无法覆盖Symfony 2请求中的pathInfo [英] Unable to overwrite pathInfo in a Symfony 2 Request

问题描述

我正在尝试处理别名（友好网址），可能我做的不正确。我想做的就是将 / blog / my-post-about-something之类的网址转换为 / posts / 23。

I'm trying to deal with aliases (friendly-urls) and probably I'm not doing it right. What I want to do is to transform urls like '/blog/my-post-about-something' into '/posts/23'.

我写了一个侦听器对于进行一些操作并修改原始请求的kernel.request事件

I have written a listener for the kernel.request event that makes some operations and modifies the original request

class RequestListener
{

    public function onKernelRequest(KernelEvent $event)
    {
        $request = $event->getRequest();
        $converted_path = $this->getPathIfAny($request);
        if ($converted_path) {
            $request->server->set('REQUEST_URI', $converted_path);
        }
    }

    public function getPathIfAny(Request $request)
    {
        return $somePathOrNull;
    }
}

所有逻辑均正常运行并更新原始请求。问题是，即使我更改了 REQUEST_URI，属性$ pathInfo仍然保持不变并指向先前的路径，因此我不断收到404错误。

All the logic works properly and updates the original request. The problem is, even if I change the 'REQUEST_URI', the property $pathInfo remains unaltered and pointing to the previous path, so I keep getting 404 errors.

有什么方法可以完全覆盖uri，还是应该尝试以其他方式解决问题？

Is there any way to override the uri completely, or should I try to solve the problem in a different manner?

这里是侦听器的定义

my_cmf.request_listener:
    class: My\CMFBundle\Event\RequestListener
    tags:
      - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest , priority: -10}

推荐答案

我的项目有类似的问题。我能够更新路径信息，但仍然很难将其传递给后续事件

I have a similar issue with my project. I was able to update the path info, but still struggling to get it passed to subsequent events

尝试一下：

$event->getRequest()->server->set('REQUEST_URI', '/en/guestbook');
$event->getRequest()->initialize($event->getRequest()->query->all(), $event->getRequest()->request->all(), $event->getRequest()->attributes->all(), $event->getRequest()->cookies->all(), $event->getRequest()->files->all(), $event->getRequest()->server->all(), $event->getRequest()->getContent());

var_dump($event->getRequest()->getPathInfo());

initialize方法将重置整个类。

The initialize method resets the whole class.
