Question

我想使用一个演员的喷涂客户端发出一个Web请求，这个Web请求需要一个参数，该参数必须是接收消息的一部分。为了做到这一点，我创建了一个案例类，如：

case class MessageWithParam(param: String)

演员看起来像这样：

import akka.actor.{Actor, ActorLogging}
import akka.util.Timeout
import spray.client.pipelining._
import spray.http.{FormData, HttpRequest, HttpResponse}

import scala.concurrent.Future
import scala.concurrent.duration._
import scala.util.{Failure, Success}
import scala.xml.XML

import org.example.MessageWithParam

class WebCall extends Actor with ActorLogging  {
  import context.dispatcher
  implicit val timeout: Timeout = Duration(5, SECONDS) // TODO Eliminate magic number
  val pipeline: HttpRequest => Future[HttpResponse] = sendReceive

  def receive = {
    case MessageWithParam(param) => {
      val sendingActor = sender()
      val data =  Seq("Param" -> param)
      val request = Post("http://my.server.com/request",FormData(data))

      pipeline(request) onComplete {
        case Success(httpResponse: HttpResponse) => {
          ...
        }
        case Failure(error) => {
          ...
        }
      }
    }
  }
}

我的问题是，每当消息是一个字符串时，例如：

 def receive = {
   case "Message" => {
     ...
 }

服务电话已被取消。但是，如果我使用案例类以便能够参数化消息，那么Web调用就会超时（但我用wireshark检查过），甚至没有建立与服务器的连接。

调用消息的代码：

import akka.actor.{ActorSystem, Props}
import akka.testkit.{DefaultTimeout, ImplicitSender, TestKit}
import org.example.WebCall
import org.example.MessgeWithParam
import org.scalatest.{BeforeAndAfterAll, Matchers, WordSpecLike}
import scala.concurrent.duration._

class WebCallTest extends TestKit(ActorSystem("WebCallTest",
   ConfigFactory.parseString(TestConfig.config)))
   with DefaultTimeout with ImplicitSender
   with WordSpecLike with Matchers with BeforeAndAfterAll {

   val webCallRef = system.actorOf(Props(classOf[WebCall]))

   override def afterAll {
     shutdown()
   }

   "A WebCall" should {
     "Respond to a 'example' call with a 'success' message" in {
       within(5000 millis) {
         webCallRef ! MessgeWithParam("example")
         expectMsg("success")
       }
     } 
   } 
}

当消息是案例类时，我处于不同的上下文中吗？
