Rest Api on yii2 in Json format?

Question

Yii

I decided to make within the site, the controller responsible for the rest of the action.
How can I reduce all answers to one format that would simply return data and without unnecessary information, but within one controller. Current way

public function behaviors()
    {
       $behaviors = parent::behaviors();
       $behaviors['authenticator'] = [
            'class' => QueryParamAuth::className(),
       ];
        $behaviors['contentNegotiator']['formats']['text/html'] = Response::FORMAT_JSON;
        return $behaviors;
    }

I got this result, which is redundant information for the user

{"name":"Unauthorized","message":"You are requesting with an invalid credential.","code":0,"status":401,"type":"yii\\web\\UnauthorizedHttpException"}

How can I, within only one controller, fully control the output of errors, but not touch the rest of the project?

Answer 1

Try to put YII_DEBUG = false in the index file.
You can still try to do as it is written here , but this is for all controllers at once.

Answer 2

public $serializer ='frontend\modules\v2\component\CustomSerializer',

    public function actionSpecialFoApi()
    {

     if(rest_responce == true) {
        /** @var \frontend\modules\v2\component\ApicoSerializer $serializer */
        return Yii::createObject($this->serializer)->serialize($data);
        return; //возможно это может надо???
    }
}

It says
yii\rest\Serializer
Serializes the given data into a format that can be easily turned into other formats.
You may override this method to support more object types.
The code has not been tested, sorry)
