• views.py

  from django.http import HttpResponse
  from django.views import View
  from django.utils.decorators import method_decorator  # 加装饰器用
    
  # 通过method_decorator方法给get、posts加装饰器
  @method_decorator(装饰器函数名,name='dispatch')
  class Login(View):
    	# 通过method_decorator方法给get、post加装饰器
      @method_decorator(装饰器函数名)
  		def dispatch(self, request, *args, **kwargs):
        	# 相当于给get、post加装饰器
          print('get、post请求之前')
          # 分发器，调用get、post
        	super(Login, self).dispatch(self, request, *args, **kwargs)
          # 相当于给get、post加装饰器
          print('get、post请求之后')
      		return HttpResponse('OK')
      # 单一装饰器
      @method_decorator(装饰器函数名)
      def get(self, request, *args, **kwargs):
          return HttpResponse('OK')
