Overview

This code was originally forked from Leah Culver and Andy Smith's oauth.py code. Some of the tests come from a fork by Vic Fryzel, while a revamped Request class and more tests were merged in from Mark Paschal's fork. A number of notable differences exist between this code and its forefathers:

• 100% unit test coverage.
• The DataStore object has been completely ripped out. While creating unit tests for the library I found several substantial bugs with the implementation and confirmed with Andy Smith that it was never fully baked.
• Classes are no longer prefixed with OAuth.
• The Request class now extends from dict.
• The library is likely no longer compatible with Python 2.3.
• The Client class works and extends from httplib2. It's a thin wrapper that handles automatically signing any normal HTTP request you might wish to make.

Signing a Request

import oauth2 as oauth
import time

# Set the API endpoint 
url = "http://example.com/photos"

# Set the base oauth_* parameters along with any other parameters required
# for the API call.
params = {
    'oauth_version': "1.0",
    'oauth_nonce': oauth.generate_nonce(),
    'oauth_timestamp': int(time.time())
    'user': 'joestump',
    'photoid': 555555555555
}

# Set up instances of our Token and Consumer. The Consumer.key and 
# Consumer.secret are given to you by the API provider. The Token.key and
# Token.secret is given to you after a three-legged authentication.
token = oauth.Token(key="tok-test-key", secret="tok-test-secret")
consumer = oauth.Consumer(key="con-test-key", secret="con-test-secret")

# Set our token/key parameters
params['oauth_token'] = tok.key
params['oauth_consumer_key'] = con.key

# Create our request. Change method, etc. accordingly.
req = oauth.Request(method="GET", url=url, parameters=params)

# Sign the request.
signature_method = oauth.SignatureMethod_HMAC_SHA1()
req.sign_request(signature_method, consumer, token)

Using the Client

The oauth2.Client is based on httplib2 and works just as you'd expect it to. The only difference is the first two arguments to the constructor are an instance of oauth2.Consumer and oauth2.Token (oauth2.Token is only needed for three-legged requests).

import oauth2 as oauth

# Create your consumer with the proper key/secret.
consumer = oauth.Consumer(key="your-twitter-consumer-key", 
    secret="your-twitter-consumer-secret")

# Request token URL for Twitter.
request_token_url = "http://twitter.com/oauth/request_token"

# Create our client.
client = oauth.Client(consumer)

# The OAuth Client request works just like httplib2 for the most part.
resp, content = client.request(request_token_url, "GET")
print resp
print content
