Question

我对Yii2很新。我创建了一个前端Yii2应用程序，现在我想定义一个每晚都会调用一些动作的cronjob。

我为此创建了一个简单的控制台应用程序，按照此处的教程：https://www.yiiframework.com/wiki/646/how-to-implement-cron-in-yii-2，使用以下代码：

namespace console\controllers;

use yii\console\Controller;

class CronController extends Controller {
    public function actionIndex() {
        echo "cron service runnning";
    }
}

我尝试通过运行它来调用它：

php yii cron/index

但是我收到以下错误：

    Exception 'yii\base\InvalidConfigException' with message 'Failed to instantiate component or class "user".'

in /var/www/html/my-yii2-app/vendor/yiisoft/yii2/di/Instance.php:139

我不知道会出现什么问题。

//if guest user access site so, redirect to login page.
'as beforeRequest' => [  
    'class' => 'yii\filters\AccessControl',
    'rules' => [
        [
            'actions' => ['login', 'error'],
            'allow' => true,
        ],
        [
            'allow' => true,
            'roles' => ['@'],
        ],
    ],
],

这部分配置是个问题。 AccessControl在控制台应用程序配置中没有任何意义（控制台应用程序没有Yii:$app->user）。由于您在公共配置中进行了设置，因此它也可用于控制台应用程序的配置。

您应该将此设置移至更高级别，可能移至frontend/config/main.php和backend/config/main.php，因此它仅用于Web应用程序。

Yii2控制台应用程序错误＆＃39;无法实例化组件或类＆＃34;用户＆＃34;。＆＃39;
