我正在使用swagger 2.0.X和akka-http。我想通过swagger用户界面上传文件，但不知道如何将其描述到代码中。我曾尝试使用多部分内容的请求体，但它不起作用

@POST
  @Path("/photo/upload")
  @Operation(
    summary = "Upload photo",
    parameters = Array(
      new Parameter(
        name = "doctype",
        description = "HEADER, describes uploaded document type",
        in = ParameterIn.HEADER,
        required = true,
        schema = new Schema(implementation = classOf[String])
      )
    ),
    requestBody = new RequestBody(
      description = "file",
      content =
        Array(new Content(mediaType = "multipart/form-data", schema = new Schema(`type` = "string", format = "binary")))
    )
  )
  def startPhotoUpload: Route = post {
        headersMap { headers =>
            fileUpload("filename") {
              case (_, fileStream) =>
                val is = fileStream.runWith(StreamConverters.asInputStream())
                handleRequest(
                  documentUploadServiceActorProps,
                  SendPhotoToFurtherUpload(is, headers)
                )
            }
        }
    }
