webdavclient3

Python WebDAV Client 3

Package webdavclient3 based on https://github.com/designerror/webdav-client-python but uses requests instead of PyCURL. It provides easy way to work with WebDAV-servers.

Installation

$ pip install webdavclient3

Sample Usage

from webdav3.client import Client
options = {
 'webdav_hostname': "https://webdav.server.ru",
 'webdav_login':    "login",
 'webdav_password': "password"
}
client = Client(options)
client.verify = False # To not check SSL certificates (Default = True)
client.session.proxies(...) # To set proxy directly into the session (Optional)
client.session.auth(...) # To set proxy auth directly into the session (Optional)
client.execute_request("mkdir", 'directory_name')

Webdav API

Webdav API is a set of webdav actions of work with cloud storage. This set includes the following actions: check, free, info, list, mkdir, clean, copy, move, download, upload, publish and unpublish.

Configuring the client

Required key is host name or IP address of the WevDAV-server with param name webdav_hostname.
For authentication in WebDAV server use webdav_login, webdav_password.
For an anonymous login do not specify auth properties.

from webdav3.client import Client

options = {
 'webdav_hostname': "https://webdav.server.ru",
 'webdav_login':    "login",
 'webdav_password': "password"
}
client = Client(options)

If your server does not support HEAD method or there are other reasons to override default WebDAV methods for actions use a dictionary option webdav_override_methods. The key should be in the following list: check, free, info, list, mkdir, clean, copy, move, download, upload, publish and unpublish. The value should a string name of WebDAV method, for example GET.

from webdav3.client import Client

options = {
 'webdav_hostname': "https://webdav.server.ru",
 'webdav_login':    "login",
 'webdav_password': "password",
 'webdav_override_methods': {
            'check': 'GET'
        }

}
client = Client(options)

For configuring a requests timeout you can use an option webdav_timeout with int value in seconds, by default the timeout is set to 30 seconds.

from webdav3.client import Client

options = {
 'webdav_hostname': "https://webdav.server.ru",
 'webdav_login':    "login",
 'webdav_password': "password",
 'webdav_timeout': 30
}
client = Client(options)

When a proxy server you need to specify settings to connect through it.

from webdav3.client import Client
options = {
 'webdav_hostname': "https://webdav.server.ru",
 'webdav_login':    "w_login",
 'webdav_password': "w_password", 
 'proxy_hostname':  "http://127.0.0.1:8080",
 'proxy_login':     "p_login",
 'proxy_password':  "p_password"
}
client = Client(options)

If you want to use the certificate path to certificate and private key is defined as follows:

from webdav3.client import Client
options = {
 'webdav_hostname': "https://webdav.server.ru",
 'webdav_login':    "w_login",
 'webdav_password': "w_password",
 'cert_path':       "/etc/ssl/certs/certificate.crt",
 'key_path':        "/etc/ssl/private/certificate.key"
}
client = Client(options)

Or you want to limit the speed or turn on verbose mode:

options = {
 ...
 'recv_speed' : 3000000,
 'send_speed' : 3000000,
 'verbose'    : True
}
client = Client(options)

recv_speed: rate limit data download speed in Bytes per second. Defaults to unlimited speed.
send_speed: rate limit data upload speed in Bytes per second. Defaults to unlimited speed.
verbose: set verbose mode on/off. By default verbose mode is off.

Also if your server does not support check it is possible to disable it:

options = {
 ...
 'disable_check': True
}
client = Client(options)

By default, checking of remote resources is enabled.

For configuring chunk size of content downloading use chunk_size param, by default it is 65536

options = {
 ...
 'chunk_size': 65536
}
client = Client(options)

Synchronous methods

# Checking existence of the resource

client.check("dir1/file1")
client.check("dir1")

# Get information about the resource

client.info("dir1/file1")
client.info("dir1/")

# Check free space

free_size = client.free()

# Get a list of resources

files1 = client.list()
files2 = client.list("dir1")
files3 = client.list("dir1", get_info=True) # returns a list of dictionaries with files details

# Create directory

client.mkdir("dir1/dir2")

# Delete resource

client.clean("dir1/dir2")

# Copy resource

client.copy(remote_path_from="dir1/file1", remote_path_to="dir2/file1")
client.copy(remote_path_from="dir2", remote_path_to="dir3")

# Move resource

client.move(remote_path_from="dir1/file1", remote_path_to="dir2/file1")
client.move(remote_path_from="dir2", remote_path_to="dir3")

# Download a resource

client.download_sync(remote_path="dir1/file1", local_path="~/Downloads/file1")
client.download_sync(remote_path="dir1/dir2/", local_path="~/Downloads/dir2/")

# Upload resource

client.upload_sync(remote_path="dir1/file1", local_path="~/Documents/file1")
client.upload_sync(remote_path="dir1/dir2/", local_path="~/Documents/dir2/")

# Publish the resource

link = client.publish("dir1/file1")
link = client.publish("dir2")

# Unpublish resource

client.unpublish("dir1/file1")
client.unpublish("dir2")

# Exception handling

from webdav3.client import WebDavException
try:
...
except WebDavException as exception:
...

# Get the missing files

client.pull(remote_directory='dir1', local_directory='~/Documents/dir1')

# Send missing files

client.push(remote_directory='dir1', local_directory='~/Documents/dir1')

Asynchronous methods

# Load resource

kwargs = {
 'remote_path': "dir1/file1",
 'local_path':  "~/Downloads/file1",
 'callback':    callback
}
client.download_async(**kwargs)

kwargs = {
 'remote_path': "dir1/dir2/",
 'local_path':  "~/Downloads/dir2/",
 'callback':    callback
}
client.download_async(**kwargs)

# Unload resource

kwargs = {
 'remote_path': "dir1/file1",
 'local_path':  "~/Downloads/file1",
 'callback':    callback
}
client.upload_async(**kwargs)

kwargs = {
 'remote_path': "dir1/dir2/",
 'local_path':  "~/Downloads/dir2/",
 'callback':    callback
}
client.upload_async(**kwargs)

Resource API

Resource API using the concept of OOP that enables cloud-level resources.

# Get a resource

res1 = client.resource("dir1/file1")

# Work with the resource

res1.rename("file2")
res1.move("dir1/file2")
res1.copy("dir2/file1")
info = res1.info()
res1.read_from(buffer)
res1.read(local_path="~/Documents/file1")
res1.read_async(local_path="~/Documents/file1", callback)
res1.write_to(buffer)
res1.write(local_path="~/Downloads/file1")
res1.write_async(local_path="~/Downloads/file1", callback)
