then register routes in the subrouter: The three URL paths we registered above will only be tested if the domain is "www.example.com", because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths: Note that the path provided to PathPrefix() represents a "wildcard": calling PathPrefix("/static/").Handler(...) means that the handler will be passed any request that matches "/static/*". This makes it easy to serve static files with mux: Now let's see how to build registered URLs. Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling Name() on a route. For example: To build a URL, get the route and call the URL() method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: ...and the result will be a url.URL with the following path: This also works for host and query value variables: All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match. Regex support also exists for matching Headers within a route. For example, we could do: ...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` There's also a way to build only the URL host or path for a route: use the methods URLHost() or URLPath() instead. For the previous route, we would do: And if you use subrouters, host and path defined separately can be built as well: Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking. Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created). A very basic middleware which logs the URI of the request being handled could be written as: Middlewares can be added to a router using `Router.Use()`: A more complex authentication middleware, which maps session token to users, could be written as: Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

github.com/seefan/template

Package template (html/template) implements data-driven templates for generating HTML output safe against code injection. It provides the same interface as package text/template and should be used instead of text/template whenever the output is HTML. The documentation here focuses on the security features of the package. For information about how to program the templates themselves, see the documentation for text/template. This package wraps package text/template so you can share its template API to parse and execute HTML templates safely. If successful, tmpl will now be injection-safe. Otherwise, err is an error defined in the docs for ErrorCode. HTML templates treat data values as plain text which should be encoded so they can be safely embedded in an HTML document. The escaping is contextual, so actions can appear within JavaScript, CSS, and URI contexts. The security model used by this package assumes that template authors are trusted, while Execute's data parameter is not. More details are provided below. Example produces but the contextual autoescaping in html/template produces safe, escaped HTML output This package understands HTML, CSS, JavaScript, and URIs. It adds sanitizing functions to each simple action pipeline, so given the excerpt At parse time each {{.}} is overwritten to add escaping functions as necessary. In this case it becomes See the documentation of ErrorCode for details. The rest of this package comment may be skipped on first reading; it includes details necessary to understand escaping contexts and error messages. Most users will not need to understand these details. Assuming {{.}} is `O'Reilly: How are <i>you</i>?`, the table below shows how {{.}} appears when used in the context to the left. If used in an unsafe context, then the value might be filtered out: since "O'Reilly:" is not an allowed protocol like "http:". If {{.}} is the innocuous word, `left`, then it can appear more widely, Non-string values can be used in JavaScript contexts. If {{.}} is in the escaped template then the template output is See package json to understand how non-string content is marshalled for embedding in JavaScript contexts. By default, this package assumes that all pipelines produce a plain text string. It adds escaping pipeline stages necessary to correctly and safely embed that plain text string in the appropriate context. When a data value is not plain text, you can make sure it is not over-escaped by marking it with its type. Types HTML, JS, URL, and others from content.go can carry safe content that is exempted from escaping. The template can be invoked with to produce instead of the that would have been produced if {{.}} was a regular string. http://js-quasis-libraries-and-repl.googlecode.com/svn/trunk/safetemplate.html#problem_definition defines "safe" as used by this package. This package assumes that template authors are trusted, that Execute's data parameter is not, and seeks to preserve the properties below in the face of untrusted data: Structure Preservation Property: "... when a template author writes an HTML tag in a safe templating language, the browser will interpret the corresponding portion of the output as a tag regardless of the values of untrusted data, and similarly for other structures such as attribute boundaries and JS and CSS string boundaries." Code Effect Property: "... only code specified by the template author should run as a result of injecting the template output into a page and all code specified by the template author should run as a result of the same." Least Surprise Property: "A developer (or code reviewer) familiar with HTML, CSS, and JavaScript, who knows that contextual autoescaping happens should be able to look at a {{.}} and correctly infer what sanitization happens."

github.com/as/wire9

Package wire9 provides a boilerplate protocol generator. Wire9 parses wire definitions from a go package or source file. It generates structs and methods according to the given definition. To use wire9, run the standalone command line program on a go package directory containing wire definitions. Wire Definitions: A wire definition begins with a slash comment and wire9 prefix. There is no space between the slashes and prefix. The prefix is followed by a struct name and a variadic list of fields. A field becomes the name of a struct field. Next, a [bracket-enclosed], comma-seperated list of field options: width, type, and endian. Width is a field's binary width. Its value is an integer constant, a previously-defined numeric field, or empty. Types specify a field's type. This affects the type value in the final struct field, numeric and fixed types may have empty widths. Endian specifies byte-order (LE or BE), which stand for Little-Endian and Big-Endian. Little-Endian is the default value. The width and type are interpreted one of three ways depending on other values in the field options: Width is a numeric literal A. Type is empty: If width is 1, 2, 4, or 8, type is byte, uint16, uint32, and uint64, respectively. Otherwise type is []byte. B. Type is identifier: The type represents a fixed width struct, numeric value, or slice type. The width must match the fixed types binary width or be the number of expected slice elements. Width is identifier A. Type is empty: Type is implicitly []byte. The width represents the number of bytes to expect in the slice. B. Type is identifier: The type represents a slice type. The width is the number of expected elements in the slice. Width is empty A. Type is a fixed-width struct, number, or implements the Wire interface. Examples: //wire9 Ex1A Time[8] IP[4] Port[2] n[1] //wire9 Ex1B Time[8,uint64] IP[4,uint32] Port[2,uint16] n[1,byte] //wire9 Ex2A n[1] URL[n] //wire9 Ex2B n[1] URL[n,[]byte] //wire9 Ex3A p[,image.Point] size[,int64] reply[,Ex2A] //wire9 Git index[4,,BE] ... Example: The wire definition for a two-byte length-prefixed string: Generates the following struct and (fully-implemented) methods: This example defines four common length-prefixed strings The following construction builds on the last example. The value of the four 4-byte integers set the expected number of slice elements for each corresponding length-prefixed string. Trivia: The goal of this package is to save time when implementing custom protocols, such as Microsoft RDP. The package's original purpose was to take the Plan 9 draw(3) manual page and generate Go for parsing the messages written to the data file.

