【问题描述】：

我正在尝试将多个图像和视频从库上传到 url。 evertying 工作正常，除了，响应只打开一个文件。我选择两个不同的图像进行实验，但响应仅适用于数组中的最后一个图像。这是我的上传功能..

 func upload() 
    var mediaData = Data()
    var fname = ""
    var mimetype = ""
    let url = URL(string: "https://myurl.com/api/attachment/upload")
        let headers: HTTPHeaders = [
            "Authorization": "my Authorization Token",
            "Content-type": "multipart/form-data"
        ]

        Alamofire.upload(multipartFormData:  multipartFormData in
               for n in 0..<self.array.count
                    mediaData = self.array[n].data
                    if self.array[n].type == "image"
                        fname = "resim\(n).jpeg"
                        mimetype = "image/jpeg"
                    else
                        fname = "video\(n).mp4"
                        mimetype = "video/mp4"
                    
                    multipartFormData.append(mediaData, withName: "files", fileName: fname, mimeType:mimetype)
                


        ,
          to: url!, method: .post, headers: headers)  (result) in
            switch result
            case .success(let upload, _, _):
                upload.uploadProgress(closure:  (progress) in

                    print("uploding: \(progress.fractionCompleted)")
                )


                upload.responseJSON response in
                    print(response)
                    self.hud.dismiss()

                    if let err = response.error
                        print(err)
                        return
                    

                
            case .failure(let error):
                print("Error in upload: \(error.localizedDescription)")

            
        

这就是服务器返回的响应。

SUCCESS: 
files =     (
            
        "local_name" = BaN9x05lU8jNQPJ30RfbT4rqismLp7LE45sHezHvI;
        "real_name" = "resim1.jpeg";
    
);

知道我在哪里犯错了吗？

【参考方案1】：

check below code

var dataArray = [("name":"unicorn1","imageData":imgData1),("name":"unicorn2","imageData":imgData2)] 阿拉莫火.上传（ multipartFormData: multipartFormData in

        for dat in dataArray 

           multipartFormData.append(dat.imageData, withName: dat.name)
        

    ,
    to: "https://httpbin.org/post",
    encodingCompletion:  encodingResult in
        switch encodingResult 
        case .success(let upload, _, _):
            upload.responseJSON  response in
                debugPrint(response)
            
        case .failure(let encodingError):
            print(encodingError)
        
    
)

【讨论】：

感谢您的考虑，但我的问题是数组不是静态的。可能是一个或十个。

我编辑了答案，如果有帮助，请立即检查，然后请投票

感谢您的关心，但我找到了解决方案。

【参考方案2】：

我解决了将"files[\(n)]" 更改为代码部分的问题

 multipartFormData.append(mediaData, withName: "files", fileName: fname, mimeType:mimetype)

然后问题解决了。

func upload() 
var mediaData = Data()
var fname = ""
var mimetype = ""
let url = URL(string: "https://myurl.com/api/attachment/upload")
    let headers: HTTPHeaders = [
        "Authorization": "my Authorization Token",
        "Content-type": "multipart/form-data"
    ]

    Alamofire.upload(multipartFormData:  multipartFormData in
           for n in 0..<self.array.count
                mediaData = self.array[n].data
                if self.array[n].type == "image"
                    fname = "resim\(n).jpeg"
                    mimetype = "image/jpeg"
                else
                    fname = "video\(n).mp4"
                    mimetype = "video/mp4"
                
                multipartFormData.append(mediaData, withName: "files[\(n)]", fileName: fname, mimeType:mimetype)
            


    ,
      to: url!, method: .post, headers: headers)  (result) in
        switch result
        case .success(let upload, _, _):
            upload.uploadProgress(closure:  (progress) in

                print("uploding: \(progress.fractionCompleted)")
            )


            upload.responseJSON response in
                print(response)
                self.hud.dismiss()

                if let err = response.error
                    print(err)
                    return
                

            
        case .failure(let error):
            print("Error in upload: \(error.localizedDescription)")
