Hi, the original flow was a flow from HttpRequest to HttpResponse. However the flow from cachedHostConnectionPool is
Flow[(HttpRequest, T), (Try[HttpResponse], T), ...] Here a flow accepts requests with a marker object from that request. And responses are wrapped in a try and come back together with the original marker object. Marker objects are provided to correlate responses to requests. When using connection pool responses for later requests can come before responses for earlier requests. Take a look at the documentation and code examples which should help you get up to speed with the api: https://doc.akka.io/docs/akka-http/10.0.10/scala/http/client-side/host-level.html#using-a-host-connection-pool On Tue, Nov 21, 2017 at 10:10 AM Jozsef Zsido <[email protected]> wrote: > Hi, > > I'm trying to expand the following example and replace the flow with > cachedHostConnectionPool > https://gist.github.com/rklaehn/3aa3215046df2c0a7795 > > My problem is that I'm unable to write compilable code: > > val flow = Http(system).cachedHostConnectionPool[HttpResponse]("localhost", > 56700) > > Source.single(context.request) > .map { > _.withHeaders(HttpUtils.completeHeaderList(request)) > .withUri(request.uri.path.toString()) > } > .map(r => { > println(r) > r > }) > .via(flow) > .runWith(Sink.head) > .flatMap(f => { > context.complete(f) > }) > > > What I'm doing wrong? > > Thanks, > Jozsef > > -- > >>>>>>>>>> Read the docs: http://akka.io/docs/ > >>>>>>>>>> Check the FAQ: > http://doc.akka.io/docs/akka/current/additional/faq.html > >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user > --- > You received this message because you are subscribed to the Google Groups > "Akka User List" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at https://groups.google.com/group/akka-user. > For more options, visit https://groups.google.com/d/optout. > -- >>>>>>>>>> Read the docs: http://akka.io/docs/ >>>>>>>>>> Check the FAQ: >>>>>>>>>> http://doc.akka.io/docs/akka/current/additional/faq.html >>>>>>>>>> Search the archives: https://groups.google.com/group/akka-user --- You received this message because you are subscribed to the Google Groups "Akka User List" group.