This makes it easy to serve static files with mux: Now let's see how to build registered URLs. Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling Name() on a route. For example: To build a URL, get the route and call the URL() method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: ...and the result will be a url.URL with the following path: This also works for host and query value variables: All variables defined in the route are required, and their values must conform to the corresponding patterns.

Regex support also exists for matching Headers within a route. For example, we could do: ...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` There's also a way to build only the URL host or path for a route: use the methods URLHost() or URLPath() instead. For the previous route, we would do: And if you use subrouters, host and path defined separately can be built as well: Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking. Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created). A very basic middleware which logs the URI of the request being handled could be written as: Middlewares can be added to a router using `Router.Use()`: A more complex authentication middleware, which maps session token to users, could be written as: Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

github.com/esachser/mux

Package mux implements a request router and dispatcher. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: Let's start registering a couple of URL paths and handlers: Here we register three routes mapping URL paths to handlers. This is equivalent to how http.HandleFunc() works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (http.ResponseWriter, *http.Request) as parameters. Paths can have variables. They are defined using the format {name} or {name:pattern}. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: The names are used to create a map of route variables which can be retrieved calling mux.Vars(): Note that if any capturing groups are present, mux will panic() during parsing. To prevent this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to "/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably when capturing groups were present. And this is all you need to know about the basic usage. More advanced options are explained below. Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: There are several other matchers that can be added. To match path prefixes: ...or HTTP methods: ...or URL schemes: ...or header values: ...or query values: ...or to use a custom matcher function: ...and finally, it is possible to combine several matchers in a single route: Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". For example, let's say we have several URLs that should only match when the host is "www.example.com". Create a route for that host and get a "subrouter" from it: Then register routes in the subrouter: The three URL paths we registered above will only be tested if the domain is "www.example.com", because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. There's one more thing about subroutes.

github.com/hIMEI29A/gichidan

Description Package gichidan is a console utility that is a wrapper for the Ichidan deep-web search engine. The purpose of the application is to collect information about hosts in Tor Network, e.g. in .onion zone. A little information about Ichidan. The search engine is less like Google and more like Shodan, in that it allows users to see technical information about .onion websites, including softwares names, services details, used protocols, connected network interfaces, such as TCP/IP ports. As Ichidan is located in .onion zone too, Gichidan uses package github.com/hIMEI29A/gotorsocks for making requests through Tor proxy. When app receives response from search engine, it asynchronously parses all results with Golang concurrency model, even if result's pagination contains a lot of web pages. Since v1.0.0 search with logical expressions is implemented. See details below. Dependencies Gichidan's CLI options are: You may search with app by keyword, by software name, by network protocol and by many others things. In most cases, Gichidan cannot search by url as main search engine cannot too. But you may try it. To get usage help, type in console: To get current app's version number (1.1.1), try To get info about same Ichidan server, type Output: To collect info about .onion sites which have "paypal" keyword in metatags, and save it to file, try: You may want to know about .onion Raspberry Pi hosts with Raspbian OS? There is many private XMPP(Jabber) servers in Tor network. To know about it, type in console: Or to collect info about Prosody XMPP servers only: To run program in non-verbose ("mute") mode, use `-m` flag. GET requests messages will not be printed in this case: To print oldschool ASCII banner before crawling start, use `-b` flag: If you don't want to see all details info about collected servers, use -s ("short") option: In case of short info and output to file mode, your file will contains all details anymore Use `-j` flag to convert output to JSON format. This feature cannot use with `-s` flag. In case `-j` and `-s` provided both there will be error. You may also save JSON to file with `-f` option. Try to search by URL: If Ichidan can not find anything by your request, application will display error: Output: Logical operators (NEW) Here is a simple rules for its usage: Expression MUST contain no more than two words (_yet_) with an operator between them and MUST NOT contain spaces between words and operator. Operators are: Examples: It will show only results which satisfy "prosody" and "ejabberd" requests both: It will show only results of "paypal" request wich not satisfy "crime" request: It will show results of "bbs" and "telnet" requests separately: If search engine cannot find anything by one of words, application will display error: Tor network may be slow. In case of long delay, restart Tor:

