自定义行为

class MyBehavior extends ActionFilter    
{                                        
    private $_prop2;                     
    public  $pro1;                       
    protected $c;                        

    public function getProp2()           
    {                                    
        return $this->_prop2;            
    }                                    

    public function setProp2($value)     
    {                                    
        $this->_prop2 = $value;          
    }                                    

    public function beforeAction($action)
    {                                    
        var_dump(111);                   
        return true;                     
    }                                    

    public function isGuest()            
    {                                    
        return Yii::$app->user->isGuest; 
    }   
}   

控制器

public function behaviors()
{
        return [
                'myBehavior'=> MyBehavior::className(),
                'verbs'=>[
                        'class'=>VerbFilter::className(),
                        'actions'=>[
                                'delete' => ['POST'],
                        ],
                ]
        ];
}

beforeaciton 方法的确可以被调用，但是行为下的公共方法无法被调用
