我正在使用codeigniter
配置ion_auth
,MySQL作为后端,
我的应用程序运行顺利,但有时/不随机,当我调用add/update
函数时,它会自动将我注销。
我正在研究它最近1个月但到目前为止找不到解决方案?
我还更改了ion_auth
配置文件中的设置。
$config['user_expire'] = 0;
任何想法,解决这个问题?
请评论,以便我可以在需要时提供更多数据。
注意:我还检查this但没有运气。

您可能正在执行ajax请求,这是一个常见问题......
我建议您使用会话数据库并使ajax调用不更新会话...
在会话课上进行此操作
class MY_Session extends CI_Session {
public function sess_update()
{
$CI =& get_instance();
if ( ! $CI->input->is_ajax_request())
{
parent::sess_update();
}
}
}

使用您自己的MY_Session.php
库创建一个会话库,该库使用仅在不是AJAX请求时执行更新方法的sess_update
方法覆盖:
<强> MY_Session.php 强>
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
require_once BASEPATH . '/libraries/Session.php';
class MY_Session extends CI_Session
{
function __construct()
{
parent::__construct();
$this->CI->session = $this;
}
function sess_update()
{
// Do NOT update an existing session on AJAX calls.
if (!$this->CI->input->is_ajax_request())
return parent::sess_update();
}
}
档案位置:
/application/libraries/MY_Session.php * /
您可以从config/autoload.php:
$autoload['libraries'] = array( 'MY_Session');
或者,您可以稍后加载:
$this->load->library('MY_Session');
这是什么sess_update();确实吗
在system/libraries/Session.php
中,function sess_update()
会自动更新您的上一个活动。此功能默认情况下每五分钟更新一次会话。
public function sess_update()
{
// We only update the session every five minutes by default
if (($this->userdata['last_activity'] + $this->sess_time_to_update) >= $this->now)
{
return;
}
// _set_cookie() will handle this for us if we aren't using database sessions
// by pushing all userdata to the cookie.
$cookie_data = NULL;
/* Changing the session ID during an AJAX call causes problems,
* so we'll only update our last_activity
*/
if ($this->CI->input->is_ajax_request())
{
$this->userdata['last_activity'] = $this->now;
// Update the session ID and last_activity field in the DB if needed
if ($this->sess_use_database === TRUE)
{
// set cookie explicitly to only have our session data
$cookie_data = array();
foreach (array('session_id','ip_address','user_agent','last_activity') as $val)
{
$cookie_data[$val] = $this->userdata[$val];
}
$this->CI->db->query($this->CI->db->update_string($this->sess_table_name,
array('last_activity' => $this->userdata['last_activity']),
array('session_id' => $this->userdata['session_id'])));
}
return $this->_set_cookie($cookie_data);
}
// Save the old session id so we know which record to
// update in the database if we need it
$old_sessid = $this->userdata['session_id'];
$new_sessid = '';
do
{
$new_sessid .= mt_rand(0, mt_getrandmax());
}
while (strlen($new_sessid) < 32);
// To make the session ID even more secure we'll combine it with the user's IP
$new_sessid .= $this->CI->input->ip_address();
// Turn it into a hash and update the session data array
$this->userdata['session_id'] = $new_sessid = md5(uniqid($new_sessid, TRUE));
$this->userdata['last_activity'] = $this->now;
// Update the session ID and last_activity field in the DB if needed
if ($this->sess_use_database === TRUE)
{
// set cookie explicitly to only have our session data
$cookie_data = array();
foreach (array('session_id','ip_address','user_agent','last_activity') as $val)
{
$cookie_data[$val] = $this->userdata[$val];
}
$this->CI->db->query($this->CI->db->update_string($this->sess_table_name, array('last_activity' => $this->now, 'session_id' => $new_sessid), array('session_id' => $old_sessid)));
}
// Write the cookie
$this->_set_cookie($cookie_data);
}

替换system / libraries / Session.php中的第346行(函数sess_update())
if (($this->userdata['last_activity'] + $this->sess_time_to_update) >= $this->now)
使用:
if (($this->userdata['last_activity'] + $this->sess_time_to_update) >= $this->now || $this->CI->input->is_ajax_request())
希望这适合你。

这是最好的答案。
codeignter controller
function fetchSendToProduction($sku,$old_fab_id)
{
if($this->input->is_ajax_request() > 0)
{
$result = $this->ifmodel->fetchSendToProduction($sku,$old_fab_id);
echo json_encode($result);
}
}
codeignter view ajax call
$.ajax({
type: "POST",
url: "<?php echo base_url(); ?>index.php/inputFactor/fetchSendToProduction/" + sku+'/'+old_fab_id ,
cache: false,
processData: false,
success: function(data)
{
}
});
