在 appcontroller 中编写 cakephp 会话

Question

我有一个要在所有页面上运行的访问者日志记录脚本
所以我把它保存在 appController 的 beforeFilter 方法中，如下所示

public function beforeFilter() { 
    //log visitors starts here
    if( $this->Session->check('visited') == true )
    {
        //logging code
    }
    else
    {
        $this->Session->write('visited') = true;  //this line gives error
    }
    //log visitors ends here
}

我收到以下错误

 Fatal error: Class declarations may not be nested in D:\wamp\www\myproject\lib\Cake\Error\ExceptionRenderer.php on line 54

通过注释如下所示的会话编写行，页面运行时不会出现 ant 错误

$this->Session->write('visited') = true;    

我也将此代码更改为 afterFilter 和 beforeRender 方法，但仍然错误

Answer 1

您可以改用 CakeSession：

public function beforeFilter() { 
    if( CakeSession::check('visited') ){
        //logging code
    } else {
        CakeSession::write('visited', true);
    }
}

根据文档：http://book.cakephp.org/2.0/en/core-libraries/components/sessions.html#SessionComponent::write

public function beforeFilter() { 
    //log visitors starts here
    if( $this->Session->check('visited') ) // No need to check == true
    {
        //logging code
    }
    else
    {
        $this->Session->write('visited', true);  //Second param to set the value
    }
    //log visitors ends here
}
