Silex重定向更改语言环境 [英] Silex redirect changing the locale

问题描述

我正在使用Silex 2，并且如果使用无效的语言环境加载了任何网址，我想使用默认语言环境重定向到首页.

I am using Silex 2 and I would like to redirect to homepage with default locale if any url is loaded using an invalid locale.

    // homepage / root
    $this->get('{_locale}/', function (Request $request) use ($app) {
        return $app['twig']->render('index/index.html.twig', array());
    })->bind('homepage');

在中间件之前:

    // i18n Control
    $locale = $request->getLocale();
    $allowLocale = ['en','es','de'];
    if (!in_array($locale, $allowLocale)) {
        $request->setLocale('en');
        $response = new \Symfony\Component\HttpFoundation\RedirectResponse($app['url_generator']->generate('homepage'), 301);
        $response->prepare($request);
        return $response->send();
    }

但是这段代码会产生无限循环.

But this code produces an infinite loop.

我想要:

如果用户插入以下URL:/es/foo，那么一切正常.

If user insert this URL: /es/foo then all is ok.

如果用户输入以下URL:/fr/foo，则必须将其重定向到/en.

If user insert this URL: /fr/foo then he must be redirect to /en.

谢谢.

推荐答案

您可以执行相同的操作，但是很容易，因为可以将URL参数传递给url_generator服务.另外，为使您的应用更灵活，更不易出错，您还应该为全局配置( allowedLocales 和 defaultLanguage )使用容器:

You can do the same, but easily as you can pass the URL parameter to the url_generator service. Also to make your app more flexible and less error prone, you should embarace the container for global configurations (for allowedLocales and defaultLanguage):

// somewhere in your configuration
$app['defaultLanguage'] = 'en';
$app['allowedLocales'] = ['en','es','de']

// Then in your controller
$locale = $request->getLocale();
if (!in_array($locale, $app['allowLocales'])) {

    $request->setLocale($app['defaultLanguage']);
    $app['translator']->setLocale($app['defaultLanguage']);

    return $app->redirect(
        $app['url_generator']->generate('homepage', ["locale" => $app['defaultLanguage']]), 
        301
    );
}
