Example
def ignore456(path: Path) = path match {
case s@Path.Segment(head, tail) if head.startsWith("456") =>
val newHead = head.drop(3)
if (newHead.isEmpty) tail
else s.copy(head = head.drop(3))
case _ => path
}
val ignoring456 = rewriteUnmatchedPath(ignore456)
val route =
pathPrefix("123") {
ignoring456 {
path("abc") {
complete(s"Content")
}
}
}
Get("/123/abc") ~> route ~> check {
responseAs[String] === "Content"
}
Get("/123456/abc") ~> route ~> check {
responseAs[String] === "Content"
}