github.com/sfc-gh-thardie/gosnowflake

Package gosnowflake is a pure Go Snowflake driver for the database/sql package. Clients can use the database/sql package directly. For example: Use Open to create a database handle with connection parameters: The Go Snowflake Driver supports the following connection syntaxes (or data source name formats): where all parameters must be escaped or use `Config` and `DSN` to construct a DSN string. The following example opens a database handle with the Snowflake account myaccount where the username is jsmith, password is mypassword, database is mydb, schema is testschema, and warehouse is mywh: The following connection parameters are supported: account <string>: Specifies the name of your Snowflake account, where string is the name assigned to your account by Snowflake. In the URL you received from Snowflake, your account name is the first segment in the domain (e.g. abc123 in https://abc123.snowflakecomputing.com). This parameter is optional if your account is specified after the @ character. If you are not on us-west-2 region or AWS deployment, then append the region after the account name, e.g. “<account>.<region>”. If you are not on AWS deployment, then append not only the region, but also the platform, e.g., “<account>.<region>.<platform>”. Account, region, and platform should be separated by a period (“.”), as shown above. If you are using a global url, then append connection group and "global", e.g., "account-<connection_group>.global". Account and connection group are separated by a dash ("-"), as shown above. region <string>: DEPRECATED. You may specify a region, such as “eu-central-1”, with this parameter. However, since this parameter is deprecated, it is best to specify the region as part of the account parameter. For details, see the description of the account parameter. database: Specifies the database to use by default in the client session (can be changed after login). schema: Specifies the database schema to use by default in the client session (can be changed after login). warehouse: Specifies the virtual warehouse to use by default for queries, loading, etc. in the client session (can be changed after login). role: Specifies the role to use by default for accessing Snowflake objects in the client session (can be changed after login). passcode: Specifies the passcode provided by Duo when using MFA for login. passcodeInPassword: false by default. Set to true if the MFA passcode is embedded in the login password. Appends the MFA passcode to the end of the password. loginTimeout: Specifies the timeout, in seconds, for login. The default is 60 seconds. The login request gives up after the timeout length if the HTTP response is success. authenticator: Specifies the authenticator to use for authenticating user credentials: To use the internal Snowflake authenticator, specify snowflake (Default). To authenticate through Okta, specify https://<okta_account_name>.okta.com (URL prefix for Okta). To authenticate using your IDP via a browser, specify externalbrowser. To authenticate via OAuth, specify oauth and provide an OAuth Access Token (see the token parameter below). application: Identifies your application to Snowflake Support. insecureMode: false by default. Set to true to bypass the Online Certificate Status Protocol (OCSP) certificate revocation check. IMPORTANT: Change the default value for testing or emergency situations only. token: a token that can be used to authenticate. Should be used in conjunction with the "oauth" authenticator. client_session_keep_alive: Set to true have a heartbeat in the background every hour to keep the connection alive such that the connection session will never expire. Care should be taken in using this option as it opens up the access forever as long as the process is alive. ocspFailOpen: true by default. Set to false to make OCSP check fail closed mode. validateDefaultParameters: true by default. Set to false to disable checks on existence and privileges check for Database, Schema, Warehouse and Role when setting up the connection All other parameters are taken as session parameters. For example, TIMESTAMP_OUTPUT_FORMAT session parameter can be set by adding: The Go Snowflake Driver honors the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY for the forward proxy setting. NO_PROXY specifies which hostname endings should be allowed to bypass the proxy server, e.g. :code:`no_proxy=.amazonaws.com` means that AWS S3 access does not need to go through the proxy. NO_PROXY does not support wildcards. Each value specified should be one of the following: The end of a hostname (or a complete hostname), for example: ".amazonaws.com" or "xy12345.snowflakecomputing.com". An IP address, for example "192.196.1.15". If more than one value is specified, values should be separated by commas, for example: By default, the driver's builtin logger is NOP; no output is generated. This is intentional for those applications that use the same set of logger parameters not to conflict with glog, which is incorporated in the driver logging framework. In order to enable debug logging for the driver, add a build tag sfdebug to the go tool command lines, for example: For tests, run the test command with the tag along with glog parameters. For example, the following command will generate all acitivty logs in the standard error. Likewise, if you build your application with the tag, you may specify the same set of glog parameters. To get the logs for a specific module, use the -vmodule option. For example, to retrieve the driver.go and connection.go module logs: Note: If your request retrieves no logs, call db.Close() or glog.flush() to flush the glog buffer. Note: The logger may be changed in the future for better logging. Currently if the applications use the same parameters as glog, you cannot collect both application and driver logs at the same time. From 0.5.0, a signal handling responsibility has moved to the applications. If you want to cancel a query/command by Ctrl+C, add a os.Interrupt trap in context to execute methods that can take the context parameter, e.g., QueryContext, ExecContext. See cmd/selectmany.go for the full example. Queries return SQL column type information in the ColumnType type. The DatabaseTypeName method returns the following strings representing Snowflake data types: Go's database/sql package limits Go's data types to the following for binding and fetching: Fetching data isn't an issue since the database data type is provided along with the data so the Go Snowflake Driver can translate Snowflake data types to Go native data types. When the client binds data to send to the server, however, the driver cannot determine the date/timestamp data types to associate with binding parameters. For example: To resolve this issue, a binding parameter flag is introduced that associates any subsequent time.Time type to the DATE, TIME, TIMESTAMP_LTZ, TIMESTAMP_NTZ or BINARY data type. The above example could be rewritten as follows: The driver fetches TIMESTAMP_TZ (timestamp with time zone) data using the offset-based Location types, which represent a collection of time offsets in use in a geographical area, such as CET (Central European Time) or UTC (Coordinated Universal Time). The offset-based Location data is generated and cached when a Go Snowflake Driver application starts, and if the given offset is not in the cache, it is generated dynamically. Currently, Snowflake doesn't support the name-based Location types, e.g., America/Los_Angeles. For more information about Location types, see the Go documentation for https://golang.org/pkg/time/#Location. Internally, this feature leverages the []byte data type. As a result, BINARY data cannot be bound without the binding parameter flag. In the following example, sf is an alias for the gosnowflake package: The driver directly downloads a result set from the cloud storage if the size is large. It is required to shift workloads from the Snowflake database to the clients for scale. The download takes place by goroutine named "Chunk Downloader" asynchronously so that the driver can fetch the next result set while the application can consume the current result set. The application may change the number of result set chunk downloader if required. Note this doesn't help reduce memory footprint by itself. Consider Custom JSON Decoder. Experimental: Custom JSON Decoder for parsing Result Set The application may have the driver use a custom JSON decoder that incrementally parses the result set as follows. This option will reduce the memory footprint to half or even quarter, but it can significantly degrade the performance depending on the environment. The test cases running on Travis Ubuntu box show five times less memory footprint while four times slower. Be cautious when using the option. (Private Preview) JWT authentication ** Not recommended for production use until GA Now JWT token is supported when compiling with a golang version of 1.10 or higher. Binary compiled with lower version of golang would return an error at runtime when users try to use JWT authentication feature. To enable this feature, one can construct DSN with fields "authenticator=SNOWFLAKE_JWT&privateKey=<your_private_key>", or using Config structure specifying: The <your_private_key> should be a base64 URL encoded PKCS8 rsa private key string. One way to encode a byte slice to URL base 64 URL format is through base64.URLEncoding.EncodeToString() function. On the server side, one can alter the public key with the SQL command: The <your_public_key> should be a base64 Standard encoded PKI public key string. One way to encode a byte slice to base 64 Standard format is through base64.StdEncoding.EncodeToString() function. To generate the valid key pair, one can do the following command on the shell script: GET and PUT operations are unsupported.

