requests-oauth

This plugins adds OAuth v1.0 support to @kennethreitz well-known requests library providing both header and url-encoded authentication.

requests-oauth wants to provide the simplest and easiest way to do OAuth in Python. It was initially based on python-oauth2 (which looks unmaintained), kudos to the authors and contributors for doing a huge effort in providing OAuth to python httplib2. From that point on, the code base has been cleaned, fixing several bugs and heavily refactoring it to eliminate dependencies with python-oauth2, being now a stand-alone plugin.

Installation

You can install requests-oauth by simply doing:

pip install requests-oauth

Usage

Import the hook doing:

from oauth_hook import OAuthHook

You can initialize the hook passing it 5 parameters: access_token, access_token_secret, consumer_key, consumer_secret and header_auth. First two access_token and access_token_secret are optional, in case you want to retrieve those from the API service (see later for an example). There are two ways to do initialize the hook. First one:

oauth_hook = OAuthHook(access_token, access_token_secret, consumer_key, consumer_secret, header_auth)

The header_auth parameter lets you chose the authentication method used. It's a boolean, if you set it to True you will be using an Authorization header. If your API supports this authentication method, it's the one you should be using and the prefered method by the OAuth spec (RFC 5849), an example would be Twitter's API. By default header_auth is set to False, which means url encoded authentication will be used. This is because this the most widely supported authentication system.

If you are using the same consumer_key and consumer_secret all the time, you probably want to setup those fixed, so that you only have to pass the token parameters for setting the hook:

OAuthHook.consumer_key = consumer_key
OAuthHook.consumer_secret = consumer_secret
oauth_hook = OAuthHook(access_token, access_token_secret, header_auth=True)

Now you need to pass the hook to python-requests, you probably want to do it as a session, so you don't have to do this every time:

client = requests.session(hooks={'pre_request': oauth_hook})

What you get is python-requests client which you can use the same way as you use requests API. Let's see a GET example:

response = client.get('http://api.twitter.com/1/account/rate_limit_status.json')
results = json.loads(response.content)

And a POST example:

response = client.post('http://api.twitter.com/1/statuses/update.json', {'status': "Yay! It works!", 'wrap_links': True})

Beware that you are not forced to pass the token information to the hook. That way you can retrieve it from the API. Let's see a Twitter example:

client = requests.session(hooks={'pre_request': OAuthHook(consumer_key=consumer_key, consumer_secret=consumer_secret)})
response = client.get('https://api.twitter.com/oauth/request_token')
response = parse_qs(response.content)
print "Token: %s  Secret: %s" % (response['oauth_token'], response['oauth_token_secret'])

Testing

If you want to run the tests, you will need to copy test_settings.py.template into test_settings.py. This file is in the .gitignore index, so it won't be committed:

cp test_settings.py.template test_settings.py

Then fill in the information there. At the moment, the testing of the library is done in a functional way, doing a GET and a POST request against OAuth API services, so use a test account and not your personal account:

./tests.py
