01 前后端分离介绍

• FBV，function base views，其实就是编写函数来处理业务请求。

  from django.contrib import admin
  from django.urls import path
  from app01 import views
  urlpatterns = [
      path('users/', views.users),
  ]
  

  from django.http import JsonResponse
  
  def users(request,*args, **kwargs):
      if request.method == "GET":
          return JsonResponse({"code":1000,"data":"xxx"})
      elif request.method == 'POST':
          return JsonResponse({"code":1000,"data":"xxx"})
      ...
  

• CBV，class base views，其实就是编写类来处理业务请求。

  from django.contrib import admin
  from django.urls import path
  from app01 import views
  urlpatterns = [
      path('users/', views.UserView.as_view()),
  ]
  

  from django.views import View
  
  class UserView(View):
      def get(self, request, *args, **kwargs):
          return JsonResponse({"code": 1000, "data": "xxx"})
  
      def post(self, request, *args, **kwargs):
          return JsonResponse({"code": 1000, "data": "xxx"})
  

其实，CBV和FBV的底层实现本质上相同的。
