问题描述
我是akka websocket的新手，正在学习akka客户端websockets https://doc.akka.io/docs/akka-http/current/client-side/websocket-support.html
我正在为我的webrtc janus服务器使用websockets，因为我有URL，我需要向其中发送许多消息并每次收到不同的响应，并根据该响应发送其他消息，我很困惑我们该怎么做通过查看示例代码，我认为我每次需要向服务器发送消息时都需要重复以下代码，但这似乎不正确，正确的方法是什么？
我的例子 websocket服务器正在运行 ws：//0.0.0.0：8188
首先，我将向服务器发送一条消息以启动会话ID
request# 1
{
"janus" : "create","transaction" : "<random alphanumeric string>"
}
服务器将使用会话ID进行响应
response #1
{
"janus": "success","session_id": 2630959283560140,"transaction": "asqeasd4as3d4asdasddas","data": {
"id": 4574061985075210
}
}
然后基于ID 4574061985075210，我将发送另一条消息并接收更多信息
request # 02 {
}
response # 02 {
}

我如何使用Akka客户端Websocket实现这一目标
这是我的代码
import akka.http.scaladsl.model.ws._
import scala.concurrent.Future
object WebSocketClientFlow {
def main(args: Array[String]) = {
implicit val system = ActorSystem()
implicit val materializer = ActorMaterializer()
import system.dispatcher
val incoming: Sink[Message,Future[Done]] =
Sink.foreach[Message] {
case message: TextMessage.Strict =>
println(message.text)
//suppose here based on the server response i need to send another message to the server and so on do i need to repeat this same code here again ?????
}
val outgoing = Source.single(TextMessage("Hello World!"))
val webSocketFlow = Http().webSocketClientFlow(WebSocketRequest("ws://echo.websocket.org"))
val (upgradeResponse,closed) =
outgoing
.viaMat(webSocketFlow)(Keep.right) // keep the materialized Future[WebSocketUpgradeResponse]
.toMat(incoming)(Keep.both) // also keep the Future[Done]
.run()
val connected = upgradeResponse.flatMap { upgrade =>
if (upgrade.response.status == StatusCodes.SwitchingProtocols) {
Future.successful(Done)
} else {
throw new RuntimeException(s"Connection Failed: ${upgrade.response.status}")
}
}
connected.onComplete(println)
closed.foreach(_ => println("closed"))
}
}