Package mux implements a request router and dispatcher. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: Let's start registering a couple of URL paths and handlers: Here we register three routes mapping URL paths to handlers. This is equivalent to how http.HandleFunc() works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (http.ResponseWriter, *http.Request) as parameters. Paths can have variables. They are defined using the format {name} or {name:pattern}. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: The names are used to create a map of route variables which can be retrieved calling mux.Vars(): Note that if any capturing groups are present, mux will panic() during parsing. To prevent this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to "/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably when capturing groups were present. And this is all you need to know about the basic usage. More advanced options are explained below. Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: There are several other matchers that can be added. To match path prefixes: ...or HTTP methods: ...or URL schemes: ...or header values: ...or query values: ...or to use a custom matcher function: ...and finally, it is possible to combine several matchers in a single route: Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". For example, let's say we have several URLs that should only match when the host is "www.example.com". Create a route for that host and get a "subrouter" from it: Then register routes in the subrouter: The three URL paths we registered above will only be tested if the domain is "www.example.com", because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths: Note that the path provided to PathPrefix() represents a "wildcard": calling PathPrefix("/static/").Handler(...) means that the handler will be passed any request that matches "/static/*". This makes it easy to serve static files with mux: Now let's see how to build registered URLs. Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling Name() on a route. For example: To build a URL, get the route and call the URL() method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: ...and the result will be a url.URL with the following path: This also works for host and query value variables: All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match. Regex support also exists for matching Headers within a route. For example, we could do: ...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` There's also a way to build only the URL host or path for a route: use the methods URLHost() or URLPath() instead. For the previous route, we would do: And if you use subrouters, host and path defined separately can be built as well: Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking. Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created). A very basic middleware which logs the URI of the request being handled could be written as: Middlewares can be added to a router using `Router.Use()`: A more complex authentication middleware, which maps session token to users, could be written as: Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

