Question

我正在尝试使用akka http生成PUT请求，我的休息服务端点在使用curl完成时按预期工作，但在我通过创建Http连接生成它时显示超时错误。

import akka.actor.ActorSystem
import akka.http.scaladsl.Http
import akka.http.scaladsl.model._
import akka.stream.ActorMaterializer
import de.heikoseeberger.akkahttpcirce.CirceSupport
import io.circe.Json
import org.joda.time.DateTime

case class JobDetails (jobName: String, appId: Option[String]=None, status: Option[String]=None,runningSince:Option[Long]=None)

trait UpdateJobStatus extends CirceSupport with Config {


  def UpdateJobDetails(jobDetails :JobDetails) {


    implicit val actorSystem = ActorSystem("update")
    implicit val materializer: ActorMaterializer = ActorMaterializer()

    val DetailsList = List(
      ("jobName",Json.fromString(jobDetails.jobName)),
      ("appId",Json.fromString(jobDetails.appId.get)),
      ("status",Json.fromString(jobDetails.status.get)),
      ("runningSince",Json.fromLong(DateTime.now.getMillis)))

    val jobDetailJson:Json = Json.fromFields(DetailsList)


    val endpoint =Uri.from(scheme = "http",host = httpHost,port = 9000,path = "/updateJobDetails/TestJob")

    val updateRequest = HttpRequest(
      HttpMethods.PUT,
      uri = endpoint,
      entity = HttpEntity(MediaTypes.`application/json`, jobDetailJson.toString()))

    Http().singleRequest(updateRequest)


  }
}

object Test extends App with UpdateJobStatus{

  val test = JobDetails("TestJob",Some("1234"),Some("Killed"),Some(21))
 UpdateJobDetails(test)

}

错误：

虽然

curl -v -H "Content-Type: application/json" \
-X PUT http://0.0.0.0:9000/updateJobDetails/TestJob \
-d '{"jobName":"TestJob","appId":"1234","status":"Killed","runningSince":1}'

Answer 1

您正在创建请求，结果为Future[HttpResponse]。

我认为你应该直接处理Future完成，或者通过将结果传递给一个actor，然后接收一个类型为HttpResponse的消息。

可以找到一个示例here。

如果这仍然可以让您超时，我建议您使用网络流量监控器Wireshark深入了解。
