symfony从网址中删除/ locale

Question

我需要从网址中删除/ {_ locale} 例如用户类型

127.1.1.0/en/结果必须是127.1.1.0/

127.1.1.0/en/contact结果必须是127.1.1.0/contact

我的控制器中有这样的功能

    /**
 * @Route("/", name="shop_homepage", options={"expose"=true})
 */
public function indexAction(Request $request)
{

    $locale = $request->getLocale();
     //var_dump($request->getSession()->get('_locale'));
    //throw new NotFoundHttpException('you are using unavailable langage');
    return $this->render('FrontBundle:Default:index.html.twig', 
        $this->container->get('builder.template')->init('index', $locale));
}

，我有一个侦听器，它使用会话配置我的语言环境
