Question

I just updated to Twython 2.3.4, but now my Twitter auth stops working. It fails on the ‘ auth_props = twitter.get_authentication_tokens()’ line. Any idea what went wrong? Thanks in advance!

The python code to do Twitter auth using Twython is below:

def begin_auth(request):
    twitter = Twython(
        twitter_token = TWITTER_KEY,
        twitter_secret = TWITTER_SECRET,
        callback_url = request.build_absolute_uri(reverse('portnoy.views.thanks'))
    )
    # Request an authorization url to send the user to...
    auth_props = twitter.get_authentication_tokens()

I have the following error on the line above: TwythonAuthError: “Seems something couldn’t be verified with your OAuth junk. Error: 401, Message: Failed to validate oauth signature and token”

    # Then send them over there, durh.
    request.session['request_token'] = auth_props
    return HttpResponseRedirect(auth_props['auth_url'])

def thanks(request, redirect_url='/'):
    c = RequestContext(request)
    # for permanent ones and store them...
    twitter = Twython(
        twitter_token = TWITTER_KEY,
        twitter_secret = TWITTER_SECRET,
        oauth_token = request.session['request_token']['oauth_token'],
        oauth_token_secret = request.session['request_token']['oauth_token_secret']
     )

    # Retrieve the tokens we want...
    authorized_tokens = twitter.get_authorized_tokens()
    request.session['request_tokens'] = authorized_tokens
    debug('thanks', request.session['request_tokens'])

    user = User.objects.filter(username=authorized_tokens['screen_name'])
    if user.exists():
        user = user[0]
        user.backend='django.contrib.auth.backends.ModelBackend'     
        auth.login(request,user)
    else:
        return render_to_response('twitter_register.html', c)   
    return HttpResponseRedirect(redirect_url)

I’m the author of Twython.

What version of Requests are you running under the hood? There was recently an issue where people kept running into various OAuth-related errors due to an upstream bug. Curious if it’s related to that…
