NSURLSession - DownloadTask不能與某些URL

這裏工作的代碼：NSURLSession - DownloadTask不能與某些URL

let url = NSURL(string: "http://a337.phobos.apple.com/us/r30/Music/d5/a8/6b/mzi.msfqeogi.aac.p.m4a") 
let downloadTask = self.downloadSession.downloadTaskWithURL(url!) 
downloadTask.resume()

- >確定

與更換網址： http://s1mp3.r41s223.vcdn.vn/d3f549abeeef07b15efe/2937387453157939420?key=c2WuQChtsmR9yfdz9I-jnw&expires=1480695588&filename=Only%20Love%20-%20Trademark.mp3

- >它做沒有工作;沒有任何反應

默認情況下，從iOS 9開始，所有連接都必須是https。如果第二個網址不支持https：//則下載失敗。

我建議您檢查您的錯誤代碼從下載回來

請plist中

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> 
<plist version="1.0"> 
<dict> 
    <key>NSAllowsArbitraryLoads</key> 
    <true/> 
    <key>NSExceptionDomains</key> 
    <dict> 
     <key>akamaihd.net</key> 
     <dict> 
      <key>NSExceptionRequiresForwardSecrecy</key> 
      <false/> 
      <key>NSIncludesSubdomains</key>

     <key>fbcdn.net</key> 
     <dict> 
      <key>NSExceptionRequiresForwardSecrecy</key>

      <key>NSIncludesSubdomains</key> 
      <true/> 
     </dict> 
     <key>graph.facebook.com</key> 
     <dict> 
      <key>NSExceptionAllowsInsecureHTTPLoads</key> 
      <true/> 
      <key>NSExceptionRequiresForwardSecrecy</key> 
      <false/> 
      <key>NSIncludesSubdomains</key> 
      <true/> 
     </dict> 
    </dict> 
</dict> 
</plist>

然後使用Alamofire 4.0雨燕3.0

使用以下方法

添加，您可以下載任何東西，例如。 PDF

// Mark:- Download File 
    func DownloadFile(strFileUrl : String, strFileName : String, success:@escaping (_ strResultURL: String) -> Void , failure:@escaping (_ responseObject:AnyObject) -> Void) { 
     let destination: DownloadRequest.DownloadFileDestination = { _, _ in 
      let documentsURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0] 
      let fileURL = documentsURL.appendingPathComponent("\(strFileName)") 

      return (fileURL, [.removePreviousFile, .createIntermediateDirectories]) 
     } 

     Alamofire.download(strFileUrl, to: destination).response { response in 

       if SVProgressHUD.isVisible() { 
        SVProgressHUD.dismiss() 
       } 

       if response.error == nil { 
        success("\(response.destinationURL!)") 
       } 
       else { 
        failure(response.error as AnyObject) 
       } 
      }.downloadProgress { (progress) in 
       print("Download Progress: \(progress.fractionCompleted)") 
       SVProgressHUD.showProgress(Float(progress.fractionCompleted), status: AppAlertMsg.KDownloadingPDFs) 
     } 
    }
