传递路线中的参数值？

Question

在我的控制器中,我有一个删除方法:

delete(String id, boolean confirmed)

现在在路由中我想相应地映射两个URI:

GET /item/:id/delete           controllers.Application.delete(id:String, false)
GET /item/:id/delete/confirmed controllers.Application.delete(id:String, true)

(有趣的部分是根据URI传递给delete方法的第二个参数)

但是这给了我以下错误:

 identifier expected but 'false' found. 

我究竟做错了什么？

正确的语法是:

GET /item/:id/delete           controllers.Application.delete(id:String, confirmed:Boolean ?= false)
GET /item/:id/delete/confirmed controllers.Application.delete(id:String, confirmed:Boolean ?= true)
