Changes the response that was generated by the inner route.


def mapHttpResponse(f: HttpResponse  HttpResponse): Directive0 


The mapHttpResponse directive is used as a building block for Custom Directives to transform a response that was generated by the inner route. This directive transforms only complete responses. Use mapHttpResponsePart, instead, to transform parts of chunked responses as well.

See Directives transforming the response for similar directives.


def overwriteResultStatus(response: HttpResponse): HttpResponse =
  response.copy(status = StatusCodes.BadGateway)
val route = mapHttpResponse(overwriteResultStatus)(complete("abc"))

Get("/abcdef?ghi=12") ~> route ~> check {
  status === StatusCodes.BadGateway