A golang implementation of the EFF's HTTPS Anywhere This source contains exports for both _server_ and client-side use, as in, the construction of the ruleset in proprietary format and the reconstruction into memory, and actual intended URL rewrite logic The general approach is to teach a filter about the simple target hosts (no wildcard, or one wildcard at one of the endings of the pattern), this will block the vast majority of sites (with testing time well below the millisecond), complicated wildcards will be saved in a map, and transformed into a pcre regex pattern (the * token will be expanded into [^\.]+) and precompiled for speed (right now there are 22 such cases), and tried by matching the input versus the compiled regex; lastly there's a hashmap (which has indices the 32bit hash of the target string representation, values, the associated rulesets) which will load the available rules to apply, this is a filtering and retrieval logic. Upon generating the structure hash collisions are handled by evacuating the colliding entry into the forward structure. A flow of rewrite is as follows: 1. try to match input to forward map regexes 1.1 if match occurs, apply the first rule that fits (return if url is excluded), return the resulting url 2. try url in filter, if is not found (not, there is 0% false negatives) return 3. find the asociated rulesets with combinations {url, url_first_subdomain_wildcarded, url_tld_wildcarded} (Example: input = somesubdomain.example.com -> {somesubdomain.example.com, *.example.com, somesubdomain.example.*}) 3.1 if there's a match, apply the first rule that fits (return if url is excluded), and return the new url Encoding takes the structures and serializes them in a space optimized format, cuckoofilter has already an encode implemented, slice is encoded in a straightforward manner, regularMap (aka map[uint32][]int, aka hash(url)->array(of_applicable_rulesets)) needs an extra step, since the unique values are around 5K (the `int`s from all the `[]int`s), the implementation is to flip the map and try to encode a [][]uint32 where the index of the first dimension is the value from the map, and the second index is the order of occurence of the hash, and finally the uint32 values are the hashes Exported functions: Parse -- reads the rules from the given path, and constructs the appropriate structures resulting in a HtEvSt or an error Encode/EncodeToPath/Decode -- as their name suggests handles encoding and decoding of the structure, EncodeToPath flushes the compressed format to a specified file. TryRewrite -- searches for and applies the appropriate rewrite rules, returns the new url (or old one if no match occured) or an error ShowStats -- prints the statistics of the structure in memory

gitlab.com/MatteoCampinoti94/faapi-go

Package faapi uses GET requests and parsing to get metadata from the main sections of FurAffinity. These include submissions, user-pages, galleries and searches. The package loads cookies from a JSON formatted file and will return structs with the requested metadata. The main type in the package is faapi.FAAPI. The Cookies and Request fields are assigned using faapi.LoadCookies() and faapi.MakeRequest() methods. The thus assigned cookies and request will be used by the rest of the package to perform the GET requests. The Interval field specifies how long to wait between requests (i.e. throttle). The other two types are used to return parsed metadata from the requests. The field names describe their content. For Submission.ID an int type has been used instead of string because the a submission ID on FA can only be a number, the other fields use simple strings (or slices of them) for easier handling. The Submission type contains the metadata that the package can parse from the submission page. The date is the only modified field: the package converts from the "Mmm D, YYYY" format to "YYYY-MM-DD" for easier sorting and reformatting. Tags are stored in a non-sorted slice. The Description field contains the HTML source of the submission description, directly extracted from the response. The only edit the package performs is to add "http:" to src attributes that lack it (i.e. resources internal to FA). The FileURL field stores the link to the submission file (with "http:" added). The File field stores the binary data of the submission file. The User type contains the metadata extracted from a user's main page. User.Userid and User.Username store the same value but in two different formats. Userid is the url-compatible version of the username, so it lacks capital letters and the underscore character is removed. Username instead stores the user-formatted version of the name (i.e. with capital letters, underscore). The Title is the small "description" chosen by the user (e.g. Writer, Artist, etc...) and extracted as is. The Status can be active, suspended or deceased at the moment and it depends from the first character that FA automatically prefixes to the user's name (e.g. "~UserName" for an active username). Date is the date the user joined, formatted to "YYYY-MM-DD". The Profile is the HTML source of the main description written by the user. The FAAPI type supports two types of methods, one to initialize the api, the other to get data off the forum. LoadCookies() and MakeRequest() are used to initialize the type. The first takes a string as filename and opens the corresponding file. If the file is properly formatted (in JSON) then the cookies contained in it will be loaded into the api as a slice of http.Cookie. The cookies file needs to contain elements with at least name and value keys, others are not necessary. MakeRequest() simply takes the cookies slice returned and saved by LoadCookies() and uses it to create a http.Request object which is then saved in the FAAPI struct. The Get* methods return single structs or slices of what their name suggests. GetSubmission() and GetUser() return a single struct of type Submission and User respectively. These are the calls that provide the most information for both user and submission. GetGallery(), GetScraps(), GetFavorites() and GetSearch() all return a slice of Submission. Gallery, scraps and favorites take a userid as argument together with a page value. The slices returned contain normal Submission structs but with less information: the Date, Tags, Description and FileURL fields are empty. This is because these methods parse the links contained withing the user folders (or search pages) which do not contain those values. The second item the methods return is the next page in the specific section. If no next page page can be found (i.e. there is no next page button) then `next` will have value -1. For gallery, scraps and searches the next page item is just the passed page argument increased by 1, for favorites it is the id of the next page. GetFavorites() page works differently than the others. FA uses an id for favorites pages. 0 can be used to get the first page and 1 for the last, but those in between will need the specific page id. GetSearch() takes a map argument with both keys and values of type string. These are then encoded using the URL. Values method AddValues and are then encoded and added to the URL.RawQuery field of the http.Request. The Submission type supports a single method. GetFile() downloads the file pointed at by FileURL and saves its binary data into the File field.

