【问题标题】:django rest framework TokenAuthentication not workingdjango rest框架TokenAuthentication不起作用
【发布时间】:2015-03-30 08:07:50
【问题描述】:

想要使用基于令牌的身份验证系统,所以 api 调用使用 DRF 获取列表,它总是抛出错误,我在本地系统中测试了这个 api。

"detail":"未提供身份验证凭据。"

设置.py

REST_FRAMEWORK = {

    'DEFAULT_AUTHENTICATION_CLASSES': (
        #'rest_framework.permissions.IsAuthenticated',

        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'oauth2_provider.ext.rest_framework.OAuth2Authentication',        
        'rest_framework.authentication.TokenAuthentication',        
    ),

    'DEFAULT_RENDERER_CLASSES': (
        'rest_framework.renderers.JSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
    ),

    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
        'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly',

    ),       
}

序列化器.py

class MyListSerializer(SignUpSerializer):

    class Meta:
        model = MyMod
        fields = ('no', 'yes')       

view.py

class MyList(generics.ListCreateAPIView):

    queryset = MyMod.objects.all()
    serializer_class = MyListSerializer
    authentication_classes = (TokenAuthentication,)

网址:

curl -H "Authorization: Bearer MDgYnKeoRsp0O4Hfgr9ka5tdfkKs6Y" http://127.0.0.1:8000/my/

错误:

{"detail":"Authentication credentials were not provided."}

【问题讨论】:

  • 你不是在混合 OAuth2Authentication 和 TokenAuthentication 吗?对于 TokenAuthentication,您应该使用此标头: Authorization: Token MDgYnKeoRsp0O4Hfgr9ka5tdfkKs6Y ("Token", not "Bearer")
  • 感谢您的回复: curl -i -H "Authorization: Token MDgYnKeoRsp0O4Hfgr9ka5tdfkKs6Y" 127.0.0.1:8000/my 同样的错误 {"detail":"Authentication credentials were not provided."}
  • @RaphaëlBraud 是在类视图中使用 TokenAuthentication 的正确方法。
  • 使用 'Token' 前缀 Authorization 标头值是正确的方法,但你是如何得到 "MDgYnKeoRsp0O4Hfgr9ka5tdfkKs6Y" 的?你应该使用类似的东西: Token.objects.get_or_create(user=user).key 。是这样吗?
  • 权限的主要问题 permission_classes = [TokenHasReadWriteScope] 而不是 authentication_classes = (TokenAuthentication,)

【解决方案1】:

问题:

class MyList(generics.ListCreateAPIView):

    queryset = MyMod.objects.all()
    serializer_class = MyListSerializer
    authentication_classes = (TokenAuthentication,)

解决方案:

class MyList(generics.ListCreateAPIView):

    queryset = MyMod.objects.all()
    serializer_class = MyListSerializer
    permission_classes = [TokenHasReadWriteScope]

curl -H "授权:承载 MDgYnKeoRsp0O4Hfgr9ka5tdfkKs6Y" http://127.0.0.1:8000
