Twitter API, OAuth and decorators

In my current project I had a task to use twitter API. Twitter uses OAuth for authentication, which is pretty dreary. To avoid fiddling with it all the time, I've moved authentication to decorator, now it looks like this:

@twitter_api
def tweet_hello(request, api):
    api.update_status('hello')
# ...

Decorator checks if key is available, and, if needed - initiates authentication. User is redirected to twitter, grants permission and is redirected back to site, to the same place where he left off. If key is available - nothing happens, just view is launched as usual.

It's convenient that there's no need for additional twitter settings in user profile.

tweepy is used as an API wrapper.

def twitter_api(view):
    def wrapped(request, args, *kwargs):
        callback_url = absolute_url(oauth_endpoint)
        auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET, callback_url)

        if 'twitter_access_token' in request.session:
            key, secret =     request.session['twitter_access_token']
            auth.set_access_token(key, secret)
            return view(request, api=tweepy.API(auth), *args, **kwargs)

        request.session['twitter_action'] = request.path
        redirect_url = auth.get_authorization_url()
        request.session['twitter_request_token'] = (auth.request_token.key, auth.request_token.secret)
        return redirect(redirect_url)

    return wrapped


def oauth_endpoint(request):
    callback_url = absolute_url(oauth_endpoint)
    auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET, callback_url)
    key, secret = request.session.pop('twitter_request_token')
    auth.set_request_token(key, secret)
    verifier = request.REQUEST.get('oauth_verifier')
    auth.get_access_token(verifier)
    request.session['twitter_access_token'] = (auth.access_token.key, auth.access_token.secret)
    return redirect(request.session.pop('twitter_action'))
  • of course, you need to wrap everything in try..except blocks and process errors accordingly
  • absolute_url should return full url, with http://
  • apart from request.path you can also store POST and GET.
  • path can be passed as an argument to callback_url
