我正在尝试使用 Symfony 从数据库中的“区域设置”字段更改用户区域设置。我阅读了 Symfony 手册（例如如何粘贴会话），但在我的应用程序中没有任何作用。翻译器仍然获得默认语言环境...

我创建了侦听器、订阅者...以动态更改语言环境，但是由于它们是在防火墙侦听器之前加载的，因此我无法更改当前值。

我试图更改优先订阅者，但我丢失了用户实体。我试图在控制器中设置语言环境请求，但我认为为时已晚。

我不想在 URL 中添加语言环境。

这是我的订阅者 - 听众 - 代码：

public function onKernelRequest(RequestEvent $event)
{
   $user = $this->tokenStorage->getToken()->getUser();
   $request = $event->getRequest();
   $request->setLocale($user->getLocale());
}

在订阅者中，我添加了：

public static function getSubscribedEvents()
{
   return [
     KernelEvents::REQUEST => [['onKernelRequest', 0]],
   ];
}

在这里，我的完整代码：

框架.yml：

default_locale: fr

服务.yml：

parameters:
    locale: 'fr'
    app_locales: fr|en|

翻译.yml：

framework:
    default_locale: '%locale%'
    translator:
        paths:
            - '%kernel.project_dir%/translations'
        fallbacks:
            - '%locale%'

LocaleSubscriber.php：

namespace App\EventSubscriber;

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

class LocaleSubscriber implements EventSubscriberInterface
{
    private $defaultLocale;

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

    public function onKernelRequest(RequestEvent $event)
    {
        $request = $event->getRequest();
        if (!$request->hasPreviousSession()) {
            return;
        }
        // try to see if the locale has been set as a _locale routing parameter
        if ($locale = $request->attributes->get('_locale')) {
            $request->getSession()->set('_locale', $locale);
        } else {
            // if no explicit locale has been set on this request, use one from the session
            $request->setLocale($request->getSession()->get('_locale', $this->defaultLocale));
        }
    }

    public static function getSubscribedEvents()
    {
        return [
            // must be registered before (i.e. with a higher priority than) the default Locale listener
            KernelEvents::REQUEST => [['onKernelRequest', 20]],
        ];
    }
}

UserLocaleSubscriber.php

// src/EventSubscriber/UserLocaleSubscriber.php
namespace App\EventSubscriber;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\Session\SessionInterface;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
use Symfony\Component\Security\Http\SecurityEvents;

/**
 * Stores the locale of the user in the session after the
 * login. This can be used by the LocaleSubscriber afterwards.
 */
class UserLocaleSubscriber implements EventSubscriberInterface
{
    private $session;

    public function __construct(SessionInterface $session)
    {
        $this->session = $session;
    }

    public function onInteractiveLogin(InteractiveLoginEvent $event)
    {
        $user = $event->getAuthenticationToken()->getUser();

        if (null !== $user->getLocale()) {
            $this->session->set('_locale', $user->getLocale());
        }
    }

    public static function getSubscribedEvents()
    {
        return [
            SecurityEvents::INTERACTIVE_LOGIN => 'onInteractiveLogin',
        ];
    }
}

前控制器注释：

/**
     * @Route("/user/locale", name="user_locale", requirements={"_locale" = "%app.locales%"})
     * @Route("/{_locale}/user/locale", name="user_locale_locale", requirements={"_locale" = "%app.locales%"})
     */

  1. 使用 查找防火墙侦听器的优先级debug:event kernel.request。
  2. 确保您UserLocaleSubscriber在防火墙侦听器之后立即执行。
  3. 自动装配TranslatorInterface并手动设置翻译器区域设置。
// src/EventSubscriber/UserLocaleSubscriber.php
namespace App\EventSubscriber;

use Symfony\Component\EventDispatcher\EventSubscriberInterface;
use Symfony\Component\HttpFoundation\Session\SessionInterface;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;
use Symfony\Component\Security\Http\SecurityEvents;
use Symfony\Contracts\Translation\TranslatorInterface;

/**
 * Stores the locale of the user in the session after the
 * login. This can be used by the LocaleSubscriber afterwards.
 */
class UserLocaleSubscriber implements EventSubscriberInterface
{
    private $session;

    private $translator;

    public function __construct(SessionInterface $session, TranslatorInterface $translator)
    {
        $this->session = $session;
        $this->translator = $translator;
    }

    public function onInteractiveLogin(InteractiveLoginEvent $event)
    {
        $user = $event->getAuthenticationToken()->getUser();

        if (null !== $user->getLocale()) {
            $this->translator->setLocale($user->getLocale());
        }
    }

    public static function getSubscribedEvents()
    {
        return [
            SecurityEvents::INTERACTIVE_LOGIN => ['onInteractiveLogin', 7]
        ];
    }
}

如果没有看到您正在使用的完整代码，很难提供帮助。

Symfony 也有它自己的 LocaleListener。确保首先执行您的。

    /**
     * @return array
     */
    public static function getSubscribedEvents()
    {
        return [
            // must be registered before (i.e. with a higher priority than) the default Locale listener
            KernelEvents::REQUEST => [['onKernelRequest', 20]],
        ];
    }
