Hello,
I'm very excited about the new Akka streams + http features. Migrating
some sample code from Spray to Akka-Http I encountered a small problem in a
utility class I use to fire http requests. Code here:
import akka.http.Http
import akka.http.model._
import akka.io.IO
import akka.pattern.ask
import akka.actor.ActorSystem
import akka.util.Timeout
import scala.concurrent.{ Await, Future }
import scala.concurrent.duration._
import scala.language.postfixOps
import scala.concurrent.ExecutionContext.Implicits.global
object Util {
def httpGet( uri:String )(implicit s:ActorSystem, timeout:Timeout = 30
seconds) = {
val resp = _http( HttpRequest(HttpMethods.GET, Uri(uri)) )
(resp.entity.toString, resp.status)
}
private def _http( hr:HttpRequest )(implicit s:ActorSystem, timeout:Timeout
= 30 seconds) = {
val response: Future[HttpResponse] = (IO(Http) ? hr).mapTo[HttpResponse]
Await.result( response, Duration.Inf )
}
}
I get the following error on the key line IO(...):
[error]
/Users/Greg/git/docker-exp/src/main/scala/com.gwz.dockerexp/Util.scala:66:
inferred type arguments [akka.http.HttpExt] do not conform to method
apply's type parameter bounds [T <: akka.io.IO.Extension]
[error] val response: Future[HttpResponse] = (IO(Http) ?
hr).mapTo[HttpResponse]
This worked great for the Spray libs. How can I modify this to work with
Akka-Http, as the Http object is clearly different?
Thanks!
Greg
