Question

在我的登录控制器中，我已将所有用户数据存储在会话中。我也通过打印验证了

all_userdata（）;

重定向到另一个控制器主页时会话被销毁。请帮我解决这个问题。会话数据如下。

Answer 1

这与我在 IE7 / IE8 上测试时遇到的问题相同我在这里找到了一个解决方案：http://www.philsbury.co.uk/blog/code-igniter-sessions

这是有人为第三方修复的问题，它会修补会话控制器。查看以上链接所说的内容，

的解决方案：

1）为此，您必须在 application / libraries 目录中创建一个新文件 Session.php 。
2）在新创建的文件中复制以下源代码。

<?php if (!defined('BASEPATH')) exit('No direct script access allowed'); /** * Session class using native PHP session features and hardened against session fixation. * * @package CodeIgniter * @subpackage Libraries * @category Sessions * @author Dariusz Debowczyk * @link http://www.codeigniter.com/user_guide/libraries/sessions.html */ class CI_Session { var $flash_key = 'flash'; // prefix for "flash" variables (eg. flash:new:message) function CI_Session() { $this->object =& get_instance(); log_message('debug', "Native_session Class Initialized"); $this->_sess_run(); } /** * Regenerates session id */ function regenerate_id() { // copy old session data, including its id $old_session_id = session_id(); $old_session_data = $_SESSION; // regenerate session id and store it session_regenerate_id(); $new_session_id = session_id(); // switch to the old session and destroy its storage session_id($old_session_id); session_destroy(); // switch back to the new session id and send the cookie session_id($new_session_id); session_start(); // restore the old session data into the new session $_SESSION = $old_session_data; // update the session creation time $_SESSION['regenerated'] = time(); // session_write_close() patch based on this thread // http://www.codeigniter.com/forums/viewthread/1624/ // there is a question mark ?? as to side affects // end the current session and store session data. session_write_close(); } /** * Destroys the session and erases session storage */ function destroy() { unset($_SESSION); if ( isset( $_COOKIE[session_name()] ) ) { setcookie(session_name(), '', time()-42000, '/'); } session_destroy(); } /** * Reads given session attribute value */ function userdata($item) { if($item == 'session_id'){ //added for backward-compatibility return session_id(); }else{ return ( ! isset($_SESSION[$item])) ? false : $_SESSION[$item]; } } /** * Sets session attributes to the given values */ function set_userdata($newdata = array(), $newval = '') { if (is_string($newdata)) { $newdata = array($newdata => $newval); } if (count($newdata) > 0) { foreach ($newdata as $key => $val) { $_SESSION[$key] = $val; } } } /** * Erases given session attributes */ function unset_userdata($newdata = array()) { if (is_string($newdata)) { $newdata = array($newdata => ''); } if (count($newdata) > 0) { foreach ($newdata as $key => $val) { unset($_SESSION[$key]); } } } /** * Starts up the session system for current request */ function _sess_run() { session_start(); $session_id_ttl = $this->object->config->item('sess_expiration'); if (is_numeric($session_id_ttl)) { if ($session_id_ttl > 0) { $this->session_id_ttl = $this->object->config->item('sess_expiration'); } else { $this->session_id_ttl = (60*60*24*365*2); } } // check if session id needs regeneration if ( $this->_session_id_expired() ) { // regenerate session id (session data stays the // same, but old session storage is destroyed) $this->regenerate_id(); } // delete old flashdata (from last request) $this->_flashdata_sweep(); // mark all new flashdata as old (data will be deleted before next request) $this->_flashdata_mark(); } /** * Checks if session has expired */ function _session_id_expired() { if ( !isset( $_SESSION['regenerated'] ) ) { $_SESSION['regenerated'] = time(); return false; } $expiry_time = time() - $this->session_id_ttl; if ( $_SESSION['regenerated'] <= $expiry_time ) { return true; } return false; } /** * Sets "flash" data which will be available only in next request (then it will * be deleted from session). You can use it to implement "Save succeeded" messages * after redirect. */ function set_flashdata($key, $value) { $flash_key = $this->flash_key.':new:'.$key; $this->set_userdata($flash_key, $value); } /** * Keeps existing "flash" data available to next request. */ function keep_flashdata($key) { $old_flash_key = $this->flash_key.':old:'.$key; $value = $this->userdata($old_flash_key); $new_flash_key = $this->flash_key.':new:'.$key; $this->set_userdata($new_flash_key, $value); } /** * Returns "flash" data for the given key. */ function flashdata($key) { $flash_key = $this->flash_key.':old:'.$key; return $this->userdata($flash_key); } /** * PRIVATE: Internal method - marks "flash" session attributes as 'old' */ function _flashdata_mark() { foreach ($_SESSION as $name => $value) { $parts = explode(':new:', $name); if (is_array($parts) && count($parts) == 2) { $new_name = $this->flash_key.':old:'.$parts[1]; $this->set_userdata($new_name, $value); $this->unset_userdata($name); } } } /** * PRIVATE: Internal method - removes "flash" session marked as 'old' */ function _flashdata_sweep() { foreach ($_SESSION as $name => $value) { $parts = explode(':old:', $name); if (is_array($parts) && count($parts) == 2 && $parts[0] == $this->flash_key) { $this->unset_userdata($name); } } } } ?>

3）然后加载库，

$this->load->library('session');

Answer 2

我通过在配置文件中设置此参数来解决此问题：

$config['cookie_domain']= '';

Answer 3

我已更新config.php中的以下值来解决该问题：

$config['cookie_domain'] = 'mydomain.com';   // enter your domain name

$config['cookie_secure'] = FALSE; // set "TRUE" only for https sites

Answer 4

最佳做法是使用$config['sess_driver'] = 'database'将会话存储在数据库中。

首先配置，

$config['sess_table_name'] = 'your_sessions_table';
$config['sess_driver'] = 'database';
$config['sess_cookie_name'] = 'yoursite_sessions';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

然后是cookie

$config['cookie_prefix']    = 'yourcookie';
$config['cookie_domain']    = 'cookie.domain'; //use your domain name.  For multisite configuration use '.yourdomain.com'
$config['cookie_path']      = '/';
$config['cookie_secure']    = FALSE;
$config['cookie_httponly']  = FALSE;

最后，创建一个会话表，

CREATE TABLE `your_sessions_table` (
  `id` varchar(40) NOT NULL,
  `ip_address` varchar(45) NOT NULL,
  `timestamp` bigint(20) NOT NULL DEFAULT '0',
  `data` text NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

这样，您永远不会丢失会话，直到您致电

$this->session->sess_destroy();

Answer 5

这是您拥有的Codeigniter版本。最好的方法是编辑会话的读写。打开此文件

system / libraries / Session / session.php

去第281行

ini_set('session.name', $params['cookie_name']);

通过session.id替换session.name

ini_set('session.id', $params['cookie_name']);

Answer 6

我设置了这两个选项，然后只在 Codeigniter 3.1.0 中工作

$config['cookie_domain'] = 'mydomain.com';   // enter your domain name

$config['cookie_secure'] = FALSE; // set "TRUE" only for https sites

最好的方法是编辑会话写入和读取

system/libraries/Session/session.php

转到第 281 行

ini_set('session.name', $params['cookie_name']);

用 session.id 替换 session.name

ini_set('session.id', $params['cookie_name']);

会话重定向后会在codeigniter中销毁
