14           
15 @method_decorator(auth, name='dispatch')        #也可以写到类上, 这样在get,post请求都可以省略， 也可以写在类里面方法上
16 class Order(views.View):
17     #@method_decorator(auth)
18     #def dispatch(self, request, *args, **kwargs):
19         #return  super(Order, self).dispatch(request, *args, **kwargs)
20                
21     #@method_decorator(auth):    #只对get请求有效

23          v = request.COOKIE.get('username')
24         return render(request, 'index.html', {'current_user': v })
