restful 用postman测试put和patch接收到的数据格式有问题 [ 2.0 版本 ]

我用 用postman测试put和patch 返回\Yii::$app->request->post()的数据是

{
    "status": 1,
    "message": "success",
    "data": {
        "------WebKitFormBoundaryQAdeVNHjsT4k9EZD\r\nContent-Disposition:_form-data;_name": "\"name\"\r\n\r\nrestrrrrrrrtttttt\r\n------WebKitFormBoundaryQAdeVNHjsT4k9EZD--\r\n"
    }
}

我的服务端代码是这样的

public function actionUpdate($id)
{
    $model = $this->findModel($id);
    $model->attributes = \Yii::$app->request->post();
    $model->save(false);
    return \Yii::$app->request->post();
    //return $model;
}

protected function findModel($id)
{
    $modelClass = $this->modelClass;
    $model = $modelClass::findOne($id);
    if ($model !== null) {
        return $model;
    } else {
        throw new NotFoundHttpException('信息不存在');
    }
}
