Hello,
I've got this code:
def httpGet( uri:String )(implicit s:ActorSystem) = {
implicit val materializer = FlowMaterializer()
var r:HttpResponse = null
val req = HttpRequest(HttpMethods.GET, Uri(uri))
val host:String = req.uri.authority.host.toString
val port:Int = req.uri.effectivePort
val httpClient = Http().outgoingConnection(host,port).flow
val consumer = Sink.foreach[HttpResponse] { resp ⇒ r = resp }
*val finishFuture = Source.single(req).via(httpClient).runWith(consumer)* *//
<-- GOES BOOM HERE*
Await.result(finishFuture, Duration("3 seconds"))
// unpack result
(r.status.intValue,
Await.result(r.entity.toStrict(FiniteDuration(3,"seconds")), Duration("3
seconds") )
.data
.utf8String)
}
This works pretty well--for a while. When run in a long-running process,
eventually it dies with the exception below.
Any idea what's cause it?
Thanks for any ideas,
Greg
