How to make a selection from the database in yii2 using the rest api?

Question

Yii

I use ActiveController as written in the documentation.

public function actionIndex()
    {
        $modelClass = $this->modelClass;        
        $developer = Developers::findOne([
            'id' => Yii::$app->request->get('developer_id'),
        ]);
        $complex_type = ComplexType::findOne([
            'id' => Yii::$app->request->get('complex_id'),
        ]);
        $complex = Complex::findOne([
            'type_id' => $complex_type->id,
            'developer_id' => $developer->id,
        ]);
        $query = $modelClass::find()
        ->where(
            [
                'amount_room' => Yii::$app->request->get('amount_room'),
                'yardage' => Yii::$app->request->get('yardage'),
                'level' => Yii::$app->request->get('level'),
                'complex_id' => $complex->id,
            ]);
        return new ActiveDataProvider([
            'query' => $query,
        ]);
    }

The question is: Now it is necessary to transfer all the parameters, which is logical in principle. How to make a check for the fullness of the parameter, and already, depending on this, do the search? I can do a bunch of if's, but it doesn't turn out very pretty. What is the best way to implement this?
