scala - 使用akka-http时如何在另一个actor中完成请求

Question

我正在使用 akka-http 1.0，我想使用定义为的路由

def route: Route = path("") {
  // start actor with requestContext
  // call requestContext.complete(...) in actor with the result
}

我该如何做到这一点？

你可以尝试更好，比如:

package controllers

import akka.actor.{Actor, ActorSystem, Props}
import akka.stream.ActorMaterializer

import scala.concurrent.{Await, Future}
import akka.http.scaladsl.server.Directives._
import akka.stream.ActorMaterializer
import akka.util.Timeout
import akka.pattern.ask
import scala.concurrent.Await
import scala.concurrent.duration._
import scala.io.StdIn
import akka.actor._

import akka.util.Timeout


case object Message

class TestActor(name:String) extends Actor {
  def receive = {
    case Message =>
      sender ! "Testing Ask pattern Approach"
      println(s"hello from $name")

    case _ =>

      println("that was unexpected")
  }
}

object AskTest extends App {

  implicit val system= ActorSystem("myactor")
  implicit val material=ActorMaterializer()

//  implicit val props=Props.empty
implicit val timeout = Timeout(5 seconds)
  implicit val result =system.actorOf(Props(new TestActor("TestingName")),name = "Scala")

   val future3:Future[String]= ask(result ,Message).mapTo[String]
  val results = Await.result(future3, 2 seconds)
  println(results)
}
