pathEndOrSingleSlash

Signature

Description

Only passes the request to its inner route if the unmatched path of the RequestContext is either empty or contains only one single slash.

This directive is a simple alias for rawPathPrefix(Slash.? ~ PathEnd) and is mostly used on an inner-level to discriminate "path already fully matched" from other alternatives (see the example below).

It is equivalent to pathEnd | pathSingleSlash but slightly more efficient.

Example

val route =
  pathPrefix("foo") {
    pathEndOrSingleSlash {
      complete("/foo")
    } ~
      path("bar") {
        complete("/foo/bar")
      }
  }

// tests:
Get("/foo") ~> route ~> check {
  responseAs[String] shouldEqual "/foo"
}

Get("/foo/") ~> route ~> check {
  responseAs[String] shouldEqual "/foo"
}

Get("/foo/bar") ~> route ~> check {
  responseAs[String] shouldEqual "/foo/bar"
}
