django如何通过类视图使用装饰器

from functools import wraps


def ban_ip(func):
 @wraps(func)
 def wrapper(request,*args,**kwargs):
 IP = request.META.get("REMOTE_ADDR")
 if IP in ["127.0.0.1"]: # 可以添加ip黑名单到列表里
  return HttpResponse("禁止访问")
 return func
 return wrapper

@ban_ip
def get_register(request):
 return render(request,"注册页面.html")


def post_resiger(request):
 name = request.POST.get("name")
 password = request.POST.get("password")
 print(name)
 print(password)
 return HttpResponse("注册成功")

class register(View):
 @method_decorator(ban_ip)
 def get(self,request):
 return render(request,"注册页面.html")

 def post(self,request):
 name = request.POST.get("name")
 password = request.POST.get("password")
 print(name)
 print(password)
 return HttpResponse("注册成功")

url(r'^register$',ban_ip(views.register.as_view()))

class register(View):
 
 # 重写请求分发方法，as_view()的核心语句
 @method_decorator(ban_ip)
 def dispatch(self, request, *args, **kwargs):
 return super().dispatch(request, *args, **kwargs)

 def get(self,request):
 return render(request,"注册页面.html")

 def post(self,request):
 name = request.POST.get("name")
 password = request.POST.get("password")
 print(name)
 print(password)
 return HttpResponse("注册成功")

@method_decorator(ban_ip,name='get')
class register(View):

 def get(self,request):
 return render(request,"post.html")

 def post(self,request):
 title = request.POST.get("title")
 content = request.POST.get("content")
 print(title)
 print(content)
 return HttpResponse("发布成功")
