aiowebdav 0.1.0rc5

Description:

aiowebdav 0.1.0rc5

aiowebdav





Package aiowebdav based on https://github.com/designerror/webdav-client-python but uses aiohttp instead of requests.
It provides easy way to work with WebDAV-servers.
Installation
$ pip install aiowebdav

Sample Usage
import asyncio
from aiowebdav.client import Client

options = {
'webdav_hostname': "https://webdav.server.ru",
'webdav_login': "login",
'webdav_password': "password",
"disable_check": True
}

async def main():
client = Client(options)
client.verify = False # To not check SSL certificates (Default = True)
client.execute_request("mkdir", 'directory_name')
asyncio.run(main())

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 aiowebdav.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 aiowebdav.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 aiowebdav.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 aiowebdav.client import Client

options = {
'webdav_hostname': "https://webdav.server.ru",
'webdav_login': "w_login",
'webdav_password': "w_password",
'webdav_proxy': "http://127.0.0.1:8080",
'webdav_proxy_auth': "xxx",
}
client = Client(options)

If you want to use the certificate path to certificate and private key is defined as follows:
from aiowebdav.client import Client

options = {
'webdav_hostname': "https://webdav.server.ru",
'webdav_login': "w_login",
'webdav_password': "w_password",
'webdav_ssl': 'sslcontext'
}
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)

Asynchronous methods
# Checking existence of the resource

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

# Get information about the resource

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

# Check free space

free_size = await client.free()

# Get a list of resources

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

# Create directory

await client.mkdir("dir1/dir2")

# Delete resource

await client.clean("dir1/dir2")

# Copy resource

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

# Move resource

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

# Download a resource

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

# Upload resource

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

# Publish the resource

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

# Unpublish resource

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

# Exception handling

from aiowebdav.exceptions import WebDavException

try:
...
except WebDavException as exception:
...

# Get the missing files

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

# Send missing files

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

# 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

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

For Contributors
