【问题描述】：

我想将多个文件上传到 ios 中的服务器。我有数据作为 NSData，我想将它上传到服务器。我正在使用 alamofire 上传数据。我浏览了他们的文档，但找不到好的答案。我无法理解下面的代码将如何处理 NSData 和多个图像。请提供解决方案。

let fileURL = Bundle.main.url(forResource: "video", withExtension: "mov")

Alamofire.upload(fileURL, to: "https://httpbin.org/post")
    .uploadProgress  progress in // main queue by default
        print("Upload Progress: \(progress.fractionCompleted)")
    
    .downloadProgress  progress in // main queue by default
        print("Download Progress: \(progress.fractionCompleted)")
    
    .responseJSON  response in
        debugPrint(response)
    

【参考方案1】：

使用以下代码使用 Alamofire 上传多张图片。你可以找到它周围的文档here: -

Alamofire.upload(
multipartFormData:  multipartFormData in
    multipartFormData.append(data, name: "imageFile",
                 fileName: "image.jpg", mimeType: "image/jpeg"), 
    multipartFormData.append(data1, name: "image1File",
                fileName: "image1.jpg", mimeType: "image/jpeg")
,
to: "https://httpbin.org/post", //URL,
headers: headers,
encodingCompletion:  encodingResult in
    switch encodingResult 
    case .success(let upload, _, _):
        upload.responseJSON  response in
            debugPrint(response)
        
        upload.uploadProgress(closure:  //Get Progress
                progress in
                    print(progress.fractionCompleted)
            )
    case .failure(let encodingError):
        print(encodingError)
    
)

注意：这是使用 Alamofre 4.0

对于多张图片上传，进度 ios swift

   Alamofire.upload(multipartFormData:  multipartFormData in
            multipartFormData.append(data, withName: "file", fileName: "image.jpg", mimeType:"image/jpeg")
            multipartFormData.append(data1, withName: "file", fileName: "image1.jpg", mimeType:"image/jpeg")
    ,
    to: url, method: .post, headers: headers)  (result) in
        switch result
        case .success(let upload, _, _):
            upload.uploadProgress(closure:  (progress) in
                let progressVal = String(format: "%.2f%%", progress.fractionCompleted * 100)
                print("\(progressVal)")
            )
            
            upload.responseJSON response in
                print(response)
                
            
        case .failure(let error):
            print("Error in upload: \(error.localizedDescription)")
