You can't, unless you store it elsewhere with your own mechanisms. Epxiry is a write-only field for cookies. Only the name and value of a cookie can be read once set. If the cookie is readable, it's not expired--that's all you get to know about that.
你不能,除非你用自己的机制存储在别处。 Epxiry是cookie的只写字段。设置后,只能读取cookie的名称和值。如果cookie是可读的,它就没有过期 - 这就是你所了解的全部内容。

You cannot read the cookie expiry time, because browsers do not send it to your server, only the value of cookies. Browsers send cookies back to the server in a HTTP header like this;
您无法读取Cookie到期时间,因为浏览器不会将其发送到您的服务器,只会发送cookie的值。浏览器在这样的HTTP头中将cookie发送回服务器;
Cookie: cookieName=cookieValue
The most common method of preventing cookies from expiring is setting an expiry date way in the future.
阻止cookie过期的最常用方法是在将来设置到期日期。
