1. FBV 정리 및 예시

# urls.py
    
from django.urls import path, include
from . import views
    
urlpatterns = [
	# FBV
	path('cbv/post/', views.post_list),
	path('cbv/post/<int:pk>/',views.post_detail),
]

# views.py

from rest_framework.response import Response

2. APIView 정리 및 예시

   1) APIView

from django.urls import path, include
from . import views

urlpatterns = [
    # FBV
    path('post/', views.PostListAPIView.as_view()),
    path('post/<int:pk>/',views.PostDetailAPIView.as_view()),
]

# views.py

from rest_framework.response import Response
from rest_framework.views import APIView
from .models import Post
from .serializers import PostSerializer

# 포스팅 목록 및 새 포스팅 작성
class PostListAPIView(APIView):
    def get(self, request):
        serializer = PostSerializer(Post.objects.all(), many=True)
    def post(self, request):
        serializer = PostSerializer(data=request.data)
        if serializer.is_valid():
          	serializer.save()
            return Response(serializer.data, status=201)
        return Response(serializer.errors, status=400)  
      
from django.shortcuts import get_object_or_404

# 포스팅 내용, 수정, 삭제
class PostDetailAPIView(APIView):
    def get_object(self, pk):
        return get_object_or_404(Post, pk=pk)
      
    def get(self, request, pk, format=None):
        post = self.get_object(pk)
        serializer = PostSerializer(post)
        return Response(serializer.data)
    
    def put(self, request, pk):
      	post = self.get_object(pk)
        serializer = PostSerializer(post, data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
      
    def delete(self, request, pk):
        post = self.get_object(pk)
        post.delete()
        return Response(status=status.HTTP_204_NO_CONTENT)
