Question

我正在尝试更改默认会话超时值。在我的控制器中我做到了：

  public function beforeAction($action) {
    $session = new CHttpSession;
    $timeout = $session->getTimeout();
    if ($timeout != 10) {
      $session->setTimeout(10);
    }
    return true;
  }

但我的会话永远不会超时，即使在非活动状态10秒后我也可以访问该页面。

我也尝试通过会话组件进行配置，如下所示：

   'session' => array(
            'sessionName' => SITE_SESSION_COOKIE_NAME,
            'class' => 'CHttpSession',
            'timeout' => 10
        ),

但结果相同。会话剂量超时！我错过了什么吗？

Answer 1

class数组中的session显然应为CDbHttpSession才能生效。有关类似问题，请参阅here。

尝试在配置中关闭自动启动会话：

'session' => array(
        'sessionName' => SITE_SESSION_COOKIE_NAME,
        'class' => 'CHttpSession',
        'autoStart' => false
    ),

在这种情况下，您需要手动启动会话：Yii::app()->session->open()，但在改善使用寿命之前，请尝试执行以下操作：

Yii::app()->session->open($session_lifetime);
$cook_p = Yii::app()->session->getCookieParams();
$cook_p['lifetime'] = $session_lifetime;
Yii::app()->session->setCookieParams($cook_p);

或者您可以使用新参数lifetime继承CHttpSession并在方法init()中执行此操作：

class MyHttpSession extends CHttpSession{
   public $lifetime = false;
   public function init()
   {
      if($this->lifetime !== false){
          $cook_p = $this->getCookieParams();
          $cook_p['lifetime'] = $this->lifetime;
          $this->setCookieParams($cook_p);
          $this->setTimeout($this->lifetime);
      }
      parent::init();
   }

}

并在配置中：

'session' => array(
        'sessionName' => SITE_SESSION_COOKIE_NAME,
        'class' => 'MyHttpSession',
        'lifetime' => 60 // 1 minute
    ),

基于用户在30分钟内处于活动状态的会话超时，在配置中：

'components'=>array(
        'user'=>array(
            // enable cookie-based authentication
            'allowAutoLogin'=> true,
            'autoRenewCookie'=> true,
            'authTimeout' => 1800
        ),
        'session' => array(
                    'class' => 'FrontCHttpSession',
                    'savePath' => dirname(__FILE__),
                    'cookieMode' => 'allow',
                    'cookieParams' => array(
                            'path' => '/',
                            'domain' => 'mydomain.com',
                            'httpOnly' => true,
                            'lifetime' => 1800
                    ),
                    'timeout' => 1800
        ),

扩展会话类，类似的想法可以用于CDbHttpSession

<?php

class FrontCHttpSession extends CHttpSession
{

      /*default is 0 which means the cookie lifetime will last as long as the browser is open*/
      private $_clientLifetime;
      /*time in seconds how long the session should remain open after user in-activity*/
      private $_sessionTimeout;
      /*cookie params defined in config*/
      private $_cookieParams;

      /**
      * Starts the session if it has not started yet.
      */

      public function open()
      {

            $this->_cookieParams = $this->getCookieParams();
            $this->_clientLifetime = $this->_cookieParams['lifetime'];
            $this->_sessionTimeout = $this->timeout;

            if($this->getUseCustomStorage())
                  @session_set_save_handler(array($this,'openSession'),
                        array($this,'closeSession'),
                        array($this,'readSession'),
                        array($this,'writeSession'),
                        array($this,'destroySession'),
                        array($this,'gcSession'));

            //session is already started, check if session has been not been active longer than timeout     
            if (session_id() != '')
            {
                  if ($this->get('last_active') < time() - $this->_sessionTimeout)
                  {
                      $this->destroy();
                  }
                  else if ($this->_clientLifetime > 0)
                  {
                      $this->updateSessionCookieExpire();
                  }
            }

            @session_set_cookie_params($this->_clientLifetime, array($this->_cookieParams['path'], 
                  $this->_cookieParams['domain'], $this->_cookieParams['secure'], $this->_cookieParams['httpOnly']));

            @session_start();
            $this->add('last_active', time());

            if(YII_DEBUG && session_id()=='')
            {

                  $message=Yii::t('yii','Failed to start session.');

                  if(function_exists('error_get_last'))

                  {

                        $error=error_get_last();

                        if(isset($error['message']))

                              $message=$error['message'];

                  }

                  Yii::log($message, CLogger::LEVEL_WARNING, 'system.web.CHttpSession');

            }

      }

      public function updateSessionCookieExpire() 
      {
            if (isset(Yii::app()->request->cookies[$this->getSessionName()])) 
            {
                  $c = Yii::app()->request->cookies[$this->getSessionName()]; 
                  $c->expire = time() + $this->_clientLifetime;
                  $c->path = $this->_cookieParams['path'];
                  $c->domain = $this->_cookieParams['domain'];
                  $c->httpOnly = $this->_cookieParams['httponly'];
                  $c->secure = $this->_cookieParams['secure'];
                  Yii::app()->request->cookies[$this->getSessionName()] = $c;
            }
      }

}

Yii Session没有过来
