Silex 2：在路由中声明{_locale}可选

Question

I would like routing these kind of URLs:

/hello/{name}
/en/hello/{name}
/es/hello/{name}

I have created this Controller class:

<?php

namespace Fw\Controllers;

use Silex\Application;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Fw\Application as FwApplication;

class Hello implements ControllerProviderInterface {

    const URL_BASE = '/hello';
    const URL_BASE_LOCALE = '/{_locale}/hello';

    public function connect(Application $app) {
        $controllers = $app['controllers_factory'];

        $controllers
                ->get('/{name}/', array($this, 'nameAction'))
                ->bind('hello_name')
        ;

        return $controllers;
    }

    public function nameAction(FwApplication\ApplicationBase $app, Request $request, $name) {
        return new Response('Hello ' . $name, 200);
    }
}

And it has been registered in this way:

$app->mount(FwControllers\Hello::URL_BASE_LOCALE, new FwControllers\Hello());
$app->mount(FwControllers\Hello::URL_BASE, new FwControllers\Hello());

This URL works good: /hello/foo But this one not: /en/hello/foo, this error is shown:

NotFoundHttpException in RouterListener.php line 125: No route found for "GET /en/hello/foo/"

It seems that the second "mount" sentence is overwritten to first one.

Can anybody help me with this problem? How can I set routing with optional {_locale}?

Thanks.

I had same problem and wrote service provider that automatically adds locale to all routes https://github.com/pmaxs/silex-locale. May be it will satisfy your requirements.
