喷射 Http Post 请求

Question

这是我试图通过 spray http 创建 Post 请求的代码包裹 org.exadatum.xstream.service.http

import akka.actor.ActorSystem
import akka.util.Timeout
import spray.http._
import spray.httpx.SprayJsonSupport
import spray.client.pipelining._
import spray.json._

import scala.concurrent.duration._
import scala.concurrent.{ExecutionContext, Future}

object Update extends App with SprayJsonSupport with AdditionalFormats{
   implicit val system: ActorSystem = ActorSystem("UpdateJob")
   implicit val executor: ExecutionContext = system.dispatcher
   implicit val timeout: Timeout = Timeout(1.seconds)

   val pipe: HttpRequest => Future[HttpResponse] = sendReceive

   val json = """{
                |  "jobName" : "land",
                |  "appId" : "application_12323121211223",
                |  "status" : "started",
                |  "runningSince" : 1498144649660
                |}""".parseJson.asJsObject()

   pipe(Post("http://localhost:3000/job/v1/updateJobDetails/land",json))
}

我的休息服务是运行 localhost:3000。这样做会导致错误

我尝试了 post Sending post with json using spray?

中提到的解决方案

Answer 1

这很可能是 Scala 库不匹配（根据您引用 hashmap 的具体错误）。尝试使用 scala-library-2.10.jar（来自此处：(run-main-0) java.lang.NoSuchMethodError）

此外，也许您需要正确导入 SprayJsonSupport？ :

import spray.httpx.SprayJsonSupport._
