python-social-auth AuthCanceled 異常

Question

我在我的 Django 應用程序中使用 python-social-auth 通過 Facebook 進行身份驗證。 但是當用戶嘗試登錄時，他們已被重定向到 Facebook 應用程序頁面，並且他們單擊“取消”按鈕時，會出現以下異常：

ERROR 2014-01-03 15:32:15,308 base :: Internal Server Error: /complete/facebook/
Traceback (most recent call last):

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

有沒有辦法抓住它 Django？

Answer 1

python-social-auth是django-social-auth的更新派生版本。

AlexYar 的答案可以通過修改settings.py並進行以下更改來稍微修改以與python-social-auth一起使用：

1. 添加一個中間件來處理 SocialAuthException

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

2. 發生異常時重定向到的 URL

    SOCIAL_AUTH_LOGIN_ERROR_URL = '/'

3. 請注意，您還需要設置

   DEBUG = False

這就是全部或閱讀http://python-social-auth.readthedocs.org/en/latest/configuration/django.html#exceptions-middleware

Answer 2

您可以創建一個中間件並捕獲任何異常，異常列表： https : //github.com/omab/python-social-auth/blob/master/social/exceptions.py在這種情況下您的 AuthCanceled 異常。

中間件.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

設置.py

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

Answer 3

這是@Nicolas 答案的輕微修改，這對我有用。

中間件.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

設置.py

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

Answer 4

只需添加

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

和類似的東西

LOGIN_ERROR_URL = '/'

這就是全部或閱讀http://django-social-auth.readthedocs.org/en/latest/configuration.html#exceptions-middleware

Answer 5

2018年的答案：

1. 將SocialAuthExceptionMiddleware中間件添加到您的配置中：

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

2. 在您的配置中設置SOCIAL_AUTH_LOGIN_ERROR_URL ：

    SOCIAL_AUTH_LOGIN_ERROR_URL = '/login'

現在，當您有DEBUG = False ，當您的用戶在社交身份驗證提供程序的頁面中單擊取消時，他們將被重定向到您的登錄頁面。

當DEBUG = True您仍會在開發過程中在瀏覽器中看到錯誤頁面。

Answer 6

如果您不關心處理異常，請在settings.py執行以下操作

SOCIAL_AUTH_RAISE_EXCEPTIONS = False

Answer 7

這是使用 social_django 更新的導入中間件

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
