Question

我有一个为cakephp3开发的插件，在我的组件里面我想读取存储在会话中的值。

在cakephp 2中，我用过：

$userId = CakeSession::read('Auth.User.id');

但如果我将它用于cakephp 3，请将此错误告诉我：

Error: Call to undefined method UserPermissions\Controller\Component\UserPermissionsComponent::_hasSession() 
File /Users/info/Sites/cakephp3/vendor/cakephp/cakephp/src/Network/Session.php 
Line: 382

使用以下内容在组件I中包含会话：

use Cake\Network\Session;

如何在会话中读取值？感谢

我会在你的initialize()方法中实现这一点：

use Cake\Controller\Component;
use Cake\Controller\ComponentRegistry;

class YourComponent extends Component{

    public $controller = null;
    public $session = null;

    public function initialize(array $config)
    {
        parent::initialize($config);
        // ....

        /**
         * Get current controller
        */
        $this->controller = $this->_registry->getController();

        $this->session = $this->controller->request->session();

        // You can then use $this->session in any other methods        
        // If debug = true else use print_r() to test
        debug($this->session->read('Auth.User.id')); 
    }        
}
