如何使用Alamofire将跑步信息上传到Strava运动员的个人资料

Question

我正在尝试向应用添加功能，以允许用户将运行上传到其Strava配置文件。当前，运行以gpx文件形式存储在应用程序的Documents目录中，尽管我知道如何访问它们，但Alamofire请求的语法存在问题。我的代码如下：

func getDocumentsDirectory() -> URL {
  let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
  let documentsDirectory = paths[0]
  do {
    let fileURLs = try FileManager.default.contentsOfDirectory(at: documentsDirectory, includingPropertiesForKeys: nil)
    print("Directory contents: \(fileURLs)")
  } catch {
    print("Error while enumerating files \(documentsDirectory.path): \(error.localizedDescription)")
  }
  return documentsDirectory
}

var path = getDocumentsDirectory()
path = path.appendingPathComponent("Sample_Activity.gpx")
print("\nPath component points to: \(path)\n")

/* ======================== Begin Strava API Upload =========================== */


Alamofire.upload(multipartFormData:{ multipartFormData in

  multipartFormData.append("run".data(using: String.Encoding.utf8)!, withName: "activity_type")
  multipartFormData.append(path, withName:"activity")
  multipartFormData.append("gpx".data(using: String.Encoding.utf8)!, withName: "data_type")
        },
           usingThreshold:UInt64.init(),
           to:"https://www.strava.com/api/v3/uploads",
           method:.post,
           headers:["Authorization": "Bearer <token>"],
             encodingCompletion: { encodingResult in
               switch encodingResult {
               case .success(let upload, _, _):
                 upload.responseJSON { response in
                   debugPrint(response)
                 }
               case .failure(let encodingError):
                 print(encodingError)
               }
        })

    }

我收到了与Postman合作的请求，但没有与Alamofire合作的请求。这是邮递员成功请求的照片：https://i.stack.imgur.com/oxQcx.png

使用Alamofire时，每次获得400状态，结果如下：

[Data]: 88 bytes
[Result]: SUCCESS: {
    errors =     (
                {
            code = empty;
            field = data;
            resource = Upload;
        }
    );
    message = "Bad Request";
}

标题页下的一个元素是授权令牌，与Alamofire请求中的元素相同。非常感谢您的帮助。
