如何使用Alamofire分段上传来上传音频？ [英] How to upload audio with Alamofire multipart upload?

问题描述

我想使用 Alamofire 上传音频文件。我看到其他问题告诉使用Multipart请求这样做

I want to upload and audio file with using Alamofire. I see other questions which are telling to use Multipart request to do that

以下是我从其他问题中得到的示例：

 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)
        }
    }
)

因此，当我查看上面的示例时，我没有得到几点理解。

So when i look at an example above and i did not get a few points to understand.

1）什么是withName：部分是 multipartFormData.append（audioRecorder？.url，withName：iosTest.mp3）以上？它是iphone设备中的音频文件名吗？

1) what is "withName:" in this part multipartFormData.append(audioRecorder?.url, withName: "iosTest.mp3") above? Is it an audio file name in iphone device?

2）我在哪里可以设置参数和标题？

2) Where can i set parameters and headers?

在正常请求中导致我的行为是这样的：

Cause in normal request what i do is like this :

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中我应该在哪里使用特定的标题和参数？请给出一些 multipartFromData.append 部分的例子。这部分让我很困惑。
谢谢。

So in multipart where should i specific headers and params? Please give some example for multipartFromData.append part.This part is quite confusing for me.
Thanks.

您好我正在使用此代码将歌曲图像和m4a文件上传到我的服务器。
希望这对你有用。

Hi im using this code to upload song image and m4a file to my server . Hope this work for you.
