Symfony：粘性语言环境不起作用

Question

我正在尝试按照 Symfony 教程中的“在用户会话期间使区域设置“粘滞””，但是我遇到了一个错误，我不知道为什么...

当我单击一个标志来更改语言时，新语言会在会话中设置，并且在重定向之后，我在“$request->getLocale()”中获得了所选语言但不在翻译器...你知道这个问题吗？非常感谢！

编辑：我只想按会话使用语言环境

LocaleListener.php

<?php
// src/AppBundle/EventListener/LocaleListener.php
namespace AppBundle\EventListener;

use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\KernelEvents;
use Symfony\Component\EventDispatcher\EventSubscriberInterface;

class LocaleListener implements EventSubscriberInterface
{
    private $defaultLocale;

    public function __construct($defaultLocale = 'fr')
    {
        $this->defaultLocale = $defaultLocale;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $request = $event->getRequest();
        if (!$request->hasPreviousSession()) {
            return;
        }

        if ($locale = $request->attributes->get('_locale')) {
            $request->getSession()->set('_locale', $locale);
        } else {
            // Si aucune locale n'a été fixée explicitement dans la requête, on utilise celle de la session
            $request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
        }
    }

    public static function getSubscribedEvents()
    {
        return array(
            // must be registered after the default Locale listener
            KernelEvents::REQUEST => array(array('onKernelRequest', 17)),
        );
    }
}

change_language.html.twig（更改语言）

<a href="{{ path('app_change_language', {'language': key}) }}" >key</a>

语言控制器.php

<?php

namespace AppBundle\Controller;

use AppBundle\Form\Model\Language\Language;
use AppBundle\Form\Type\LanguageType;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request;

/**
 * Class LanguageController.
 */
class LanguageController extends AbstractController
{
    /**
     * @Route("/changelanguage/{language}", name="app_change_language", options={"expose"=true})
     *
     * @param Request $request
     *
     * @return \Symfony\Component\HttpFoundation\Response
     */
    public function setLanguageAction(Request $request, $language = null)
    {

        $defaultLanguage = $request->getLocale();

        // pour test
        $languages = [
            'fr' => 'French',
            'gb' => 'English',
            'es' => 'Spanish',

        ];

        if(isset($language))
        {


            $this->get('session')->set("_locale", $language);

            $url = $this->generateUrl('app_homepage');
            return $this->redirect($url);

        }

        return $this->render('AppBundle:Language:change_language.html.twig',  array(
                   'languages' => $languages,
                   'defaultLanguage' => $defaultLanguage)
                );
    }
}

app/config/services.xml

  app.eventListeners.locale_listener:

      arguments: ["%kernel.default_locale%"]

按照 Fracsi 的回答：

默认控制器：

<?php 

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Cookie;

    /**
     * Class DefaultController.
     */
    class DefaultController extends AbstractController
    {

        /**
         * @Route("/", name="app_homepage")
         *
         * @param Request $request
         *
         * @return \Symfony\Component\HttpFoundation\Response
         */
        public function indexAction(Request $request)
        {
            $locale     = $request->getLocale();
            // locale = "gb" (after click on the flag and redirect)

            $translator = $this->get('translator');

            var_dump($translator->getLocale()); // fr

            $this->get('translator')->setLocale('gb');

            var_dump($this->get('translator')->getLocale()); // display "gb"
            var_dump($translator->trans('menu.home')); // display translation in french...

        }

Answer 2

答案在这里：

最后，我找到了原因……翻译器获得了良好的语言环境，但每次都被外部捆绑包（lexik 翻译）替换……现在它可以工作了！