github.com/andreiko/gosnowflake

Package gosnowflake is a pure Go Snowflake driver for the database/sql package. Clients can use the database/sql package directly. For example: Use Open to create a database handle with connection parameters: The Go Snowflake Driver supports the following connection syntaxes (or data source name formats): where all parameters must be escaped or use `Config` and `DSN` to construct a DSN string. The following example opens a database handle with the Snowflake account myaccount where the username is jsmith, password is mypassword, database is mydb, schema is testschema, and warehouse is mywh: The following connection parameters are supported: account <string>: Specifies the name of your Snowflake account, where string is the name assigned to your account by Snowflake. In the URL you received from Snowflake, your account name is the first segment in the domain (e.g. abc123 in https://abc123.snowflakecomputing.com). This parameter is optional if your account is specified after the @ character. If you are not on us-west-2 region or AWS deployment, then append the region after the account name, e.g. “<account>.<region>”. If you are not on AWS deployment, then append not only the region, but also the platform, e.g., “<account>.<region>.<platform>”. Account, region, and platform should be separated by a period (“.”), as shown above. region <string>: DEPRECATED. You may specify a region, such as “eu-central-1”, with this parameter. However, since this parameter is deprecated, it is best to specify the region as part of the account parameter. For details, see the description of the account parameter. database: Specifies the database to use by default in the client session (can be changed after login). schema: Specifies the database schema to use by default in the client session (can be changed after login). warehouse: Specifies the virtual warehouse to use by default for queries, loading, etc. in the client session (can be changed after login). role: Specifies the role to use by default for accessing Snowflake objects in the client session (can be changed after login). passcode: Specifies the passcode provided by Duo when using MFA for login. passcodeInPassword: false by default. Set to true if the MFA passcode is embedded in the login password. Appends the MFA passcode to the end of the password. loginTimeout: Specifies the timeout, in seconds, for login. The default is 60 seconds. The login request gives up after the timeout length if the HTTP response is success. authenticator: Specifies the authenticator to use for authenticating user credentials: To use the internal Snowflake authenticator, specify snowflake (Default). To authenticate through Okta, specify https://<okta_account_name>.okta.com (URL prefix for Okta). To authenticate using your IDP via a browser, specify externalbrowser. To authenticate via OAuth, specify oauth and provide an OAuth Access Token (see the token parameter below). application: Identifies your application to Snowflake Support. insecureMode false by default. Set to true to bypass the Online Certificate Status Protocol (OCSP) certificate revocation check. IMPORTANT: Change the default value for testing or emergency situations only. token: a token that can be used to authenticate. Should be used in conjunction with the "oauth" authenticator. client_session_keep_alive: Set to true have a heartbeat in the background every hour to keep the connection alive such that the connection session will never expire. Care should be taken in using this option as it opens up the access forever as long as the process is alive. All other parameters are taken as session parameters. For example, TIMESTAMP_OUTPUT_FORMAT session parameter can be set by adding: The Go Snowflake Driver honors the environment variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY for the forward proxy setting. By default, the driver's builtin logger is NOP; no output is generated. This is intentional for those applications that use the same set of logger parameters not to conflict with glog, which is incorporated in the driver logging framework. In order to enable debug logging for the driver, add a build tag sfdebug to the go tool command lines, for example: For tests, run the test command with the tag along with glog parameters. For example, the following command will generate all acitivty logs in the standard error. Likewise, if you build your application with the tag, you may specify the same set of glog parameters. To get the logs for a specific module, use the -vmodule option. For example, to retrieve the driver.go and connection.go module logs: Note: If your request retrieves no logs, call db.Close() or glog.flush() to flush the glog buffer. Note: The logger may be changed in the future for better logging. Currently if the applications use the same parameters as glog, you cannot collect both application and driver logs at the same time. From 0.5.0, a signal handling responsibility has moved to the applications. If you want to cancel a query/command by Ctrl+C, add a os.Interrupt trap in context to execute methods that can take the context parameter, e.g., QueryContext, ExecContext. See cmd/selectmany.go for the full example. Queries return SQL column type information in the ColumnType type. The DatabaseTypeName method returns the following strings representing Snowflake data types: Go's database/sql package limits Go's data types to the following for binding and fetching: Fetching data isn't an issue since the database data type is provided along with the data so the Go Snowflake Driver can translate Snowflake data types to Go native data types. When the client binds data to send to the server, however, the driver cannot determine the date/timestamp data types to associate with binding parameters. For example: To resolve this issue, a binding parameter flag is introduced that associates any subsequent time.Time type to the DATE, TIME, TIMESTAMP_LTZ, TIMESTAMP_NTZ or BINARY data type. The above example could be rewritten as follows: The driver fetches TIMESTAMP_TZ (timestamp with time zone) data using the offset-based Location types, which represent a collection of time offsets in use in a geographical area, such as CET (Central European Time) or UTC (Coordinated Universal Time). The offset-based Location data is generated and cached when a Go Snowflake Driver application starts, and if the given offset is not in the cache, it is generated dynamically. Currently, Snowflake doesn't support the name-based Location types, e.g., America/Los_Angeles. For more information about Location types, see the Go documentation for https://golang.org/pkg/time/#Location. Internally, this feature leverages the []byte data type. As a result, BINARY data cannot be bound without the binding parameter flag. In the following example, sf is an alias for the gosnowflake package: The driver directly downloads a result set from the cloud storage if the size is large. It is required to shift workloads from the Snowflake database to the clients for scale. The download takes place by goroutine named "Chunk Downloader" asynchronously so that the driver can fetch the next result set while the application can consume the current result set. The application may change the number of result set chunk downloader if required. Note this doesn't help reduce memory footprint by itself. Consider Custom JSON Decoder. Experimental: Custom JSON Decoder for parsing Result Set The application may have the driver use a custom JSON decoder that incrementally parses the result set as follows. This option will reduce the memory footprint to half or even quarter, but it can significantly degrade the performance depending on the environment. The test cases running on Travis Ubuntu box show five times less memory footprint while four times slower. Be cautious when using the option. (Private Preview) JWT authentication ** Not recommended for production use until GA Now JWT token is supported when compiling with a golang version of 1.10 or higher. Binary compiled with lower version of golang would return an error at runtime when users try to use JWT authentication feature. To enable this feature, one can construct DSN with fields "authenticator=SNOWFLAKE_JWT&privateKey=<your_private_key>", or using Config structure specifying: The <your_private_key> should be a base64 URL encoded PKCS8 rsa private key string. One way to encode a byte slice to URL base 64 URL format is through base64.URLEncoding.EncodeToString() function.

