跨子域的代码段会话 [英] Codeigniter sessions across sub domains

问题描述

我有多个子网域，我想使用跨子网域的工作阶段。

I have multiple subdomains and i'm trying to use the sessions across subdomains.

http://example.com
http://subdomain.example.com

config.php

I have also set the cookie domain in config.php

$config['cookie_domain'] = ".example.com";

会话userdata和flashdata在其他域中使用时为空。 Im使用相同的会话表以及CI实例

The session userdata and also flashdata are empty when used in the other domain. Im using the same session table as well for both CI instance

推荐答案

从以下解决方案：分享会话

cookie_domain和cookie前缀必须设置

Both the cookie_domain and cookie prefix has to be set

$config['cookie_domain'] = ".example.com";
$config['cookie_prefix'] = "example_";
