CodeIgniter扩展用户的会话过期时间 [英] CodeIgniter extend user's session expiration time

问题描述

可以在CI中扩展用户的会话过期时间。我想要做的是，默认情况下，每个用户的会话cookie持续例如1天，但每次用户访问该网站，他的会话过期时间延长一天。

Is it possible to extend user's session expiration time in CI. What I want to do is, by default every user's session cookie lasts for example 1 day, but every time user visits the site his session expiration time is extended by one more day.

我不知道这是否是一个好主意，也许我应该设置cookie的生命时间为一个星期，这是吗？

I don't know if it is a good idea to do this, maybe I should just set cookies life time for like a week and that's it?

推荐答案

我相信你想要的实际上是默认行为。
查看/system/libraries/Session.php中的sess_read（）和sess_update（）

I believe what you want is actually the default behavior. Take a look at sess_read() and sess_update() in /system/libraries/Session.php

last_activity为活动会话每五分钟更新一次。

last_activity for an active session is updated every five minutes.

使用last_activity + sess_expiration检查会话到期日期<现在

Session expiration is checked with last_activity + sess_expiration < now

所以，对于你想要的行为，只需将你的sess_expiration时间设置为86400（一天），你应该都设置。

So, for the behavior you want, just set your sess_expiration time to 86400 (one day), and you should be all set.