For the previous route, we would do: ...and the result will be a url.URL with the following path: This also works for host and query value variables: All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match. Regex support also exists for matching Headers within a route. For example, we could do: ...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` There's also a way to build only the URL host or path for a route: use the methods URLHost() or URLPath() instead. For the previous route, we would do: And if you use subrouters, host and path defined separately can be built as well: Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking. Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created). A very basic middleware which logs the URI of the request being handled could be written as: Middlewares can be added to a router using `Router.Use()`: A more complex authentication middleware, which maps session token to users, could be written as: Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

Package mux implements a request router and dispatcher. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: Let's start registering a couple of URL paths and handlers: Here we register three routes mapping URL paths to handlers. This is equivalent to how http.HandleFunc() works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (http.ResponseWriter, *http.Request) as parameters. Paths can have variables. They are defined using the format {name} or {name:pattern}. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: The names are used to create a map of route variables which can be retrieved calling mux.Vars(): Note that if any capturing groups are present, mux will panic() during parsing. To prevent this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to "/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably when capturing groups were present. And this is all you need to know about the basic usage. More advanced options are explained below. Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: There are several other matchers that can be added. To match path prefixes: ...or HTTP methods: ...or URL schemes: ...or header values: ...or query values: ...or to use a custom matcher function: ...and finally, it is possible to combine several matchers in a single route: Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". For example, let's say we have several URLs that should only match when the host is "www.example.com". Create a route for that host and get a "subrouter" from it: Then register routes in the subrouter: The three URL paths we registered above will only be tested if the domain is "www.example.com", because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths: Note that the path provided to PathPrefix() represents a "wildcard": calling PathPrefix("/static/").Handler(...) means that the handler will be passed any request that matches "/static/*".

This is a change from prior versions which behaved unpredictably when capturing groups were present. And this is all you need to know about the basic usage. More advanced options are explained below. Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: There are several other matchers that can be added. To match path prefixes: ...or HTTP methods: ...or URL schemes: ...or header values: ...or query values: ...or to use a custom matcher function: ...and finally, it is possible to combine several matchers in a single route: Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". For example, let's say we have several URLs that should only match when the host is "www.example.com". Create a route for that host and get a "subrouter" from it: Then register routes in the subrouter: The three URL paths we registered above will only be tested if the domain is "www.example.com", because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths: Note that the path provided to PathPrefix() represents a "wildcard": calling PathPrefix("/static/").Handler(...) means that the handler will be passed any request that matches "/static/*". This makes it easy to serve static files with mux: Now let's see how to build registered URLs. Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling Name() on a route. For example: To build a URL, get the route and call the URL() method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: ...and the result will be a url.URL with the following path: This also works for host variables: All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match. Regex support also exists for matching Headers within a route. For example, we could do: ...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` There's also a way to build only the URL host or path for a route: use the methods URLHost() or URLPath() instead. For the previous route, we would do: And if you use subrouters, host and path defined separately can be built as well:

