无法在Yii2中从系统注销

Question

我想从系统＆amp;我在下面写了代码：

public function behaviors()
{
    return [
        'access' => [
            'class' => AccessControl::className(),
            'only' => ['signin', 'logout', 'register', 'index'],
            'rules' => [
                [
                    'allow' => true,
                    'actions' => ['index', 'signin', 'register'],
                    'roles' => ['?'],
                ],
                [
                    'allow' => true,
                    'actions' => ['logout'],
                    'roles' => ['@'],
                ],
            ],
//                'rules' => [
//                    [
//                        'allow' => true,
//                        'actions' => ['logout'],
//                        'roles' => ['@'],
//                    ],
//                    [
//                        'actions' => ['update', 'profile', 'delete', 'all', 'add'],
//                        'allow' => true,
//                        'verbs' => ['GET', 'POST'],
//                        'roles' => ['@'],
//                    ],
//                    [
//                        'actions' => ['signin', 'register'],
//                        'allow' => true,
//                        'roles' => ['?'], // guests
//                        'verbs' => ['GET', 'POST'],
//                    ],
//                    [
//                        'actions' => ['index'],
//                        'allow' => true,
//                        'verbs' => ['GET', 'POST'],
//                        'roles' => ['?'],
//                    ],
//                ],
            'denyCallback' => function ($rule, $action) {
                throw new \Exception('You are not allowed to access this page');
////                    $this->redirect(['daxilol']);
            },
        ],
        'verbs' => [
            'class' => VerbFilter::className(),
            'actions' => [
                'logout' => ['POST', 'PUT'],
            ],
        ],
    ];
}

如您所见，我尝试了太多方法让用户退出。但在我的每次尝试中它都会返回：

  

异常

     

您无权访问此页面

我做错了什么？

尝试避免顶部的唯一条款

   public function behaviors()
{
    return [
        'access' => [
            'class' => AccessControl::className(),
            'rules' => [
               [
                  'allow' => true,
                  'actions' => ['index', 'signin', 'register'],
                  'roles' => ['?'],
              ],
              [
                  'allow' => true,
                  'actions' => ['logout'],
                  'roles' => ['@'],
              ],
              [
                  'allow' => false,
                  'actions' => ['register'],
                  'roles' => ['@'],
              ],
            ],
        ],
