推荐答案

这很简单，但你必须编写代码，没有内置 - 在做的方式。例如，您可以这样做的一种方法是将到期时间加密到查询字符串中，然后在页面中解析它并与服务器时间进行比较。

It's very easy but you have to write code, there is no built-in way to do it. For example, one way you can do it is to encrypt the expiration time into the querystring and then parse that in your page and compare to the server time.
