如何在Alamofire 4.0中添加帶有標籤進度條的上傳進度百分比

我試圖通過Alamofire 4.0將視頻上傳到服務器，並且我想添加進度條以顯示上傳過程中上傳過程的百分比，我如何通過Alamofire上傳的相同功能來做到這一點。如何在Alamofire 4.0中添加帶有標籤進度條的上傳進度百分比

我的上傳功能的代碼：

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") 
        })

要直接從AlamoFire文檔引用：

上傳進度

當你的用戶正在等待他們上傳來完成，有時可以方便地顯示上傳到用戶的進度。任何 UploadRequest都可以使用uploadProgress和downloadProgress API報告上傳進度和響應數據的下載進度。

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) 
    }

其中是該行中視頻的URL？ let fileURL = Bundle.main.url（forResource：「video」，withExtension：「mov」） –

它意味着獲取名爲video.mov的文件在您的主包中的URL。 – bubuxu

這是示例代碼，而不是特定於您問題的代碼。該行爲應用程序包創建名爲「video.mov」的文件的文件url。 –

請檢查一下。

  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)

fullLink我必須把它作爲字符串或urlrequest，因爲在第二種情況下，它給我null，所以視頻不上傳 –

，這部分我不明白，我如何處理，如果我有我的代碼2參數以上。 // let data =（value as！String）.data（using：String.Encoding.utf8）！ } –

fullLink = String –
