没有在 FosRest 嵌套控制器中注入 Symfony 请求对象答案

【问题标题】：Symfony Request Object not being Injected in FosRest nested controller没有在 FosRest 嵌套控制器中注入 Symfony 请求对象

【问题描述】：

我在控制器中指定时遇到 Symphony 未注入 Request 对象的问题，我的代码如下：

Routing.yml：

user:
  type: rest
  resource: AppBundle\Controller\UserController

user_comments:
  type: rest
  parent: user
  resource: AppBundle\Controller\UserCommentsController

和 FosRest 控制器

namespace AppBundle\Controller;

use Symfony\Component\HttpFoundation\Request;

class UserCommentsController extends BaseRestController
{

    public function postCommentAction(Request $request, $userId)
    {
        var_dump($request);

        return $this->view($userId, 201);
    }

我的应用根本不响应路由，但是当我从 postCommentAction 中删除 Request $request 时，它按预期工作（但显然我无权访问 Request 对象）。

【问题讨论】：

你的app/logs/dev.log有什么东西吗？
除了一些 event.debugs 真的没有别的了 - 我已经更新了日志问题，看不到任何异常，也没有可见的错误。
您的常规 PHP 或虚拟主机日志中有什么信息吗？
能否请您发布控制器的 yaml/xml 定义？

【解决方案1】：

对不起大家 - 问题是由 var_dump($request) 引起的 - 一个隐藏在 VM 中的基本内存问题，考虑到 PHP 可以访问 ~512mb 内存，这令人印象深刻。
