[SOLVED] Restful Yii Reject PUT

So I have created RESTful Yii using the class \yii\rest\ActiveController by following the tutorial from the Guide (http://www.yiiframework.com/doc-2.0/guide-rest-quick-start.html)

To enable the CORS, I add following code inside my controller class.

public function behaviors()


		$parentBehaviors = parent::behaviors();

		$cors =[

			'corsFilter' => [

				'class' => \yii\filters\Cors::className(),

				'cors'=> [

					'Origin' => ['*'],

					'Access-Control-Request-Method' => ['GET', 'POST', 'PUT','PATCH', 'DELETE', 'HEAD', 'OPTIONS'],

					'Access-Control-Request-Headers' => ['*'],

					'Access-Control-Allow-Credentials' => null,

					'Access-Control-Max-Age' => 86400,





		$newBehaviors = $cors + $parentBehaviors;

		return $newBehaviors;


I can GET, POST, DELETE to the Yii server. But somehow I can’t send PUT to the server. It says “Cross-Origin Request Blocked”. Why is that?

Apparently it has been fixed at the latest version of Yii 2.
