Use requests to talk HTTP via a UNIX domain socket

Project description

Latest Version on PyPI

Use requests to talk HTTP via a UNIX domain socket



You can use it by instantiating a special Session object:

import json

import requests_unixsocket

session = requests_unixsocket.Session()

r = session.get('http+unix://%2Fvar%2Frun%2Fdocker.sock/info')
registry_config = r.json()['RegistryConfig']
print(json.dumps(registry_config, indent=4))

Implicit (monkeypatching)

Monkeypatching allows you to use the functionality in this module, while making minimal changes to your code. Note that in the above example we had to instantiate a special requests_unixsocket.Session object and call the get method on that object. Calling requests.get(url) (the easiest way to use requests and probably very common), would not work. But we can make it work by doing monkeypatching.

You can monkeypatch globally:

import requests_unixsocket


r = requests.get('http+unix://%2Fvar%2Frun%2Fdocker.sock/info')
assert r.status_code == 200

or you can do it temporarily using a context manager:

import requests_unixsocket

with requests_unixsocket.monkeypatch():
    r = requests.get('http+unix://%2Fvar%2Frun%2Fdocker.sock/info')
    assert r.status_code == 200

Abstract namespace sockets

To connect to an abstract namespace socket (Linux only), prefix the name with a NULL byte (i.e.: 0) - e.g.:

import requests_unixsocket

session = requests_unixsocket.Session()
res = session.get('http+unix://\0test_socket/get')

For an example program that illustrates this, see examples/ in the git repo. Since abstract namespace sockets are specific to Linux, the program will only work on Linux.
