python - 无法使用 Django 身份验证

Question

我收到此错误:

TypeError at /auth/
authenticate() missing 1 required positional argument: 'request'

我正在使用 Django 以及 Django Rest Framework。

HTTP POST 如下所示:

{
    "username": "HelloUser",
    "password": "Hello123"
}

查看

@csrf_exempt
@api_view(['POST'])
def authenticate(self, request):
    print(request.data)
    user = authenticate(username=request.data['username'], password=request.data['password'])
    if user is not None:
        return Response({'Status': 'Authenticated'})
    else:
        return Response({'Status': 'Unauthenticated'})

网址

urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'create/', views.create),
    url(r'retrieve/', views.retrieve),
    url(r'auth/', views.authenticate),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

首先，您不应该将 View 名称用作authenticate，因为它会与 Django auth 的authenticate 混合在一起 其次，您不需要在身份验证 View 中使用 self 参数，即 defauthenticate_user(request) 像这样更新您的代码:

查看

from django.contrib.auth import authenticate

@csrf_exempt
@api_view(['POST'])
def authenticate_user(request):
    print(request.data)
    user = authenticate(username=request.data['username'], password=request.data['password'])
    if user is not None:
        return Response({'Status': 'Authenticated'})
    else:
        return Response({'Status': 'Unauthenticated'})

您的 urls.py 将根据 View 名称进行更新:

网址

urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'create/', views.create),
    url(r'retrieve/', views.retrieve),
    url(r'auth/', views.authenticate_user),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