github.com/reedobrien/goredirect

goredirect is an http server that serves redirects based on a mapping formatted in JSON. Usage: Available arguments: Rules format: The rules file should be a hash where the keys are the domains that should be forwarded and each key's value is a hash. In each hash at this level the keys are the aliases and values are a hash with target destinations under the key "location" and optionally a "reviewed" key with the last time the redirect was reviewed. Aliases should always be the full path segment to be matched -- including the slash and any query arguments. Location keys may be the absolute target *path* or a complete URL and the reviewed key is a string (I format them as RFC1123/RFC822 dates). The "location" target should almost invariably be a complete URL, but in my situation the redirects were sometimes many within a subdomain... Following is an example rules file: Use the key "default" to name a location to which all non-matching requests should be redirected. Use the key "*" to specify that all requests should be redirected to a location with the URI path and query strings intact. If a glob exists "default" will never be found. This will parse the incoming request and the location with url. Parse and update the scheme, host, and port in the request URL to generate the location to return in the redirect response. Processing in the following order: match a path: return provided location check for "*": return with base and request path + query args check for "default" and return provided location return not found { "example.com":{ "*": { "location": "http://glob.example.org/", "reviewed": "Mon, 12 Aug 2013" }, "/here": { "location": "/there/", "reviewed": "Fri, 26 Jul 2013" }, "/there/": { "location": "http://remote.example.com/eggs/" }, "/spam": { "location": "http://ou.example.com/ham/?id=s0s9d8", "reviewed": "Fri, 26 Jul 2013" } }, "ou2.example.com":{ "default": { "location": "http://example.net/default", "reviewed": "Tues, 13 Aug 2013" }, "/notdefault": { "location": "http://example.net/notdefault" }, "/baz": { "location": "http://vip.example.com/buz/", "reviewed": "Fri, 26 Jul 2013" }, "/local?id=sn4ckb4r": { "location": "http://vip.example.com/remote/", "reviewed": "Fri, 26 Jul 2013" }, "/tomorrow/": { "location": "http://www.example.com/gone" }, "/here": { "location": "http://www.example.com/today", "reviewed": "Fri, 26 Jul 2013" } }, "example.org":{ "/happy": { "location": "http://archive.example.com/hour", "reviewed": "Fri, 26 Jul 2013" }, "/koan": { "location": "https://www.example.com/riddle", "reviewed": "Fri, 26 Jul 2013" }, "/last": { "location": "/time", "reviewed": "Fri, 26 Jul 2013" }, "/time": { "location": "https://archive.example.com/?word=foo", "reviewed": "Fri, 26 Jul 2013" } } } Motivation: On a particular project we needed a simple way to manage a lot of redirects for a large number of vanity domains. For historic reasons there were a variety of domains which had been consolidated under rather fewer domains. This project was born in and in an evening...is likely done. I don't expect it to do much additional at this point.

Package mux implements a request router and dispatcher. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: Let's start registering a couple of URL paths and handlers: Here we register three routes mapping URL paths to handlers. This is equivalent to how http.HandleFunc() works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (http.ResponseWriter, *http.Request) as parameters. Paths can have variables. They are defined using the format {name} or {name:pattern}. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: The names are used to create a map of route variables which can be retrieved calling mux.Vars(): Note that if any capturing groups are present, mux will panic() during parsing. To prevent this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to "/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably when capturing groups were present. And this is all you need to know about the basic usage. More advanced options are explained below. Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: There are several other matchers that can be added. To match path prefixes: ...or HTTP methods: ...or URL schemes: ...or header values: ...or query values: ...or to use a custom matcher function: ...and finally, it is possible to combine several matchers in a single route: Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". For example, let's say we have several URLs that should only match when the host is "www.example.com". Create a route for that host and get a "subrouter" from it: Then register routes in the subrouter: The three URL paths we registered above will only be tested if the domain is "www.example.com", because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths: Note that the path provided to PathPrefix() represents a "wildcard": calling PathPrefix("/static/").Handler(...) means that the handler will be passed any request that matches "/static/*". This makes it easy to serve static files with mux: Now let's see how to build registered URLs. Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling Name() on a route. For example: To build a URL, get the route and call the URL() method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: ...and the result will be a url.URL with the following path: This also works for host variables: All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match. Regex support also exists for matching Headers within a route. For example, we could do: ...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` There's also a way to build only the URL host or path for a route: use the methods URLHost() or URLPath() instead. For the previous route, we would do: And if you use subrouters, host and path defined separately can be built as well:

github.com/tonyespy/mux

Package mux implements a request router and dispatcher. The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, mux.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: Let's start registering a couple of URL paths and handlers: Here we register three routes mapping URL paths to handlers. This is equivalent to how http.HandleFunc() works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (http.ResponseWriter, *http.Request) as parameters. Paths can have variables. They are defined using the format {name} or {name:pattern}. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: Groups can be used inside patterns, as long as they are non-capturing (?:re). For example: The names are used to create a map of route variables which can be retrieved calling mux.Vars(): Note that if any capturing groups are present, mux will panic() during parsing. To prevent this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to "/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably when capturing groups were present. And this is all you need to know about the basic usage. More advanced options are explained below. Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: There are several other matchers that can be added. To match path prefixes: ...or HTTP methods: ...or URL schemes: ...or header values: ...or query values: ...or to use a custom matcher function: ...and finally, it is possible to combine several matchers in a single route: Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements.

For the previous route, we would do: And if you use subrouters, host and path defined separately can be built as well: Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking. Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created). A very basic middleware which logs the URI of the request being handled could be written as: Middlewares can be added to a router using `Router.Use()`: A more complex authentication middleware, which maps session token to users, could be written as: Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.
