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并且当它被重定向到Facebook应用页面点击"取消"按钮时,会出现以下异常:

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

AuthCanceled: Authentication process canceled

有没有办法抓住它Django？

python-social-auth是一个较新的派生版本django-social-auth.

可以稍微修改AlexYar的答案,python-social-auth通过settings.py以下更改进行修改:
这是全部或阅读http://python-social-auth.readthedocs.org/en/latest/configuration/django.html#exceptions-middleware

这是@Nicolas答案的略微修改,这对我有用.

middleware.py

from social.apps.django_app.middleware import SocialAuthExceptionMiddleware
from django.shortcuts import render
from social.exceptions import AuthCanceled

class SocialAuthExceptionMiddleware(SocialAuthExceptionMiddleware):
    def process_exception(self, request, exception):
        if type(exception) == AuthCanceled:
            return render(request, "pysocial/authcancelled.html", {})
        else:
            pass

settings.py

MIDDLEWARE_CLASSES += (
'myapp.middleware.SocialAuthExceptionMiddleware',
)

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 在这种情况下您的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',
    )
