为什么我的电话号码和密码都是空的？

Question

我正在为我的登录视图使用 django restframework。虽然我通过 POSTMAN 传递 json，但我得到的是空的电话和密码。

class LoginView(APIView):
    
    permission_classes = (permissions.AllowAny,)

    def post(self,request):
        phone = request.POST.get('phone')
        password = request.POST.get('password')
        
        if phone and password:
            get_user= CustomUser.objects.filter(phone=phone).first()
            username = get_user.username
            user = authenticate(request, username=username, password=password)
            if user is not None:
                login(request, user)
                return Response({"message": "Your are logged In!"}, status=status.HTTP_200_OK)
            else:
                return Response({"message": "Either phone number or password is wrong!"}, status=status.HTTP_400_BAD_REQUEST)
        else:
            return Response({"message": "Please type again!"}, status=status.HTTP_400_BAD_REQUEST)  

我使用 POSTMAN 传递的 json

{
    "phone": "923337195234",
    "password": "123456789"
}

这是结果

{
    "message": "Please type again!"
}

如果我注释掉第一个 if-else 语句

class LoginView(APIView):
    
    permission_classes = (permissions.AllowAny,)

    def post(self,request):
        phone = request.POST.get('phone')
        password = request.POST.get('password')
        
        # if phone and password:
        get_user= CustomUser.objects.filter(phone=phone).first()
        username = get_user.username
        user = authenticate(request, username=username, password=password)
        if user is not None:
            login(request, user)
            return Response({"message": "Your are logged In!"}, status=status.HTTP_200_OK)
        else:
            return Response({"message": "Either phone number or password is wrong!"}, status=status.HTTP_400_BAD_REQUEST)
        # else:
        #     return Response({"message": "Please type again!"}, status=status.HTTP_400_BAD_REQUEST)

我得到了这个结果。为什么手机和密码都是空的？

AttributeError: 'NoneType' object has no attribute 'username'

这是我的 urls.py

 path('login/', LoginView.as_view(), name="user_login")

您前端的json payload 应该以request.data 结尾。你应该尝试的是：

phone = request.data.get('phone')
password = request.data.get('password')
