Yii2中的ForbiddenHttpException问题

Question

我尝试在控制器中执行这段代码。

throw new ForbiddenHttpException();

我期望看到403错误，但我看到以下错误：

An Error occurred while handling another error:
yii\web\ForbiddenHttpException: You are not allowed to perform this action. in C:\xampp\htdocs\university\vendor\yiisoft\yii2\filters\AccessControl.php:158

我想你忘了在访问规则中添加错误操作的规则，你可以在行为中使用下面的代码：

  [
       'actions' => ['error'],
       'allow' => true,
       'roles' => ["?","@"],
  ],

或者在访问规则中，对您需要权限的操作使用only
