mapInnerRoute
§Signature
§Description
Changes the execution model of the inner route by wrapping it with arbitrary logic.
The mapInnerRoute directive is used as a building block for Custom Directives to replace the inner route
with any other route. Usually, the returned route wraps the original one with custom execution logic.
§Example
- val completeWithInnerException =
- mapInnerRoute { route => ctx =>
- try {
- route(ctx)
- } catch {
- case NonFatal(e) => ctx.complete(s"Got ${e.getClass.getSimpleName} '${e.getMessage}'")
- }
- }
-
- val route =
- completeWithInnerException {
- complete(throw new IllegalArgumentException("BLIP! BLOP! Everything broke"))
- }
-
- // tests:
- Get("/") ~> route ~> check {
- responseAs[String] shouldEqual "Got IllegalArgumentException 'BLIP! BLOP! Everything broke'"
- }
