使用*path段执行某项操作-即使不执行任何操作...

Do something with *path segment - even if nothing...

路线:

OPTIONS    /          controllers.Application.options(path: String ?= "")
OPTIONS    /*path     controllers.Application.options(path)

操作:

def options(path: String) = Action {
  Ok("").withHeaders(
    "Access-Control-Allow-Origin" -> "*",
    "Access-Control-Allow-Methods" -> "GET, POST, PUT, DELETE, OPTIONS",
    "Access-Control-Allow-Headers" -> "Accept, Origin, Content-type, X-Json, X-Prototype-Version, X-Requested-With",
    "Access-Control-Allow-Credentials" -> "true",
    "Access-Control-Max-Age" -> (60 * 60 * 24).toString
  )
}
