RESTfull API

Om van een model een restfull API te maken, voeg de volgende controller toe:

<?php

namespace app\controllers;

use yii\rest\ActiveController;

class ApiController extends ActiveController {
    public $modelClass = 'app\models\<Model_Naam>';
}


?>

In de browser krijg je XML terug, test via Postman en je ziet dat je JSON terug krijgt.

Of plaats zelf een controller in

class HiscoresController extends Controller
{
    /**
     * {@inheritdoc}
     */
    public function behaviors()
    {
        return [
            'verbs' => [
                'class' => VerbFilter::className(),
                'actions' => [

                ],
                'class' => '\yii\filters\Cors',
                    'cors' => [
                    'Origin' => ['*'],
                    'Access-Control-Request-Method' => ['GET', 'POST'],
                    'Access-Control-Request-Headers' => ['*'],
                ],
            ],
        ];
    }

    public static function allowedDomains()
    {
        return [
            // '*',                        // star allows all domains
            'http://localhost:3000',
            'http://test2.example.com',
        ];
    }  

    public function beforeAction($action) 
    { 
        $this->enableCsrfValidation = false; 
        return parent::beforeAction($action); 
    }
    
  	public function actionApiPost()
    { 
        Yii::$app->response->format = \yii\web\Response:: FORMAT_JSON;
        $hiscore = new Hiscores();
        $hiscore->scenario = Hiscores::SCENARIO_CREATE;
        $hiscore->attributes = yii::$app->request->post();
      	
      	if($hiscore->validate()) {
          $hiscore->save();
        } else {
           return array('status'=>false,'data'=>$hiscore->getErrors(), 'post'=>yii::$app->request->post(), 'get'=>yii::$app->request->get() );
        }
    }
  
    public function actionApiGet() {
      $sql = "select id, name, score, datetime, ip from hiscores order by score desc";
      $result = Yii::$app->db->createCommand($sql)->queryAll();
      
      return json_encode(['data'=>$result]); // of json_encode([$result);
    }
  
    public function actionIndex()
      {
      ... // hieronder de standaard code
      ...
      ...
