decorators =[tt,] #这个是给 我们的响应添加装饰器
def dispatch_request(self):
return "ojbk"
app.add_url_rule("/index",view_func=Index.as_view(name="index"),endpoint="index1")
# 为什么要给as_view传递name= "index",
#1 as_view再语法就要你传，
#2 他作用Index.as_view(name="index")他返回是的view这个函数对象，我们传递name="index"是给view的__name__改变名字。如果不传，我没有办法通过名字来找路由的映射关系，因为都是”view“
