mapRejections
Description
Low level directive – unless you’re sure you need to be working on this low-level you might instead want to try the handleRejections directive which provides a nicer DSL for building rejection handlers.
The mapRejections
directive is used as a building block for Custom Directives to transform a list of rejections from the inner route to a new list of rejections.
See Response Transforming Directives for similar directives.
Example
- Scala
-
source
// ignore any rejections and replace them by AuthorizationFailedRejection val replaceByAuthorizationFailed = mapRejections(_ => List(AuthorizationFailedRejection)) val route = replaceByAuthorizationFailed { path("abc")(complete("abc")) } // tests: Get("/") ~> route ~> check { rejection shouldEqual AuthorizationFailedRejection } Get("/abc") ~> route ~> check { status shouldEqual StatusCodes.OK }
