yii2.0在运行http://localhost/~name/yii2hello/backend/web/index.php时发出403错误？r = site/say

Question

我是yii的新手.我很难设置yii2.0高级并试图运行简单的hello程序.

我在后端/ Controllers/SiteController.php中添加了以下代码

public function actionSay($message = 'Hello')
{
    return $this->render('say',['message' => $message]);
}

然后,我使用以下代码在backend/views/site /中创建了say.php文件

<?php
    use yii\helpers\Html;
?>
<?= Html::encode($message) ?>

我输入../yii2hello/backend/web/index.php?r=site/say&message=Hello+World浏览器来访问该页面.

我收到了403错误 "you are not allowed to perform this action."

谁能告诉我问题出在哪里？

如果未定义访问此操作的权限,则会发生此错误.
您必须为您的操作添加权限,如下所示:

public function behaviors()
{
    return [
        'access' => [
            'class' => AccessControl::className(),
            'rules' => [
                [
                    'actions' => ['say'],
                    'allow' => true,
                ],
            ],
        ]
    ];
}
