codeIgnitor正在生成数据库中的多个会话。为什么？ [英] CodeIgnitor is generating multiple sessions in the database. Why?

问题描述

我有一个网站，做页面加载一些Ajax调用。出于某种原因，codeIgnitor被插入4节（我假设为每个Ajax调用）作为加载页面。我存储会议在数据库中。

I have a site which does a few ajax calls on page load. For some reason, CodeIgnitor is inserting 4 sessions (I'm assuming one for each ajax call) as you load the page. I'm storing the sessions in the database.

我是pretty肯定应该只有每个浏览器一个会话。 Firefox的似乎只有一个生成;其他浏览器似乎创造了一大堆的会话。同一用户多个会话给我一些严重的身份验证问题。

I'm pretty sure there should only be one session per browser. Firefox seems to generate only one; other browsers seem to create a whole bunch of sessions. Multiple sessions for the same user are giving me some serious authentication problems.

这是怎么回事？我怎样才能阻止它？

Why is this happening? How can I stop it?

推荐答案

家伙

我认识的讨论是前一段时间，但有人可能会发现这个有用。
现在我用CI的会话没有存储在数据库中数据。今天，我决定试一试，并立即在同样的问题上运行：CI在每个页面加载生成新的会话

I know the discussion took place while ago, but somebody might find this useful. By now I've used CI session without storing its data in database. Today I decided to give it a try and immediately run across the same problem: CI was generating new session in every page load.

我检查了我的服务器时间，时区，我的饼干等 - 所有我能找到，因为在论坛上小费 - 没有结果。于是决定来调试CI Session类自己。
长话短说，事实证明，我的 USER_AGENT 字段在我的会话表太小了 - VARCHAR 50 - 这削减原有USER_AGENT字符串 - 因此CI没有找到我的会议，并生成onother之一。我只是增加了USER_AGENT字段大小为200，一切工作就像一个魅力。

I checked my server time, timezone, my cookie etc. - everything I could find as a tip on forums - with no result. Then decided to debug the CI Session class myself. Long story short, it turned out that my user_agent field in my session table was too small - VARCHAR 50 - which cuts the original user_agent string - hence CI doesn't find my session and generates onother one. I just increased the user_agent field size to 200 and everything works like a charm.

我忘了提，我使用的是Mac OS X Lion的。
