requests-crtauth

A plugin to support crtauth authentication in Python Requests.

Usage

requests-crtauth works as an authentication plugin for Python Requests. See the authentication documentation for more details. The following arguments may be provided to a new instance of HttpCrtAuth:

username: User to authenticate as. Defaults to $USER.
private_key: A PEM encoded private key string. Overrides signer.
signer: A crtauth SigningPlug instance. Defaults to using the SSH agent (AgentSigner).
version: Integer version of the crtauth protocol. Defaults to version 1.

Here's an example.

In [1]: import requests, requests_crtauth, json, logging
In [2]: logging.basicConfig(level=logging.DEBUG)
In [3]: session = requests.Session()
# HttpCrtAuth() will default to authenticating with your $USER env variable and a key from your SSH agent.
# To specify an explicit key: requests_crtauth.HttpCrtAuth(username='negz', private_key='key data as a string')
In [4]: session.auth = requests_crtauth.HttpCrtAuth()
In [5]: data = json.dumps({'comment': 'I\'m a comment!'})
In [6]: headers = {'content-type': 'application/json; charset=utf-8'}
In [7]: response = session.put('https://db.spotify.net/v1/things/yomaris', data=data, headers=headers)
