Scala Akka HTTP后路由JSON反序列化

我是Scala-Akka httpd的新手，我正在尝试创建一个post路由，它可以接受JSON数据进行序列化并返回另一个JSON响应。到目前为止，我创建了下面的代码，但代码有一些错误，我无法解决它

我还将项目上传到github：

我的要求是：

如何处理输入JSON并发送响应

更新 我用case类更新了路由到point，但在控制台中出错

val httpServerRoute =
     post {
       path("bid-request")
       entity(implicitly[FromRequestUnmarshaller[requestData]]) { request =>
         complete((dataBiddermap ? getBidderData(request)).map(
           _ => StatusCodes.OK
         ))
       }
     }

错误消息：

Error:(95, 25) could not find implicit value for parameter e: akka.http.scaladsl.unmarshalling.FromRequestUnmarshaller[bidder.requestData]
   entity(implicitly[FromRequestUnmarshaller[requestData]]) { request =>
Error:(95, 25) not enough arguments for method implicitly: (implicit e: akka.http.scaladsl.unmarshalling.FromRequestUnmarshaller[bidder.requestData])akka.http.scaladsl.unmarshalling.FromRequestUnmarshaller[bidder.requestData].Unspecified value parameter e.
   entity(implicitly[FromRequestUnmarshaller[requestData]]) { request =>

我在服务器中使用此模式进行

post

请求，希望这有助于：

post {
  decodeRequest {
    entity(as[BidRequest]) { bidRequest =>
      val response: BidResponse = process(bidRequest)

      complete(response)
    }
  }
}

请求和响应类型的封送拆收器在范围内。

这里有很多代码，您能将其缩减为一个吗？您需要一个

post

指令，也许最好先尝试一个简单的

get

端点。还有，错误是什么？它是否不编译，或者它是否编译，但在运行它时，它的行为是否不符合预期？如何运行它，您期望得到什么结果，以及您得到了什么结果？我在compact版本中更新了我的代码，我不知道将请求JSON数据从route指令传递到case类并返回JSON响应的正确过程。我编译了代码，但有错误，因为路由部分不完整。我只需要发布JSON数据并以JSON格式返回

case-class-BidResponse

。请指导我怎么做。我遵循了一些文档，但它会造成更多的混乱。我知道这是一项简单的任务，因为它是关于将JSON发布到POST指令，并以JSON格式返回特定数据，可能会以JSON格式打印ID，并以JSON格式从POST JSON打印横幅w，h。但我是新的，所以我犯了愚蠢的错误，请考虑一下。也许我的代码结构不正确，所以你能告诉我如何处理我的参考JSON数据吗谢谢你的帮助，我在将case类对象值返回到JSON时遇到了另一个错误，

no implicits find for parameter writer jsonwriter

如何转换为JSON response

val responseData=BidResponse（uuid），“XN2ZZQABXJSKKK0JU4QNIZW”，campaignData.bid，选项（“4548”），选项（simpleBanner1））

您的案例类需要一个合适的JSON封送处理程序。详细信息将取决于您使用的JSON库，因此请查看Akka Http文档。如果您仍然有问题，最好单独提问，而不是在这里尝试处理。

post {
  decodeRequest {
    entity(as[BidRequest]) { bidRequest =>
      val response: BidResponse = process(bidRequest)

      complete(response)
    }
  }
}
