Hi,
I am trying to connect http client to a http service exposed by server, the
source should send request every 1 second for that I have crated following
partial graphs:
def httpSourceGraph() = {
Source.fromGraph(GraphDSL.create() { implicit builder =>
val sourceOutLet = builder.add(Source.tick(FiniteDuration(0,
TimeUnit.SECONDS), FiniteDuration(1,
TimeUnit.SECONDS),
HttpRequest(uri ="/test", method = HttpMethods.GET))).out
// expose outlet
SourceShape(sourceOutLet)
})
}
def httpConnFlow() = {
Flow.fromGraph(GraphDSL.create() { implicit builder =>
val httpSourceFlow = builder.add(Http(system).outgoingConnection(host =
"localhost", port = 8080))
FlowShape(httpSourceFlow.in, httpSourceFlow.out)
})
}
the graph is composed as
val response= httpSourceGraph1.via(httpConnFlow()).runForeach(println)
if the http server (localhost:8080/test) is up and running, everything works
fine, every 1 second I can see the response coming back from the server. I am
not able to any response in case of either server is down or it goes down
later.
*I think it should give me following error:*
akka.stream.StreamTcpException: Tcp command
[Connect(localhost/127.0.0.1:8080,None,List(),Some(10 seconds),true)] failed
Thanks for the help.
