我正在尝试将字符串编组到我拥有的自定义案例类中。这是我尝试使用的代码

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表示一种对案例类进行序列化的方法NflWeek。我以为这就是我需要做的所有事情才能让它工作，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)
    }
  }
}

喷雾文档建议您在使用自定义反序列化器时需要括号，而不是方括号，.as(NflWeek)
