如何在Symfony2路由中具有可选参数？(How can i have optional parameters in Symfony2 route)

我有以下代码：

/** * Lists all User entities. * * @Route("/{cid}",defaults={"cid" = null},name="user") * @Template() */ public function indexAction($cid=null) {}

现在，如果我键入site/user/1那么它可以工作，但如果我键入site/user/它说：

No route found

我怎么能这样做呢？

I have this code below :

/** * Lists all User entities. * * @Route("/{cid}",defaults={"cid" = null},name="user") * @Template() */ public function indexAction($cid=null) {}

Now if I type site/user/1 then it works, but if I type site/user/ it says:

No route found

How can I have it that both routes work?

最满意答案

尝试去site/user （请注意，末尾没有反斜杠）。

一般它应该工作，我有相似的配置工作。

但是如果所有其他方式都失败，您可以随时为同一动作定义多个路由，即

/** * Lists all User entities. * * @Route("/", name="user_no_cid") * @Route("/{cid}", name="user") * @Template() */ public function indexAction($cid=null) {

Try to go to site/user (notice no backslash at the end).

Generally it should work, I have relatively similar configuration working.

But if all else fails you can always define multiple routes for same action, i.e.

/** * Lists all User entities. * * @Route("/", name="user_no_cid") * @Route("/{cid}", name="user") * @Template() */ public function indexAction($cid=null) {
