如何在yii2型号上添加过滤器

namespace app\filters;

use yii\base\ActionFilter;

class MyFilter extends ActionFilter
{
    public function beforeAction($action)
    {
        // 在执行操作之前调用的逻辑
        return parent::beforeAction($action);
    }

    public function afterAction($action, $result)
    {
        // 在执行操作之后调用的逻辑
        return parent::afterAction($action, $result);
    }
}

use app\filters\MyFilter;

class MyController extends \yii\web\Controller
{
    public function behaviors()
    {
        return [
            'myFilter' => [
                'class' => MyFilter::class,
                'only' => ['index'], // 仅对index操作应用过滤器
            ],
        ];
    }

    // 控制器操作
    public function actionIndex()
    {
        // ...
    }
}
