更新 Symfony 2.4:“渲染片段只能在处理请求时完成." [英] Updating Symfony 2.4 : "Rendering a fragment can only be done when handling a Request."

问题描述

自从我迁移到 Symfony 2.4 后，我收到以下错误消息:

Since I migrated to Symfony 2.4, I'm getting the following error message :

渲染片段只能在处理请求时完成.

Rendering a fragment can only be done when handling a Request.

发生这种情况是因为，在某些页面上，我通过执行 $sf2->container->get('twig') 在由另一个旧框架处理的某些页面中使用 Twig 呈现一些模板->render("MyBundle::my-template.html.twig");.

It's happening because, on some pages, I'm rendering some templates with Twig inside some pages which are handled by another older framework, by doing $sf2->container->get('twig')->render("MyBundle::my-template.html.twig");.

是的，Symfony 2 没有处理这些请求是对的，但我仍然想用 Twig 渲染这些模板！为什么我不能(再)那样做?！以及如何解决这个问题?

So yes, that's right that Symfony 2 isn't handling those requests, but I still want to render those templates with Twig ! Why can't I do that (anymore) ?! And how to fix that ?

这是我在旧项目中执行以启动"SF2的代码:

Here is the code I'm executing to "boot" SF2 in my older project :

$loader = require_once __DIR__.'/../../../app/bootstrap.php.cache';
Debug::enable();
require_once __DIR__.'/../../../app/AppKernel.php';

$kernel = new AppKernel('bootstrap', true);
$kernel->loadClassCache();
Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$kernel->boot();
$kernel->getContainer()->enterScope('request');
$kernel->getContainer()->set('request', $request, 'request');
$this->container = $kernel->getContainer();

顺便说一句，它可能与以下内容有关:Symfony 2.4 在 TWIG 中渲染控制器抛出渲染片段只能在处理请求时完成".例外.不过，我不想降级到 Symfony 2.3，删除 vendor 目录并没有解决我的问题.

EDIT : By the way, it might be related to that : Symfony 2.4 Rendering a controller in TWIG throws "Rendering a fragment can only be done when handling a Request." Exception . Though, I don't want to downgrade to Symfony 2.3, and deleting the vendor directory didn't fix my problem.

EDIT²:我发现问题是由于新的 RequestStack.

EDIT² : I found out that the problem is because of the new RequestStack.

在 HttpKernel 中，handleRaw(Request $request, $type = self::MASTER_REQUEST) 通常将请求推送到 RequestStack ($this->;requestStack->push($request);).因此，如果我将一个公共方法 pushRequestStack($request) 添加到 HttpKernel 中，它可以工作..但是我怎么能正确地做到这一点?我没有找到任何能够从 HttpKernel 获取 $requestStack 的公共方法(因此我可以从外部推送请求)..

In HttpKernel, handleRaw(Request $request, $type = self::MASTER_REQUEST) normally push the request to the RequestStack ($this->requestStack->push($request);). So if I add a public method pushRequestStack($request) to the HttpKernel it works.. But how could I do it properly ? I don't find any public method able to get the $requestStack from HttpKernel (so I can push the request externally)..

而且我不能使用普通"方法 ($kernel->handle($request)) 因为它会抛出一些异常，例如对于不存在的路由, 或者也适用于已经被 PHP 启动的会话..

And I can't use the "normal" method ($kernel->handle($request)) because it would throw some exceptions, for example for the route that doesn't exist, or also for the session that has already been started by PHP..

总而言之，有没有办法在不完全处理请求的情况下将我的/任何请求推送"到 requestStack 中?

推荐答案

您必须通过 Sf2 命令在request_stack"中推送新请求.

You have to push a new Request in the "request_stack" from your Sf2 command.

 $this->getContainer()->get('request_stack')->push(Request::createFromGlobals());
