java.lang.RuntimeException:从scala工作表测试类时,没有启动应用程序错误

我想通过从scala工作表运行它来测试一个类。运行此测试脚本时:

import ping.GcmRestServer

val server = new GcmRestServer("AIzaSyCOn...")
server.send(List("dcGKzDg5VOQ:APA91bHNUDaBj01th..."), Map(
  "message" -> "Test Message",
  "title" -> "Test Title"
))

测试类GcmRestServer是

package ping

import play.api.Logger
import play.api.libs.ws.WS
import play.api.libs.json.Json
/**
  * Created by Lukasz on 26.02.2016.
  */
class GcmRestServer(val key: String) {

  def send(ids: List[String], data: Map[String, String]) = {
    import play.api.Play.current
    import scala.concurrent.ExecutionContext.Implicits.global

    val body = Json.obj(
      "registration_ids" -> ids,
      "data" -> data
    )

    WS.url("https://android.googleapis.com/gcm/send")
      .withHeaders(
        "Authorization" -> s"key=$key",
        "Content-type" -> "application/json"
      )
      .post(body)
      .map { response => Logger.debug("Result: " + response.body)}
  }
}

给出以下结果:

import ping.GcmRestServer

server: ping.GcmRestServer = ping.GcmRestServer@34860db2
java.lang.RuntimeException: There is no started application
    at scala.sys.package$.error(test.sc2.tmp:23)
    at play.api.Play$$anonfun$current$1.apply(test.sc2.tmp:82)
    at play.api.Play$$anonfun$current$1.apply(test.sc2.tmp:82)
    at scala.Option.getOrElse(test.sc2.tmp:117)
    at play.api.Play$.current(test.sc2.tmp:82)

    at #worksheet#.get$$instance$$res0(test.sc2.tmp:4)
    at #worksheet#.#worksheet#(test.sc2.tmp:19)

有人可以解释一下我做错了什么,以及如何解决这个问题?

import play.api.Play.current行需要正在运行的Play应用程序。

我从未使用过scala工作表,但似乎也存在同样的问题。

在测试中,解决方案是运行假应用程序,如written in the documentation

答案 1 :(得分:0)

您正在使用需要运行播放应用程序的播放 WS。只需用这样的代码开始:

import play.api.libs.ws.WS
import play.api.{Play, Mode, DefaultApplication}
import java.io.File
import play.api.Logger
import play.api.libs.json.Json
import scala.concurrent.ExecutionContext.Implicits.global



class GcmRestServer(val key: String) {

  val application = new DefaultApplication(
    new File("."),
    Thread.currentThread().getContextClassLoader(),
    None,
    Mode.Dev
  )

  def send(ids: List[String], data: Map[String, String]) = {

    val body = Json.obj(
      "registration_ids" -> ids,
      "data" -> data
    )

    WS.client(application).url("https://android.googleapis.com/gcm/send")
      .withHeaders(
        "Authorization" -> s"key=$key",
        "Content-type" -> "application/json"
      )
      .post(body)
      .map { response => Logger.debug("Result: " + response.body)}
  }
}

或者,如果您不想使用 WS.Client(application),您可以运行 Play.start(application),使用 import play.api.Play.current 导入它,然后 WS.url 将起作用。
