使用可选参数配置Silex路由

Question

我已经配置了这两条路线

$app->match ( '/controller/param/{country}/{q}', "demo.controller:demoAction" )->value ( 'country', 'de' )->value('q', '')->bind ( 'demo_action_with_country' );
$app->match ( '/controller/param/{q}', "demo.controller:demoAction" )->value ( 'q', '' )->bind ( 'demo_action_without_country' );

但是--这是行不通的。如果我调用/controller/param/Test-String，则路由匹配并返回内容。如果我打电话给/controller/param/DE/Test-String，我就能得到NotFoundHttpException

我怎样才能解决这个问题？

好吧，我可以自己解决。这是我的解决方案：

$app->match ( '/controller/param/{q}', "demo.controller:demoAction" )->value ( 'q', false )->bind ( 'demo_action_without_country' );
$app->match ( '/controller/param/{country}/{q}', "demo.controller:demoAction" )->value ( 'country', false )->value('q', '')->bind ( 'demo_action_with_country' );
