Scala POST请求有时会在Akka http程序中命中错误的端点

我有一个AKKAHTTP2服务器来处理http请求

在任一端点上，我将转换为案例类别A或B：

case class caseClassA(data: String, eventID: String)
case class caseClassB(data: String, otherData: JsObject)

我有这样一个routes对象：

   val routes = {
     logRequestResult("akka-http-microservice") {        
       pathPrefix("some_endpoint")
        (post & entity(as[caseClassA])) {
        Request =>
          val future = someFunction(Request)
            complete {
              future.map(result =>
                result
              )
            }
        } ~
        pathPrefix("other_endpoint") {
          (post & entity(as[caseClassB])) {
          Request =>
            val future = otherFunction(Request)
              complete {
                future.map(result =>
                  result
                ) 
              }
            }
          }
        }

问题：有时，当使用Alamofire从iOS应用程序调用时，我在使用caseClassB可转换JSON对象请求

其他\U端点

时，会收到错误响应，错误数据发送到

某些\U端点

正如您通过缺少

eventID

所看到的，这正试图转换为caseClassA。上面输出中的两个请求都表明我正在尝试命中其他的\u端点。当我使用相同的数据从Postman调用此端点时，它在100%的时间内工作

给出了什么？

从上面的评论中可以看出，问题是

“某些端点”

的代码周围缺少大括号（

{}

）。以下是更正后的代码块：

val routes = {
  logRequestResult("akka-http-microservice") {        
    pathPrefix("some_endpoint") {
      (post & entity(as[caseClassA])) {
         Request =>
         val future = someFunction(Request)
         complete {
           future.map(result =>
             result
           )
         }
       }
     } ~
     pathPrefix("other_endpoint") {
       (post & entity(as[caseClassB])) {
         Request =>
         val future = otherFunction(Request)
         complete {
           future.map(result =>
             result
           ) 
         }
       }
     }
   }

---

这会像pathPrefix（“some_endpoint”）指令后缺少一组大括号一样简单吗？是的。经过多次测试，这似乎是导致间歇性故障的原因。奇怪的是，sbt/IntelliJ没有出现语法错误的问题。该死的花括号。
