 /**
  * This method is used to valide the user's authority with token.
  * This method is invoked right before an action is executed.
  *
  * The method will trigger the [[EVENT_BEFORE_ACTION]] event. The return value of the method
  * will determine whether the action should continue to run.
  *
  * If you override this method, your code should look like the following:
  *
  * ```php
  * public function beforeAction($action)
  * {
  *     if (parent::beforeAction($action)) {
  *         // your custom code here
  *         return true;  // or false if needed
  *     } else {
  *         return false;
  *     }
  * }
  * ```
  *
  * @param Action $action the action to be executed.
  * @return boolean whether the action should continue to run.
