我正在尝试通过Alamofire 4.0将视频上传到服务器，我想添加进度条以显示上传过程中上传过程的百分比，我是如何通过Alamofire上传的相同功能来实现的。
我的上传功能代码：
Alamofire.upload(multipartFormData: { multipartFormData in
multipartFormData.append(url.absoluteURL!, withName: "videoFile", fileName: "alaa", mimeType: "mov")
multipartFormData.append("video".data(using: .utf8)!, withName: "load")
multipartFormData.append("record".data(using: .utf8)!, withName: "type")
}, with: URL, encodingCompletion: { (result) in
// code
print("uploaded")
})

直接引用AlamoFire文档：
上传进度
当您的用户正在等待他们的上传完成时，有时候 可以方便地显示上传到用户的进度。任何 UploadRequest可以报告上传进度和下载进度 使用uploadProgress和downloadProgress API的响应数据。
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)
}

请检查一下。
var imgData = Data()
if image != nil {
imgData = UIImageJPEGRepresentation(image!, 1.0)!
}
Alamofire.upload(multipartFormData:{ multipartFormData in
multipartFormData.append(imgData, withName: "image", fileName: "imagefilename", mimeType: "image/jpeg")
for (key, value) in param {
//let data = (value as! String).data(using: String.Encoding.utf8)!
let data = (value as AnyObject).data(using: String.Encoding.utf8.rawValue)
multipartFormData.append(data!, withName: key as! String)
}
},
usingThreshold:UInt64.init(),

method:.post,
headers:[:],
encodingCompletion: { encodingResult in
switch encodingResult {

upload.uploadProgress { progress in // main queue by default
print("Upload Progress: \(progress.fractionCompleted)")
}
upload.responseJSON { response in
debugPrint(response)
if let TempresponseDict:NSDictionary = response.result.value as? NSDictionary {
if (TempresponseDict.object(forKey: "response") as? String)?.caseInsensitiveCompare("success") == .orderedSame {
CompletionHandler(true, TempresponseDict)
}
else {
var statusCode = response.response?.statusCode
if let error = response.result.error as? AFError {

switch error {
