Django的Python Social Auth引发Authforbidden异常

作者:互联网

我正在将Django 1.10与python 2.7和social-auth-app-django(1.2.0)一起使用.它是Python Social Auth库的一部分.

我希望仅将登录限制为我公司的域ID,因此我从库中使用了此设置.

SOCIAL_AUTH_GOOGLE_OAUTH2_WHITELISTED_DOMAINS=['mycompany.in']

现在,如果您尝试按预期使用任何其他域登录,则会引发错误.

我的目标是捕获此异常并向用户显示自定义页面.但是对于我的一生,我无法做到.

如果我将Debug设置为False,它将用户重定向到我的

LOGIN_ERROR_URL='/'

页面,但无法将我的自定义消息传递给用户

这是我的setting.py的一部分

调试=假

    MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'social_django.middleware.SocialAuthExceptionMiddleware',
]

#social auth
SOCIAL_AUTH_GOOGLE_OAUTH2_KEY= "9******6.apps.googleusercontent.com"
SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET="W*****x"
SOCIAL_AUTH_GOOGLE_OAUTH2_WHITELISTED_DOMAINS=['mycompany.in']
LOGIN_URL = 'login'
LOGIN_REDIRECT_URL = 'upload_file'
LOGOUT_URL = 'logout'
LOGIN_ERROR_URL='logout

在我看来,我有这段代码可以处理异常

from social_django.middleware import SocialAuthExceptionMiddleware
from social_core.exceptions import AuthForbidden


    class SocialAuthExceptionMiddleware(SocialAuthExceptionMiddleware):
      def process_exception(self, request, exception):
        print "exception occured"
        if hasattr(social_exceptions, 'AuthForbidden'):
          print "hello two"
          return HttpResponse("I'm a exception %s" % exception)
        else:
          print "other exception"
          raise exception

我什至尝试过

def process_template_response(self):
    print "response"'

def get_redirect_uri(request, exception):
    print "URL"

但无济于事.

我关注了这些链接
python-social-auth AuthCanceled exception

http://python-social-auth-docs.readthedocs.io/en/latest/configuration/django.html#exceptions-middleware

这是debug设置为False时的输出:

“AuthForbidden at /app/oauth/complete/google-oauth2/
Your credentials aren’t allowed”

解决方法:

>需要在settings.py中为SOCIAL_AUTH_LOGIN_ERROR_URL设置值
>扩展SocialAuthExceptionMiddleware类&需要覆盖“ get_message”方法
>处理错误URL将消息显示给用户.

例如

中间件

from social_django.middleware import SocialAuthExceptionMiddleware

class CustomSocialAuthExceptionMiddleware(SocialAuthExceptionMiddleware):
    def get_message(self, request, exception):
       default_msg = super(CustomSocialAuthExceptionMiddleware).get_message(request, exception) # in case of display default message
       return "Custom messages text write here."

settings.py

SOCIAL_AUTH_LOGIN_ERROR_URL = '/error_page/'
MIDDLEWARE = [
'...',
'path.to.custom.middleware.CustomSocialAuthExceptionMiddleware',
]

URL.py

from django.conf.urls import url

from views import ErrorPage

urlpatterns = [
    url(r'^error_page/$', ErrorPage.as_view(), name="error-page"),
]

view.py

from django.views.generic.base import TemplateView

class ErrorPage(TemplateView):
    template_name = 'error.html'

error.html(模板)

....
   <body>
     {% if messages %}
        <ul class="messages">
           {% for message in messages %}
               <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }} </li>
        {% endfor %}
        </ul>
    {% endif %}
   </body>
....

如果您正在使用django消息框架.在不使用django消息框架的情况下,中间件将消息添加到GET参数中,该参数可以显示在错误页面上.
