Symfony强制路由默认参数始终显示在url中

I'm currently facing an issue I have no idea how to solve. For a route, I can have the following annotation :

@Route("/foo/{choice}", name="foo_route", defaults={"choice" = "bar"})

This route can be reached by :

  • /foo/helloworld
  • /foo/bar
  • /foo

The last case is rather problematic. I would like the choice to be always visible in the url, even if it is the default choice. Is such a thing possible ?

我目前正面临一个问题,我不知道如何解决。 对于一条路线,我可以拥有 以下注释:

  @Route(“/ foo / {choice}”,name =“foo_route”,defaults = {“choice”=“bar”})
 <  / code>  
 
 

可通过以下方式联系到此路线:

  • / foo / helloworld
  • / foo / bar
  • / foo

    最后一种情况相当棘手。 我希望选择始终在URL中可见,即使它是默认选择。 这样的事情可能吗?

    One way to do this would be something like this:

    /**
     * @Route("/foo/{choice}", name="foo_route")
     */
    function fooAction($choice = NULL) {
        if ($choice === NULL) {
            return $this->redirectToRoute('foo_route', ['choice' => 'bar']);
        }
    }
    

    That is, remove the defaults, allow $choice === NULL, and force the redirect to your "default" value.

    Alternatively, you could embed JavaScript logic in the page to use history manipulation to modify the url. This would allow you to avoid forcing a redirect. However, forcing the redirect is probably easier, and keeps the logic for handling this entirely in the PHP.
