    public function actions()
    {
        $actions = parent::actions();
        unset($actions['index']);
        return $actions;
    }

    function actionIndex(){
        $modelClass = $this->modelClass;
        return new ActiveDataProvider([
            'query'=>$modelClass::find()->asArray(),
            'pagination' => ['pageSize'=>5],

use common\models\Article;
use yii\db\Query;
use yii\rest\ActiveController;
use yii\rest\Controller;

class TopController extends Controller
{

    public function actionIndex()
    {
        $all = Article::find()
            ->select([
                '序号' => 'article.id',
                '标题' => 'article.title',
                '状态' => 'article.status',
                '作者' => 'user.username'])
            ->leftjoin('user', 'user.id=article.created_by')
            ->orderBy('序号 desc')
            ->limit(5)
            ->asArray();



//        echo $all->createCommand()->getRawSql() . "\n";


//        $all = (new Query())
//            ->select(['article.id', 'article.title', 'user.username'])
//            ->from(['article', 'user'])
//            ->where('article.created_by=user.id')
//            ->orderBy('article.id desc')
//            ->limit(5);
//
//        echo $all->createCommand()->getRawSql() . "\n";


        return $all->all();
    }

}

If the function does not return data, and the data can sql statement, call asArray()the method
