Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
Relay HTTP requests from localhost to a remote host (act as reverse HTTP proxy).
This HTTP relay properly processes also the nonstandard HTTP responses like ICY 200 OK
produced by Shoutcast or NTRIP streaming servers.
The relay works properly with hostnames, IPv4 and IPv6 addresses. IPv6 addresses can be specified with or without []
.
usage: http-relay [-h] [-n NUM_THREADS] [-b BUFFER_SIZE] [-t SIGKILL_TIMEOUT] [-s] host [port] [local_port] [local_addr]
positional arguments:
host The remote host to connect to (e.g. "cvut.cz")
port The remote host's port to connect to (e.g. 80).
local_port The local port to be used for the relay. If left out, will be the same as remote port.
local_addr Local interface (IP or hostname) to run the relay on. By default, it runs on all IPv4 interfaces (0.0.0.0).
optional arguments:
-h, --help show this help message and exit
-n NUM_THREADS, --num-threads NUM_THREADS
Number of threads servicing the incoming requests.
-b BUFFER_SIZE, --buffer-size BUFFER_SIZE
Size of the buffer used for reading responses. Generally, a larger buffer should be more efficient, but if it is too large, the local clients may time out before they receive any data.
-t SIGKILL_TIMEOUT, --sigkill-timeout SIGKILL_TIMEOUT
If specified, the relay will be sigkilled in this number of seconds.
-s, --sigkill-on-stream-stop
If True, --sigkill-timeout will not be counted when no requests are active, and during requests, each successful data transmission will reset the timeout. This can be used to detect
stale streams if you expect an application to be constantly receiving data.
This package also provides Python module http_relay
. You can start the relay as a part of your application like this:
from http_relay import run
# ...
run("0.0.0.0", 80, "cvut.cz", 80)
http-relay cvut.cz 80 8080 # redirects local port 8080 to cvut.cz:80
http-relay cvut.cz 2101 # redirects local port 2101 to cvut.cz:2101
http-relay cvut.cz 80 8080 localhost # redirects localhost:8080 to cvut.cz:80 (i.e. no external access to the 8080 port)
http-relay stream.cz 2101 -t 10 -s # redirects local port 2101 to stream.cz and kills the relay after 10 secs if a stream is being downloaded and becomes stale
