akka - Websocket with async handler -


i can't akka http websockets work connection.handlewithasynchandler. here code in scala (i'm using latest version of akka http)

import akka.actor.actorsystem import akka.http.scaladsl.http import akka.http.scaladsl.model.httpmethods._ import akka.http.scaladsl.model._ import akka.http.scaladsl.model.ws.{message, upgradetowebsocket} import akka.stream.actormaterializer import akka.stream.scaladsl.{flow, sink}  import scala.concurrent.future  object server extends app {     implicit val system = actorsystem("server-system")     implicit val materializer = actormaterializer()     implicit val dispatcher = system.dispatcher     implicit val formats = net.liftweb.json.defaultformats      val serversource = http().bind(interface = "localhost", port = 9000)      val requesthandler: httprequest => future[httpresponse] = {         case request @ httprequest(get, uri.path("/websocket"), _, _, _) => {             future {                 request.header[upgradetowebsocket] match {                     case some(upgrade) => {                         upgrade.handlemessages(flow[message])                     }                     case none => {                         httpresponse(statuscodes.badrequest)                     }                 }             }         }         case _: httprequest => {             future.successful(httpresponse(statuscodes.badrequest))         }     }      val bindingfuture = serversource.to(sink.foreach { connection =>         connection.handlewithasynchandler(requesthandler)     }).run() }

and js code test it:

<!doctype html> <html lang="en"> <head>     <meta charset="utf-8">     <title>document</title> </head> <body> <script>     var ws = new websocket('ws://localhost:9000/websocket');      ws.onopen = function() {         console.log('open');          ws.send('test message');     };      ws.onmessage = function(msg) {         console.log(msg.data);     };      ws.onclose = function() {         console.log('close');     }; </script> </body> </html>

in console get

open close

why websocket connection closed directly after being opened ?

updating akka 2.4.2-rc2 did trick.
