如何在 Swift 中使用 AVPlayer 在 iOS 中播放带有 cookie 内容的视频？

我使用下面的实现来播放带有来自服务器的 cookie 内容的视频，但它显示带有十字线的播放图标。我已经参考了link https://stackoverflow.com/questions/39722166/how-to-play-protected-video-content-in-ios-using-avplayer并迅速进行以下实施。但我没有得到任何输出:(

func showVideo(url: String) {
  let videoURL = NSURL(string: url)
  var cookiesArray = [HTTPCookie]()
  guard let cookieArray = UserDefaults.standard.array(forKey: 
  Constants.Object.kCookie) as? [[HTTPCookiePropertyKey: Any]] else { 
  return }

  for cookieProperties in cookieArray {
    if let cookie = HTTPCookie(properties: cookieProperties) {
      cookiesArray.append(cookie)
    }
  } 
  let cookieArrayOptions = [AVURLAssetHTTPCookiesKey: cookiesArray]
  let assets = AVURLAsset(url: videoURL! as URL, options: cookieArrayOptions)
  let item = AVPlayerItem(asset: assets)
  videoPlayer = AVPlayer(playerItem: item)

  self.playerController.player =  self.videoPlayer 
  self.playerController.view.frame = self.view.frame
  self.present(self.playerController, animated: true, completion: nil)
  self.playerController.player?.play()
 }

请帮我解决这个问题，该实施有什么问题。

提前致谢！ :)

经过很多方法之后，我终于得到了对我有用的解决方案：

     func showVideo(url: String) {
      let videoURL = NSURL(string: url)
      let cookiesArray = HTTPCookieStorage.shared.cookies! //Stored Cookies of your request
      let values = HTTPCookie.requestHeaderFields(with: cookiesArray)// Returns a dictionary of header fields corresponding to a provided array of cookies.ex.["Cookie":"your cookies values"]
      let cookieArrayOptions = ["AVURLAssetHTTPHeaderFieldsKey": values]
      let assets = AVURLAsset(url: videoURL! as URL, options: cookieArrayOptions)
      let item = AVPlayerItem(asset: assets)
      videoPlayer = AVPlayer(playerItem: item)

      self.playerController.player =  self.videoPlayer 
      self.playerController.view.frame = self.view.frame
      self.present(self.playerController, animated: true, completion: nil)
      self.playerController.player?.play()
     }
