Question

以下是我尝试通过spray http创建Post请求的代码包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))
}

我的休息服务正在localhost:3000运行。这会导致错误

我尝试了帖子Sending post with json using spray?

中提到的解决方案

Answer 1

它可能是一个scala库不匹配（根据您引用hashmap的特定错误）。尝试使用scala-library-2.10.jar（从这里：(run-main-0) java.lang.NoSuchMethodError）

另外，您可能需要正确导入SprayJsonSupport吗？：

._

请注意尾随init = clock(); for (i = 0; i < 1024; i++) { //key is randomly generated in the same range of the elements in the tree search(&key, &tree); } end = clock(); //Getting time in usec. time = (double) 1000000 * (end - init) / CLOCKS_PER_SEC;
