csrf cookie 未设置 django rest

Question

在使用 REST 可浏览 API 时，响应工作正常，但当我开始使用邮递员与另一端的前端集成时，响应变为：

 {
  "detail": "CSRF Failed: CSRF cookie not set."
}

我尝试了一切来解决这个错误，但没有任何改变，并检查了这里关于 CSRF 令牌的每个问题，但仍然没有工作

这些是我的代码： 视图.py：

from django.shortcuts import render

from django.http import JsonResponse
from rest_framework.response import Response
from rest_framework import status
from User.serializers import UserDataSerializer, ImageSerializer
from rest_framework.views import APIView
from rest_framework import generics
from User.models import UserData,Image
from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login, logout
from rest_framework.renderers import TemplateHTMLRenderer
from django.views.decorators.csrf import csrf_exempt

@csrf_exempt 
class Signup(APIView):
    def post(self, request, format = None):
       serializer = UserDataSerializer(data = request.data)
       if(serializer.is_valid()):
           user = User.objects.create_user(
               username = serializer.data['username'],
               first_name = serializer.data['first_name'],
               last_name = serializer.data['last_name'],
               email = serializer.data['email'],
               password = serializer.data['password'],
               )
        #add the name because it is not with create_user method
        # user.name = serializer.data['name']
        # user.save()
        login(request, user)
        print ("logged")
        text = {'valid' : True , 'errors' :"ur password"+serializer.data['password']}
        return JsonResponse(serializer.data)
    else:
        return JsonResponse(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

class Login(APIView):
   def post(self, request):
       username = request.data.get('username')
       password = request.data.get('password')
       user = authenticate(username=username, password=password)

       if user is not None:
           login(request, user)
           serializer = UserDataSerializer(user)
           return JsonResponse(serializer.data, status=status.HTTP_302_FOUND)
       else:
           text = {'valid' : False , 'errors' : "Invalid Username or Password"}
           return Response(text, status=status.HTTP_401_UNAUTHORIZED)

class Logout(APIView):
    def get(self, request):
        logout(request)
        return Response({"valid": True}, status=status.HTTP_200_OK)

class ImageUpload(generics.CreateAPIView):

    queryset = Image.objects.all()
    serializer_class = ImageSerializer

Answer 1

你必须像这样在 url 中使用 ensure_csrf_cookie 装饰器

from django.views.decorators.csrf import ensure_csrf_cookie
urlpatterns = [
    url(r'^login/?$', ensure_csrf_cookie(views.Login().as_view())),
]

您还需要添加所有 CORS 设置
