self.context['request '].user always returns AnonymousUser

Question

我正在尝试在模型序列化程序中获取当前用户

self.context['request'].user

但它总是 returns AnonymousUser。这是序列化程序代码片段

class QuestionBlockDetailSerializer(serializers.ModelSerializer):
    isvoted = serializers.SerializerMethodField(read_only=True)

    def get_isvoted(self,obj):
        user = self.context['request'].user
        print self.context['request'].user
        ...

下面是权限和AuthBackends的设置

AUTHENTICATION_BACKENDS = (
'django.contrib.auth.backends.ModelBackend',
'social.backends.google.GoogleOAuth2',
'social.backends.facebook.FacebookOAuth2',)

 'DEFAULT_AUTHENTICATION_CLASSES': (
    'oauth2_provider.ext.rest_framework.OAuth2Authentication',
    'rest_framework_social_oauth2.authentication.SocialAuthentication',
    'rest_framework.authentication.TokenAuthentication',

),

查看：

class QuestionBlockDetailAPI(generics.RetrieveAPIView, mixins.UpdateModelMixin, mixins.DestroyModelMixin):
   permission_classes =[IsAuthenticatedOrReadOnly]
   serializer_class = QuestionBlockDetailSerializer
   queryset= Question_Block.objects.all()
   lookup_field = 'q_slug'

   def delete(self, request, *args, **kwargs):
    return self.destroy(request,*args, **kwargs)

   def put(self, request, *args, **kwargs):
    return self.update(request,*args,**kwargs)

我尝试添加 Session 和 BasicAuthentication，但它总是返回 AnonymousUser。请帮我解决这个问题。

Answer 1

您正在 QuestionBlockDetailAPI 视图中使用 IsAuthenticatedOrReadOnly 权限 class。因此，未经身份验证的用户可以读取您的 api。因此，当未经身份验证的用户访问您时，self.context['request'].user 是 AnonymousUser api。

你可以通过改变你的def get_isvoted(self,obj):方法来解决这个问题，比如：

def get_isvoted(self,obj):
    if self.context['request'].user.is_authenticated():
        return self.context['request'].user.isvoted
    else:
        return False

Answer 2

只需在条件

中使用user.is_authenticated

if self.context['request'].user.is_authenticated:
    return true

self.context['request '].user always returns AnonymousUser

self.context['request '].user always returns AnonymousUser
