Question

我最近加入了JMS Serializer包来处理数组并将其转换为JSON

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

public function searchcarAction(Request $request) 
{
    $em = $this->getDoctrine()->getManager();

   // $car = array();
    //$cars = $em->getRepository('VehicleBundle:Car')->findAll();
   // foreach ($cars as $cart) {
       // $car[] = array('id'=>$cart->getId(),'name' => $cart->getName());
   // }

    $cars = array('name' => 'john','middlename'=> 'gon');

    $serializer = $this->container->get('jms_serializer');

    $jsonGroup= $serializer->serialize($cars,'json');

    return $jsonGroup;
}
public function carAction()
{
    return $this->render('VehicleBundle:Car:car_search.html.twig');
}

car.yml

search_car:
   path: /car-search
   defaults: { _controller: "VehicleBundle:Car:searchcar" }

car_action:
  path: /search
  defaults: { _controller: "VehicleBundle:Car:car" }

JMS Serialiser在AppKernel.php中注册

这将返回500错误

控制器必须返回一个回复（{＆＃34;名称＆＃34;：＆＃34; john＆＃34;，＆＃34;中间名＆＃34;：＆＃34; gon＆＃34;}）。

  if (null === $response) {
     $msg .=' Did you forget to add a return statement somewhere in your   controller?';
  }
   throw new \LogicException($msg);
  }
  }
  return $this->filterResponse($response, $request, $type);

我的控制器出了什么问题？

模板

car_search.html.twig

 {% extends '::base.html.twig' %}

 {% block body %}

        app.config(function($interpolateProvider) {

        app.controller('customersCtrl',['$scope','$http',function($scope, $http) {

            $http.get("{{ path('search_car') }}")
            .success(function (response) {
                $scope.names= JSON.parse(response);
            });
        }]);
        //console.log(names);
    </script>

JMS序列化程序在这里不起作用吗？

Answer 1

您正在从控制器返回一个字符串而不是Response对象。

而不是：

return $jsonGroup;

您应该返回响应，例如：

return new \Symfony\Component\HttpFoundation\Response($jsonGroup, 200, ['Content-Type' => 'application/json']);

JMS Serializer无法返回响应
