mapHttpResponse

Changes the response that was generated by the inner route.

Signature

def mapHttpResponse(f: HttpResponse ⇒ HttpResponse): Directive0 

Description

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.

Example

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
}
