Question

我使用Symfony 2.6.0 我需要设置用户的语言而不是默认语言。更改区域设置的服务：

 helper.interactive_login_listener:
        class: HelperBundle\Listeners\LanguageListener
        calls:
            - [ setSession, [@session] ]
        tags:
            - { name: kernel.event_listener, event: security.interactive_login, method: setLocaleForAuthenticatedUser }

 helper.language.kernel_request_listener:
        class: HelperBundle\Listeners\LanguageListener
        tags:
            - { name: kernel.event_listener, event: kernel.request, method: setLocaleForUnauthenticatedUser }

代码：

namespace HelperBundle\Listeners;

use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\HttpKernelInterface;

class LanguageListener
{
    private $session;

    public function setSession(Session $session)
    {
        $this->session = $session;
    }

    /**
     * kernel.request event. If a guest user doesn't have an opened session, locale is equal to
     * "undefined" as configured by default in parameters.ini. If so, set as a locale the user's
     * preferred language.
     *
     * @param \Symfony\Component\HttpKernel\Event\GetResponseEvent $event
     */
    public function setLocaleForUnauthenticatedUser(GetResponseEvent $event)
    {

        if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
            return;
        }
        $request = $event->getRequest();
        $request->setLocale('ru');

    }

    /**
     * security.interactive_login event. If a user chose a language in preferences, it would be set,
     * if not, a locale that was set by setLocaleForUnauthenticatedUser remains.
     *
     * @param \Symfony\Component\Security\Http\Event\InteractiveLoginEvent $event
     */
    public function setLocaleForAuthenticatedUser(InteractiveLoginEvent $event)
    {

        $this->session->set('_locale', 'ru');

    }
}

配置：

framework:
    translator:      ~
    default_locale:  ~

在控制器中：

namespace HelperBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

abstract class PrototypeController extends Controller
{
    protected $model;
    protected $flashBag;

    //Метод загрузки модели контроллера
    abstract function loadServiceModelEvent($model_service_name);

    //Вывод шаблона
    protected function renderPage($template, $response)
    {
        print $this->get('request')->getLocale().'==';
        print $this->get('request')->getSession()->get('_locale'); die();

结果打印：

ru==ru

同时使用英语（en）。但是，如果设置

framework:

translator:      ~
default_locale:  ru

然后一切都很好。如何改变语言？谢谢！

如果我正确理解了这个问题，问题是听众没有正确设置语言。在这种情况下，侦听器的问题是，您无法为其执行设置优先级。那是EventSubscriber来参加聚会的时候。

# app/config/services.yml
services:
    app.exception_subscriber:
        class: AppBundle\EventSubscriber\LanguageListener
        tags:
            - { name: kernel.event_subscriber }

在这种情况下你的听众会这样：

class LanguageListener implements EventSubscriberInterface
{
    private $session;

    public function setSession(Session $session)
    {
        $this->session = $session;
    }

    /**
     * @return array
     */
    public static function getSubscribedEvents()
    {
        return [
            KernelEvents::REQUEST => [
                ['onKernelRequest', 9],
            ],
        ];
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
    ...
    }
}

正如您所看到的差异并不大，但在getSubscribedEvents函数中，您可以指定将使用的优先级（在本例中为9）。您可以在official documentation中了解有关优先级的更多信息。

您需要确保在Symfony框架初始化LocaleListener之前执行订阅者。该侦听器（实际上是订阅者）使用设置“搞乱”并设置默认值，如果有的话。因此，如果您之前拦截了语言环境，它应该可以正常工作。

您可以通过CLI命令检查所有已注册的侦听器和订阅者：

php bin/console debug:event-dispatcher
