Nice, thanks! More examples, explanations and learning materials are very
welcome for akka-http, to make it more approachable.
Btw, some simplification of usage for http-client would help, too.
Internally we came up with something like:
trait HttpClient {
implicit def system: ActorSystem
implicit def materializer: ActorMaterializer
def connectionContext: HttpsConnectionContext
protected val http = Http()
//execs only if result was successful
def exec[T, U](r: HttpRequest, f: U => T)(implicit u: Unmarshaller[
HttpResponse, U], ec: ExecutionContext): Future[T] =
http.singleRequest(r).flatMap(u.apply(_).map(f))
//execs only if result was successful
def execOK[T, U](r: HttpRequest, f: U => T)(implicit u: Unmarshaller[
HttpResponse, U], ec: ExecutionContext): Future[T] =
http.singleRequest(r).flatMap { rsp =>
if (rsp.status.isSuccess()) u.apply(rsp).map(f)
else Unmarshal(rsp.entity).to[String].flatMap(str => Future.failed[T](
SgHttpError(rsp.status.intValue(), str)))
}
}
