我正在使用 HMVC 模块化扩展在 Codeigniter 中开发一个大型 Web 应用程序，并且在使用数据库（存储会话）时遇到会话问题。
由于我根本无法理解的原因，我的会话丢失了。
一个典型的例子是使用 Codeigniter 购物车。我可以成功地将商品添加到我的购物车中，然后在站点周围点击会话中剩余的商品。但是，当单击/暂停浏览网站约 3 分钟（不计时到秒）时，购物车会丢失所有产品并且会话是空的。查看数据库时，旧会话仍与内容一起存储在数据库中，但创建了一个新会话行（如下所示）。
我正在运行最新版本的 Codeigniter，没有对原始 Session.php 类进行扩展。
以下是我的会话配置变量：
/*
|--------------------------------------------------------------------------
| Session Variables
|--------------------------------------------------------------------------
|
| 'sess_cookie_name' = the name you want for the cookie
| 'sess_expiration' = the number of SECONDS you want the session to last.
| by default sessions last 7200 seconds (two hours). Set to zero for no expiration.
| 'sess_expire_on_close' = Whether to cause the session to expire automatically
| when the browser window is closed
| 'sess_encrypt_cookie' = Whether to encrypt the cookie
| 'sess_use_database' = Whether to save the session data to a database
| 'sess_table_name' = The name of the session database table
| 'sess_match_ip' = Whether to match the user's IP address when reading the session data
| 'sess_match_useragent' = Whether to match the User Agent when reading the session data
| 'sess_time_to_update' = how many seconds between CI refreshing Session Information
|
*/
$config['sess_cookie_name'] = 'myhmvc_session';
$config['sess_expiration'] = 7200;
$config['sess_expire_on_close'] = FALSE;
$config['sess_encrypt_cookie'] = FALSE;
$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'users_sessions';
$config['sess_match_ip'] = TRUE;
$config['sess_match_useragent'] = TRUE;
$config['sess_time_to_update'] = 300;
/*
|--------------------------------------------------------------------------
| Cookie Related Variables
|--------------------------------------------------------------------------
|
| 'cookie_prefix' = Set a prefix if you need to avoid collisions
| 'cookie_domain' = Set to .your-domain.com for site-wide cookies
| 'cookie_path' = Typically will be a forward slash
| 'cookie_secure' = Cookies will only be set if a secure HTTPS connection exists.
|
*/
$config['cookie_prefix'] = "my";
$config['cookie_domain'] = "myhmvc.co.uk";
$config['cookie_path'] = "/";
$config['cookie_secure'] = FALSE;
非常感谢任何帮助，愿意在这个阶段尝试任何事情。
