小编iRE*_*ful的帖子

所以,这是我刚刚建立的控制器:

namespace MDP\API\ImageBundle\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\JsonResponse;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;

class RetrieverController {

    private $jsonResponse;

    private $request;

    public function __construct(JsonResponse $jsonResponse, Request $request) {
        $this->jsonResponse = $jsonResponse;
        $this->request = $request;
    }

    /**
     * @Route("/image/{amount}")
     * @Template("MDPAPIImageBundle:Retriever:index.json.twig")
     */
    public function retrieve($amount)
    {
    }
}

我想让这个控制器作为服务工作,使用DependencyInjection.所以,这是我的services.xml文件:

<?xml version="1.0" ?>

<container xmlns="http://symfony.com/schema/dic/services"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">


    <services>
        <service id="mdpapi_image.json_response" class="Symfony\Component\HttpFoundation\JsonResponse" />
        <service id="mdpapi_image.request" class="Symfony\Component\HttpFoundation\Request" />
        <service id="mdpapi_image.controller.retriever" class="MDP\API\ImageBundle\Controller\RetrieverController">
            <argument type="service" id="mdpapi_image.json_response" />
            <argument type="service" id="mdpapi_image.request" />
        </service>
    </services>
</container>

但是,当我尝试执行我的控制器时,我总是得到这个异常:

可捕获致命错误:传递给MDP\API\ImageBundle\Controller\RetrieverController …
