从Symfony中的控制器返回Json响应

Question

I am trying return a JSON response from a controller in Symfony 3.4

This is my controller:

/**
     * @Route("/message/board/post", name = "message_post")
     * @Method("POST")
     */
    public function postMeg(Request $request)
    {
        $entityManager = $this->getDoctrine()->getEntityManager();
        $message = new message($request->request->get("txtName"));
        $message->setMes($request->request->get("txtMes"));
        $entityManager->persist($message);
        $entityManager->flush();
        return new JsonResponse(['result' => 'ok', 'ret' => array($entityManager)]);
    }

But I get {"result":"ok","ret":[{}]} as Response in the browser

I hope it can show like ['result' => 'ok', 'ret' => txtName, txtMes ]

You should use $message instead of $entityManager as mentioned in the comments but passing the entity to new JsonResponse() will only include public properties from the message entity and they are usually all private . There are many ways to do this, but the easiest is just to insert exactly what you want with the entity's getters:

return new JsonResponse([
  'result' => 'ok',
  'ret' => [
    'txtName' => $message->getTxtName(),
    'txtMes ' => $message->getTxtMes(),

  ],
]);
