Akka HTTP：使用分段上传时如何从路径访问捕获值（实体（as[Multipart.FormData]））

Question

我试图在上传文件时从路径访问捕获的值，但无法了解实现的想法。

示例代码如下：

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"
        }  
       }
    }
   }
}           

http://localhost:9000/testing/A/B/C

感谢您的帮助！

如果你使用喷雾，你需要类似的东西：

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"
        }
      }
    }
  }
