在 php 中的子域上共享会话 [英] Share session on subdomains in php

问题描述

我在两个子域之间共享会话时遇到问题，我在这里和其他地方阅读了很多主题.

I have a problem sharing the session between two subdomains, and I've read a lot of threads here and other places.

我有 www.xx.com 和 sub.xx.com 并且我已经设置了

I have www.xx.com and sub.xx.com and I've set

session_name("PHPSESSXX");
session_set_cookie_params(0, '/', '.xx.com');

并且 session.save_path 在两个域上是相同的.

and the session.save_path is the same on both domains.

我在两个域上都有一个名为 PHPSESSXX 的 cookie，它具有相同的值.

I get a cookie called PHPSESSXX on both domains, and it has the same value.

当我登录 www.xx.com 时，我会收到一个会话，其中包含一些详细信息，并且在我转到 sub.xx.com 之前一直保持这种状态.然后 sub.xx.com 上的会话是空的，如果我刷新 www.xx.com，那里的会话也消失了.所以它做了一些事情，但似乎每次我访问不同的子域时都会覆盖会话数据.

When I log on to www.xx.com I get a session with some details in it, and it stays that way until I go to sub.xx.com. Then the session on sub.xx.com is empty, and if I refresh www.xx.com, the session there is gone as well. So it does something, but it seems to be overwriting the session data each time I visit a different subdomain.

任何人有任何想法吗?- 我可以以某种方式调试它吗?

Any ideas anyone? - Can i debug this somehow?

顺便说一句:我在两个域上都使用 ssl.

Btw: I'm using ssl on both domains.

干杯

推荐答案

我的解决方案是在 .htaccess 中设置一个标志，如下所示:

My solution was to set a flag in .htaccess like this:

php_flag "suhosin.session.cryptdocroot" 0

它现在完美运行;o)

问题是系统上安装了Suhosin，和ini变量

The problem was that Suhosin was installed on the system, and the ini variable

suhosin.session.cryptdocroot = On

以这样一种方式加密会话文件，当另一个子域试图更改会话时，出于安全原因，它会删除所有内容.

encrypted the session files in such a way, that when a different subdomain tried to change the session, it deleted everything for security reasons.

在 ini 文件中将变量设置为 Off 或 [nothing] 对我不起作用，尽管我可能没有找到正确的文件.

It didn't work for me to set the variable to Off or [nothing] in the ini-file, though maybe I didn't find the right file.

我也尝试在 PHP 中设置它，但没有任何运气.像这样:

I also tried setting it in PHP without any luck. Like this:

ini_set('suhosin.session.cryptdocroot', 0)

干杯
