mapRejections
mapRejections
Signature
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 Transforming the Response for similar directives.
Example
// 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
}
