DJANGO REST - 基于类的视图 - POST、GET 请求不按定义工作

Question

我已经设置了一个基于类的视图来处理所有请求

• views.py

#Imports

from django.shortcuts import render
from .serializers import UserSerializer
from rest_framework import viewsets
from django.contrib.auth.models import User
from rest_framework.decorators import api_view
from  django.http import HttpResponseForbidden
from rest_framework.response import Response
from rest_framework import status

#Imports End

class UserApiView(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

    def get(self, request, format=None):
        raise HttpResponseForbidden("Get Requests are not allowed here")

    def post(self, request, format=None):
        if request.is_ajax():
            serializer = UserSerializer(data=request.data)
            if serializer.is_valid():
                serializer.save()
                return Response(serializer.data, status=status.HTTP_201_CREATED)

        else:
            raise HttpResponseForbidden("You are not allowed to acess this page")

• 这是序列化程序类（ serializers.py ）

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

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['username','email','password']
        

• urls.py 正在被 DefaultRouter() 处理

from django.urls import include, path
from rest_framework import routers
from .views import UserApiView

router = routers.DefaultRouter()
router.register(r'user',UserApiView,basename="takis")


urlpatterns = [
    path('', include(router.urls)),
]

我希望后端像帖子中所说的那样处理视图并获取请求方法，但它们似乎没有被执行。

我可以正常访问 url ，没有被禁止的错误，它接受请求，即使它们不是 ajax。

Answer 1

我不太清楚你想做什么，我知道你想接受post请求并拒绝get。你可以扩展APIView 而不是ModelViewSet

from rest_framework.views import APIView

class UserApiView(APIView):
  
    def get(self, request, format=None):
        # handle get

    def post(self, request, format=None):
        # handle post

Answer 2

仅当您覆盖其中一种方法时，视图集才有用。

• create()
• retrieve()
• update()
• partial_update()
• destroy()
• list()

如果您需要覆盖get 和post 方法，最好使用APIView 或GenericAPIView。
