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，当他们点击“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/

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

有什么方法可以抓住它 Django 吗？

python-social-auth是django-social-auth.

AlexYar 的答案可以python-social-auth通过settings.py以下更改进行稍微修改以使用：

  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. 请注意，您还需要设置

    DEBUG = False

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

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

中间件.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

设置.py



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

这是对@Nicolas 答案的轻微修改，这对我有用。

中间件.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

设置.py

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

2018年的答案：

  1. 将SocialAuthExceptionMiddleware中间件添加到您的配置中：

    MIDDLEWARE_CLASSES = [
    ...
    'social_django.middleware.SocialAuthExceptionMiddleware',
]

  2. 在您的配置中设置SOCIAL_AUTH_LOGIN_ERROR_URL：

    SOCIAL_AUTH_LOGIN_ERROR_URL = '/login'

现在，当您拥有 时DEBUG = False，当您的用户在社交身份验证提供商页面中单击取消时，他们将被重定向到您的登录页面。

当DEBUG = True您在开发过程中仍会在浏览器中看到错误页面时。

只需添加

MIDDLEWARE_CLASSES = ('social_auth.middleware.SocialAuthExceptionMiddleware', )

和类似的东西

LOGIN_ERROR_URL = '/'

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

如果您不关心处理异常，请在您的settings.py

SOCIAL_AUTH_RAISE_EXCEPTIONS = False

看到这个答案：如何解决身份验证过程取消错误？

这是使用 social_django 更新的导入中间件

from social_django.middleware import SocialAuthExceptionMiddleware
from social_core import exceptions as social_exceptions
from django.shortcuts import HttpResponse
from django.shortcuts import render, redirect

class FacebookAuthCanceledExceptionMiddleware(SocialAuthExceptionMiddleware):

    def process_exception(self, request, exception):
        if hasattr(social_exceptions, 'AuthCanceled'):
            return redirect('auth_login')
        else:
            raise exception
