Django Twitter OAuth认证

Question

我正在尝试在我的Django应用程序中实现通过OAuth进行Twitter认证，但在收到Twitter的回调后遇到了这个错误：

Traceback:

File "/Library/Python/2.6/site-packages/django/core/handlers/base.py" in get_response
  100.                     response = callback(request, *callback_args, **callback_kwargs)
File "/Users/flavioramos/projects/sobo/sobo/../sobo/views.py" in twitter_authenticated
  105.     auth_login(request, user)
File "/Library/Python/2.6/site-packages/django/contrib/auth/__init__.py" in login
  71.     user.save()
File "/Library/Python/2.6/site-packages/django/contrib/auth/models.py" in save
  430.         raise NotImplementedError

Exception Type: NotImplementedError at /login/authenticated
Exception Value: 

我的登录/认证视图如下：

def twitter_authenticated(request):
    token = oauth.Token(request.session['request_token']['oauth_token'],
        request.session['request_token']['oauth_token_secret'])
    client = oauth.Client(consumer, token)

    resp, content = client.request(access_token_url, "GET")
    if resp['status'] != '200':
        print content
        raise Exception("Invalid response from Twitter.")

    access_token = dict(cgi.parse_qsl(content))

    try:
        user = User.objects.get(username=access_token['screen_name'])
    except User.DoesNotExist:
        user = User.objects.create_user(access_token['screen_name'],
            '%s@twitter.com' % access_token['screen_name'],
            access_token['oauth_token_secret'])

        profile = Profile()
        profile.user = user
        profile.oauth_token = access_token['oauth_token']
        profile.oauth_secret = access_token['oauth_token_secret']
        profile.save()


    user = authenticate(username=access_token['screen_name'],password=access_token['oauth_token_secret'])

    auth_login(request, user)

    return HttpResponseRedirect('/')

这段代码来自一个python-oauth2的示例应用。

我需要为此编写自己的认证后端吗？

我对Django还很陌生，任何帮助都将不胜感激。

谢谢，

Answer 1

我不太确定，但我觉得

*auth_login(request, user)*

应该是：login(request, user)

（当然，这个login应该在你的登录/认证视图的顶部从django.contrib.auth导入）

Answer 2

我也遇到过同样的问题。看起来oauthtwitter用到的库发生了变化。要修复你本地的版本，可以按照以下步骤操作：

在：

/usr/local/lib/python2.6/dist-packages/oauth_python_twitter-1.0-py2.6.egg/oauthtwitter.py

找到第37行，把它从：

Api.__init__(self, access_token.key, access_token.secret)

改成：

Api.__init__(self, consumer_key, consumer_secret, access_token.key, access_token.secret)

现在所有需要的变量都能正确传递了。
