Akkahtp：如何在使用mutlpart upload（实体（如[Multipart.FormData]）时从路径访问捕获的值

我试图在上传文件时从path访问捕获的值，但无法了解实现的想法

以下是示例代码：

trait TestRoute extends {
  val regEx = """(\w+)""".r
  def testRoute: Route = path("testing" / regEx / regEx / regEx){
    post {
      //How do i Access (captured regex from the path) inside entity
      entity(as[Multipart.FormData]) { fileData => {
        complete {
           "UpLoadDOne"
        }  
       }
    }
   }
}

谢谢你的帮助

如果使用喷雾剂，您将需要：

import spray.routing.PathMatchers.Segment

trait TestRoute extends {

  def testRoute: Route = path("testing" / Segment / Segment / Segment){ case (A, B, C) =>
    post {
      entity(as[Multipart.FormData]) { fileData =>
        complete {
          "UpLoadDOne"
        }
      }
    }
  }
