akka-http send continuous chunked http response (stream)

Question

I have this crude test example with akka-http client and server.

Server.scala:

import akka.actor.ActorSystem
import akka.stream.ActorMat         


        

Answer 1

Found the answer.

Server.scala:

import akka.actor.ActorSystem
import akka.stream.ActorMaterializer
import akka.stream.scaladsl.{Source, Sink}
import akka.http.scaladsl.Http
import akka.http.scaladsl.model.HttpMethods._
import akka.http.scaladsl.model._
import scala.concurrent.Future
import scala.concurrent.duration._

class Server extends Runnable {

    def run() = {

        implicit val system = ActorSystem("server")
        implicit val materializer = ActorMaterializer()

        val serverSource = Http().bind(interface = "localhost", port = 8200)

        val requestHandler: HttpRequest => HttpResponse = {
            case HttpRequest(GET, Uri.Path("/stream"), _, _, _) =>
                HttpResponse(entity = HttpEntity.Chunked(ContentTypes.`text/plain`, Source(0 seconds, 1 seconds, "test")))
        }

        val bindingFuture: Future[Http.ServerBinding] = serverSource.to(Sink.foreach { connection =>
            connection handleWithSyncHandler requestHandler
        }).run()

    }

}
