Django-rest-framework { "detail" ： "Authentication credentials were not provided." } using django-re

Question

我看到错误{"detail": "Authentication credentials were not provided." }。

这是我用于登录的代码

我的型号：

class User(AbstractBaseUser):
STUDENT = 'STU'
SCHOOL = 'SCH'
INSTITUTE = 'INST'
TUTOR = 'TUT'
ACCOUNT_TYPE_CHOICES = [
(STUDENT, 'Student'),
(SCHOOL, 'School'),
(INSTITUTE, 'Institute'),
(TUTOR, 'Tutor'),
]
account_type = models.CharField(
max_length=4,
choices=ACCOUNT_TYPE_CHOICES,
default=SCHOOL,
)
name = models.CharField(max_length=255)
email = models.EmailField(unique=True,max_length=255)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
is_admin = models.BooleanField(default=False)
timestamp = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['name','account_type']
objects=UserManager()
def __str__(self):
return self.email
def has_perm(self,perm,obj=None):
return True
def has_module_perms(self,app_label):
return True
@property
def is_staff(self):
return self.is_admin

我的序列化程序：

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

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

# I guess the validate function is not working .
class LoginSerializer(serializers.Serializer):
email = serializers.EmailField()
password = serializers.CharField()
def validate(self, data):
user = authenticate(request=None,**data)
if user and user.is_active:
return user
raise serializers.ValidationError("Incorrect Credentials")

我的看法：

from rest_framework import generics, permissions,authentication
from rest_framework.response import Response
from knox.models import AuthToken
from knox.views import LoginView as KnoxLoginView
from .serializers import UserSerializer, RegisterSerializer, LoginSerializer
from django.contrib.auth import authenticate,login
# Login API

class LoginAPI(generics.GenericAPIView):
serializer_class = LoginSerializer
# authentication_class=[authentication.BasicAuthentication]
def post(self, request, *args, **kwargs):
serializer = LoginSerializer(data=request.data)
serializer.is_valid(raise_exception=True)
user = serializer.validated_data
return Response({
"user": UserSerializer(user, context=self.get_serializer_context()).data,
"token": AuthToken.objects.create(user)[1]
})

我的蛋清：

from django.urls import path, include
from .api import RegisterAPI, LoginAPI
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/logout/', knox_views.LogoutView.as_view(), name='knox_logout')
]

此外，当我提供注册时生成的令牌时，它会显示用户处于非活动状态或已死亡状态。但当我检查我的数据库和令牌到期时间时，它仍然处于活动状态。我尝试过不同的第三方库，比如rest-auth，它也给出了相同的错误。我也检查了许多关于同一主题的其他答案，但应用它们也无济于事。

您应该从REST_FRAMEWORK设置中的settings.py文件中确认，您已将"DEFAULT_PERMISSION_CLASSES"设置为"REST_FRAMEWORK.permissions.AllowAny"。

应该是这样的：

# Rest framework
REST_FRAMEWORK = {
# Use Django's standard `django.contrib.auth` permissions,
# or allow read-only access for unauthenticated users.
'DEFAULT_PERMISSION_CLASSES': [
'rest_framework.permissions.AllowAny',
],
}
