如何使用Alamofire分段上传来上传音频？

我想使用Alamofire上传和音频文件。 我看到其他问题告诉使用Multipart请求来做到这一点

这是我得到的另一个问题的例子：

  Alamofire.upload( multipartFormData: { multipartFormData in multipartFormData.append(audioRecorder?.url, withName: "iosTest.mp3") //**this "withName:" is it the name of the file? }, to: "https://yourLinkGoesHere", encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in debugPrint(response) } case .failure(let encodingError): print(encodingError) } } ) 

所以当我看一个上面的例子时，我没有得到一些要点才能理解。

1）上面的部分multipartFormData.append(audioRecorder?.url, withName: "iosTest.mp3")什么？ 它是iphone设备中的音频文件名吗？

2）我在哪里可以设置参数和标题？

正常请求的原因我做的是这样的：

 let headers : HTTPHeaders = ["Authorization" : apiKey] let params : [String : Any] = ["my_param" : myParams] Alamofire.request(My_URL!, method: .post, parameters: params, encoding: URLEncoding.httpBody, headers: headers).responseJSON { response in switch response.result { 

所以在multipart中我应该具体的标题和参数？ 请给出multipartFromData.append部分的一些例子。这部分让我很困惑。
谢谢。
