python-social-auth AuthCanceled 异常

Question

我在我的 Django 应用程序中使用 python-social-auth 通过 Facebook 进行身份验证。但是当用户尝试登录时，他们已经被重定向到 Facebook 应用页面，点击“取消”按钮，出现以下异常:

ERROR 2014-01-03 15:32:15,308 base :: Internal Server Error: /complete/facebook/

    raise AuthCanceled(self, data.get('error_description', ''))
AuthCanceled: Authentication process canceled

有什么方法可以捕获它 Django 吗？

Answer 1

python-social-auth 是 django-social-auth 的更新的衍生版本。

AlexYar 的 answer可以通过修改 settings.py 进行轻微修改以使用 python-social-auth 并进行以下更改:

1. 添加一个中间件来处理 SocialAuthException

   MIDDLEWARE_CLASSES += (
       'social.apps.django_app.middleware.SocialAuthExceptionMiddleware',
   )
   

2. 发生异常时重定向到的 URL

   SOCIAL_AUTH_LOGIN_ERROR_URL = '/'
   

3. 注意，你还需要设置

   DEBUG = False
   

这就是全部或阅读http://python-social-auth.readthedocs.org/en/latest/configuration/django.html#exceptions-middleware
