试图JSON编码和接收400: Bad Request在yii2.我试图在Rest客户端编码,但它无法正常工作.

<?php 
    namespace app\controllers;
    use Yii;
    use yii\filters\AccessControl;
    use yii\web\Controller;
    use yii\filters\VerbFilter;
    use app\models\TblUserRegistration;
    class UserController extends Controller
    {
        public function actionRegister()
        {
            $model = new TblUserRegistration();
            $username = $_POST['username'];
            echo json_encode($username);
        }
    }
?>
