pathSingleSlash
Description
Only passes the request to its inner route if the unmatched path of the RequestContextRequestContext contains exactly one single slash.
This directive is a simple alias for pathPrefix(PathEnd)
and is mostly used for matching requests to the root URI (/
) on an inner-level to discriminate “all path segments matched” from other alternatives (see the example below). For a comparison between path directives check Overview of path directives.
Example
- Scala
-
val route = pathSingleSlash { complete("root") } ~ pathPrefix("ball") { pathSingleSlash { complete("/ball/") } ~ path(IntNumber) { int => complete(if (int % 2 == 0) "even ball" else "odd ball") } } // tests: Get("/") ~> route ~> check { responseAs[String] shouldEqual "root" } Get("/ball") ~> route ~> check { handled shouldEqual false } Get("/ball/") ~> route ~> check { responseAs[String] shouldEqual "/ball/" } Get("/ball/1337") ~> route ~> check { responseAs[String] shouldEqual "odd ball" }
- Java
-
final Route route = route( pathSingleSlash(() -> complete("root")), pathPrefix("ball", () -> route( pathSingleSlash(() -> complete("/ball/")), path(integerSegment(), (i) -> complete((i % 2 == 0) ? "even ball" : "odd ball")) ) ) ); // tests: testRoute(route).run(HttpRequest.GET("/")).assertEntity("root"); testRoute(route).run(HttpRequest.GET("/ball")).assertStatusCode(StatusCodes.NOT_FOUND); testRoute(route).run(HttpRequest.GET("/ball/")).assertEntity("/ball/"); testRoute(route).run(HttpRequest.GET("/ball/1337")).assertEntity("odd ball");
