Symfony无法将区域设置为未定义

Question

我正在尝试在Symfony 2.7项目中使用locale。我想将区域设置设置为$请求-

我读过不同的帖子，比如：https://gist.github.com/Dattaya/1670163/450a8054d84b30c16174a75eb60f139e2602cdea但是我在setLocaleForRunAuthenticatedUser（）中遇到了一个问题，因为我无法将区域设置设置为undefined。

这是我的config.yml文件：

parameters:
locale: "undefined"
session:
    storage:
        options:
            name: app_sess
framework:
    translator:      { fallback: "undefined" }
    default_locale:  "%locale%"
    secret:          "%secret%"

我定义了服务：

acme.locale.interactive_login_listener:
    class: acme\GeneralBundle\EventListener\LocaleListener
    calls:
        - [ setSession, [@session] ]
    tags:
        - { name: kernel.event_listener, event: security.interactive_login, method: setLocaleForAuthenticatedUser }

acme.locale.kernel_request_listener:
    class: acme\GeneralBundle\EventListener\LocaleListener
    tags:
        - { name: kernel.event_listener, event: kernel.request, method: setLocaleForUnauthenticatedUser, priority: 17 }

下面是方法：

public function setLocaleForUnauthenticatedUser(GetResponseEvent $event)
{
    if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
        return;
    }

    $request = $event->getRequest();
    file_put_contents('test.txt', $request->getLocale(), FILE_APPEND);
    if ($request->getLocale() === 'undefined' ) {
        $request->setLocale($request->getPreferredLanguage());
    }
}

在此代码$请求-

最后我找到了一个解决方案：config.ymlfile

parameters:
    locale: "undefined"

framework:
    translator:      { fallback: "en" }
    default_locale:  "%locale%"

服务。yml文件

acme.locale.interactive_login_listener:
    class: acme\GeneralBundle\EventListener\LocaleListener
    calls:
        - [ setSession, [@session] ]
    tags:
        - { name: kernel.event_listener, event: security.interactive_login, method: setLocaleForAuthenticatedUser }

acme.locale.kernel_request_listener:
    class: acme\GeneralBundle\EventListener\LocaleListener
    tags:
        - { name: kernel.event_listener, event: kernel.request, method: setLocaleForUnauthenticatedUser, priority: 10 }

LocaleListener文件

class LocaleListener {

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


public function setLocaleForUnauthenticatedUser(GetResponseEvent $event)
{
    if (HttpKernelInterface::MASTER_REQUEST !== $event->getRequestType()) {
        return;
    }

    $request = $event->getRequest();
    $sessionLocale = $request->getSession()->get('_locale');
    if ($sessionLocale == '') {
        $request->setLocale(substr($request->getPreferredLanguage(), 0, 2));
    } else {
        $request->setLocale(substr($sessionLocale, 0, 2));
    }
}


public
function setLocaleForAuthenticatedUser(InteractiveLoginEvent $event)
{
    $user = $event->getAuthenticationToken()->getUser();
    $preferences = $user->getPreferences();

    if ($preferences !== null && gettype($preferences) === 'array' && isset($preferences['language'])) {
        $event->getRequest()->setLocale(substr($preferences['language'], 0, 2));
        $this->session->set('_locale', substr($preferences['language'], 0, 2));
    }
}

}

此解决方案的目的是检查$request-
