我正在尝试创建一个APIView（www.example.com中的路径'create-room'urls.py），如果会话已经存在，则可以在其中编辑房间模型，如果会话不存在，则可以创建新的房间模型。在APIView中，this is what I am getting.我不知道为什么它说GET /api/create-room，这导致了HTTP 405 Method Not Allowed的错误。如何将请求更改为POST请求，如shown in the tutorial（将GET改为POST /api/create-room
我的代码：

# views.py
from django.shortcuts import render
from rest_framework import generics, status
from .serializers import RoomSerializer, CreateRoomSerializer
from .models import Room
from rest_framework.views import APIView
from rest_framework.response import Response

# Create your views here.

class RoomView(generics.ListAPIView):
    queryset = Room.objects.all()
    serializer_class = RoomSerializer

# The problematic API View
class CreateRoomView(APIView):
    serializer_class = CreateRoomSerializer

    def post(self, request, format=None):
        if not self.request.session.exists(self.request.session.session_key):
            self.request.session.create()

        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            guest_can_pause = serializer.data.get('guest_can_pause')
            votes_to_skip = serializer.data.get('votes_to_skip')
            host = self.request.session.session_key
            # Check if host already has a session
            queryset = Room.objects.filter(host=host)
            if queryset.exists():
                room = queryset[0]
                room.guest_can_pause = guest_can_pause
                room.votes_to_skip = votes_to_skip
                room.save(update_fields=['guest_can_pause', 'votes_to_skip'])
                return Response(RoomSerializer(room).data, status=status.HTTP_200_OK)
            else:
                room = Room(host=host, guest_can_pause=guest_can_pause,
                            votes_to_skip=votes_to_skip)
                room.save()
                return Response(RoomSerializer(room).data, status=status.HTTP_201_CREATED)

        return Response({'Bad Request': 'Invalid data...'}, status=status.HTTP_400_BAD_REQUEST)

# serializers.py
from rest_framework import serializers
from .models import Room

class RoomSerializer(serializers.ModelSerializer):
    class Meta:
        model = Room
        fields = ('id', 'code', 'host', 'guest_can_pause',
                  'votes_to_skip', 'created_at')

class CreateRoomSerializer(serializers.ModelSerializer):
    class Meta:
        model = Room
        fields = ('guest_can_pause', 'votes_to_skip')

# urls.py
from django.urls import path
from . import views

# URLConf
urlpatterns = [
    path('room', views.RoomView.as_view()),
    path('create-room', views.CreateRoomView.as_view())
]

我已经尝试将这段代码添加到视图中

def get(self, request, format=None):
    queryset = Room.objects.all()
    serializer = self.serializer_class()
    return Response(serializer.data)

但是这个请求是一个GET请求，当我尝试在API视图上发出POST请求时，它会永远加载：This is where I try to make a POST request that loads forever的

字符串
建议将APIView统一为一个

# urls.py
from django.urls import path
from . import views

# URLConf
urlpatterns = [
    path('api/rooms/', views.RoomAPIView.as_view()),
]

你可以在链接http：//localhost：8000/api/rooms/GET & POST中看到API文档
