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

我已经尝试了所有可用的互联网解决方案，添加了

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES':(
        'knox.auth.TokenAuthentication',
        'rest_framework.authentication.TokenAuthentication',
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    ),
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAdminUser',
        'rest_framework.permissions.IsAuthenticated',
    ]
}

但没有什么对我有利。我在下面添加了 serilizers.py 和 api.py 文件。请查看它们并告诉我是否有其他方法可以解决此问题。以下是 serializers.py 文件代码

from rest_framework import serializers
from django.contrib.auth.models import User
from django.contrib.auth import authenticate

# User Serializer
class UserSerializer(serializers.ModelSerializer):
  class Meta: 
    model = User
    fields = ('id', 'username', 'email')

# Register Serializer
class RegisterSerializer(serializers.ModelSerializer):
  class Meta:
    model = User
    fields = ('id', 'username', 'email', 'password')
    extra_kwargs = {'password': {'write_only': True}}

  def create(self, validated_data):
    user = User.objects.create_user(validated_data['username'], validated_data['email'], validated_data['password'])

    return user

# Login Serializer
class LoginSerializer(serializers.Serializer):
  username = serializers.CharField()
  password = serializers.CharField()

  def validate(self, data):
    user = authenticate(**data)
    if user and user.is_active:
      return user
    raise serializers.ValidationError("Incorrect Credentials")

api.py 给出为：

from rest_framework import generics, permissions
from rest_framework.response import Response
from knox.models import AuthToken
from .serializers import UserSerializer, RegisterSerializer, LoginSerializer

# Register API
class RegisterAPI(generics.GenericAPIView):
    serializer_class = RegisterSerializer
  
    def post(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.save()
        _, token = AuthToken.objects.create(user)[1]
        return Response({
        "user": UserSerializer(user, context=self.get_serializer_context()).data,
        "token": token
    })

# Login API
class LoginAPI(generics.GenericAPIView):
  serializer_class = LoginSerializer

  def post(self, request, *args, **kwargs):
    serializer = self.get_serializer(data=request.data)
    serializer.is_valid(raise_exception=True)
    user = serializer.validated_data
    _, token = AuthToken.objects.create(user)
    return Response({
      "user": UserSerializer(user, context=self.get_serializer_context()).data,
      "token": token
    })

# Get User API
class UserAPI(generics.RetrieveAPIView):
  permission_classes = [
    permissions.IsAuthenticated,
  ]
  serializer_class = UserSerializer

  def get_object(self):
    return self.request.user

网址.py

from django.urls import path, include
from .api import RegisterAPI, LoginAPI, UserAPI
from knox import views as knox_views

urlpatterns = [
  path('api/auth/', include('knox.urls')),
  path('api/auth/register', RegisterAPI.as_view()),
  path('api/auth/login', LoginAPI.as_view()),
  path('api/auth/user', UserAPI.as_view()),
  path('api/auth/logout', knox_views.LogoutView.as_view(), name='knox_logout')
]

请帮我解决问题。如果没有注册，我无法在 Postman 上发出任何发布请求，登录 API 也将无法工作。

更新您的注册视图以允许未登录，因为您拥有'rest_framework.permissions.IsAuthenticated'默认权限


from rest_framework.permissions import AllowAny

# Register API
class RegisterAPI(generics.GenericAPIView):
    serializer_class = RegisterSerializer
    permission_classes = [AllowAny]
  
    def post(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.save()
        _, token = AuthToken.objects.create(user)[1]
        return Response({
        "user": UserSerializer(user, context=self.get_serializer_context()).data,
        "token": token
    })

要公开 API，您需要在设置中覆盖您的权限。您应该更新您的视图。

from rest_framework.permissions import AllowAny

# Register API
class RegisterAPI(generics.GenericAPIView):
    serializer_class = RegisterSerializer
    permission_classes = [AllowAny]
    authentication_classes=() # To make sure no check if you send Authorization header to server
    ...

也申请您的登录视图。
