我试图实现检测用户的首选语言LocaleListener(考虑Accept-Language头),并将其存储在会议上,以避免检查它的每一个请求。 我已经开发了下面的代码来实现:
public function onKernelRequest(GetResponseEvent $event) {
$request = $event->getRequest();
if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
return;
}
$preferredLocale = $request->getPreferredLanguage($this->availableLocales);
if ($this->container->has('session')) {
$session = $this->container->get('session');
if (!$session->has('_locale')) {
$session->set('_locale', $preferredLocale);
}
} else {
$request->setLocale($preferredLocale);
}
}
该代码工作,首选语言被存储在会话,但symfony中没有考虑存储在会话翻译字符串的区域。 就我而言,我的首选语言是“pt_BR表示”当我逃离:
{{ app.request.locale }}
symfony中被转义成 'en'。 不应该被symfony的考虑存储在会话(“_区域”)来定义请求区域的价值? 这是一个正确的行为吗? 我怎样才能做到呢?
这是一个工作语言监听器。 第二种方法是将语言切换到用户偏好,其中所述用户选择。 您可以忽略此方法,如果您的用户还没有设施,以确定他们的语言。
<?php
namespace Acme\UserBundle\EventListener;
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;
}
/**

* "undefined" as configured by default in parameters.ini. If so, set as a locale the user's

*/
public function setLocaleForUnauthenticatedUser(GetResponseEvent $event)
{
if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
return;
}
$request = $event->getRequest();
if ('undefined' == $request->getLocale()) {
if ($locale = $request->getSession()->get('_locale')) {
$request->setLocale($locale);
} else {
$request->setLocale($request->getPreferredLanguage());
}
}
}
/**
* 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)
{
$user = $event->getAuthenticationToken()->getUser();
if ($lang = $user->getLanguage()) {
$this->session->set('_locale', $lang);
}
}
}
在您的services.yml:
services:
acme.language.interactive_login_listener:
class: Acme\UserBundle\EventListener\LanguageListener
calls:
- [ setSession, [@session] ]
tags:
- { name: kernel.event_listener, event: security.interactive_login, method: setLocaleForAuthenticatedUser }
acme.language.kernel_request_listener:
class: Acme\UserBundle\EventListener\LanguageListener
tags:
- { name: kernel.event_listener, event: kernel.request, method: setLocaleForUnauthenticatedUser }
哦,你有config.yml定义一个未定义的fallback_language得到它的工作。
framework:
translator: { fallback: "undefined" }
default_locale: "en"
因为symfony 2.1,该语言环境未存储在会话,但请求。 你能做些什么来解决这个问题:
