使用Scala Spray httpx编组自定义案例类

Question

我正试图将字符串编组为我所拥有的自定义案例类。这是我试图使用的代码

import spray.httpx.SprayJsonSupport._
import NflWeekJsonProtocol._
    path("playerScore") {
      get {
        parameters('gsisId.as[String] ?, 'week.as[NflWeek] ?, 'playerId.as[String]).as(PlayerScoreRequest) {
          playerScoreRequest : PlayerScoreRequest =>
        }
      }
    }

，这里是我得到的错误:

[error] /home/chris/dev/suredbits-dfs/src/main/scala/com/suredbits/dfs/nfl/scoring/NflPlayerScoringService.scala:40: too many arguments for method parameters: (pdm: spray.routing.directives.ParamDefMagnet)pdm.Out
[error]         parameters('gsisId.as[String] ?, 'week.as[NflWeek] ?, 'playerId.as[String]).as(PlayerScoreRequest) {
[error]                   ^
[error] one error found

NflWeekJsonProtocol表示对case类NflWeek进行序列化的方法。我以为这是所有我需要做的工作，我错过了什么?

编辑:

object NflWeekJsonProtocol extends DefaultJsonProtocol {
  implicit object NflWeekFormat extends RootJsonFormat[NflWeek] {
    override def read(jsValue: JsValue) = {
      jsValue match {
        case JsString(string) => NflWeekFactory.factory(string)
        case _ => throw new RuntimeException("NFLWeek should always be reprsented by a JsString")
      }
    }
    override def write(week: NflWeek) = {
      JsString(week.toString)
    }
  }
}

spray docs建议在使用自定义反序列化器。as(NflWeek)
