[akka-http] Can I get the last rejection and request context at the same time?

[yar....@gmail.com]

Hi, hakkers!

I have a route like the following,

post {
  entity(as[Profile]) { profile =>
    ...
  }
}

and if entity is malformed or absent altogether, I want to give back a BadRequest with a useful body containing request details (which I need a request context for) and error messages from Unmarshaller (which I can get from rejection). Is it possible to get the last rejection and RequestContext at the same time?

It turns out it is, I wish examples in documentation depicted that:

val routeRejectionHandler = RejectionHandler.newBuilder().handle{ 
  case MalformedRequestContentRejection(msg, _) ⇒ ctx ⇒ {
    val method = ctx.request.method
    val uri = ctx.request.getUri()
    val entity = Await.result(ctx.request.entity.toStrict(1.second), 1.second).data.decodeString("UTF-8")
    val msg = s"Malformed request body $entity in request $method $uri"
    ctx.log.error(msg)
    ctx.complete(BadRequest -> s"Could not deserialize request body")
  }
}.result
