有没有办法捕捉到Django？

解决方案

您可以创建一个中间件并捕获任何异常，
例外列表： https://github.com/omab/python-social-auth/blob/master/social/exceptions.py
在这种情况下你的AuthCanceled异常。

middleware.py

 $ code 
 
 from social.apps.django_app.middleware import SocialAuthExceptionMiddleware 
 from django.shortcuts import HttpResponse 
 from social import exceptions as social_exceptions 
 
 class SocialAuthExceptionMiddleware（SocialAuthExceptionMiddleware）：
 def process_exception（self，request，exception）：
 if hasattr（social_exceptions，'AuthCanceled'）：
 return HttpResponse 小马％s％excep 
 else：
 raise exception 
 
  
 

settings.py

 
  
 
 MIDDLEWARE_CLASSES = 
 ..... 
'pat_to_middleware.SocialAuthExceptionMiddleware'，
）
 
  
 

I'm using python-social-auth in my Django application for authentication via Facebook. But when a user tries to login and when it's been refirected to Facebook app page clicks on "Cancel" button, appears the following exception:

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

Is the any way to catch it Django?

解决方案

you can create a middleware and catch any exceptions, exception list: https://github.com/omab/python-social-auth/blob/master/social/exceptions.py in this case your AuthCanceled Exception.

middleware.py

    from social.apps.django_app.middleware import SocialAuthExceptionMiddleware
    from django.shortcuts import HttpResponse
    from social import exceptions as social_exceptions

    class SocialAuthExceptionMiddleware(SocialAuthExceptionMiddleware):
        def process_exception(self, request, exception):
            if hasattr(social_exceptions, 'AuthCanceled'):
                return HttpResponse("I'm the Pony %s" % exception)
            else:
                raise exception

settings.py

    MIDDLEWARE_CLASSES = (
             .....
            'pat_to_middleware.SocialAuthExceptionMiddleware',
    )
