Alamofire 4 分段请求上传进度

Question

我应该如何使用 Alamofire 4 跟踪我的分段上传请求的进度？

我的 encodingCompletion 处理程序：

encodingCompletion: {
        encodingResult in
        switch encodingResult {
        case .success(let uploadRequest, _, _):
            uploadRequest.uploadProgress {
                p in
                print(p.completedUnitCount, p.totalUnitCount)
            }
            break
        case .failure( _):
            print("Failed to encode upload")
        }
}

我得到的错误是：

不能调用非函数类型'Progress'的值

试试这个：

Alamofire.upload(
        multipartFormData: { multipartFormData in
            multipartFormData.append(URL(string: "http://example.com/url1")!, withName: "one")
            multipartFormData.append(URL(string: "http://example.com/url2")!, withName: "two")
        },
        to: "http://example.com/to",
        encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    debugPrint(response)
                }
                upload.uploadProgress { progress in

                    print(progress.fractionCompleted)
                }
            case .failure(let encodingError):
                print(encodingError)
            }
        }
    )

您需要将 fractionCompleted、totalUnitCount 和 completedUnitCount 转换为 Int 或 Float（取决于您的需要）。

有效！
