Set
放
\Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
in the controller's action somewhere before return.
在控制器之前某处的动作中return。

Simply Add this in controller
只需在控制器中添加它
public function beforeAction($action)
{
\Yii::$app->response->format = Response::FORMAT_JSON;
return parent::beforeAction($action);
}

use yii\helpers\Json;
use yii\web\Response;
Firstly include the 2 lines above at the top of your controller, then in any of your Controller actions, just before the return statements, include the below
首先在您的控制器顶部包含上面的 2 行，然后在您的任何控制器操作中，就在 return 语句之前，包含以下内容
Yii::$app->response->format = Response::FORMAT_JSON;
return Json::encode([
'message' => 'success'
]);
You can build the return array as you deem fit.
您可以根据需要构建返回数组。
