获取资产库的数据：//asset/asset.MOV

Question

我正在访问我的设备 photoLibrary 的视频。 Everythig工作得很好。现在我有一个视频网址，我想获取视频数据，以便我可以通过REST API上传到服务器，但无法获取视频数据。获得以下错误 -
Error Domain=NSCocoaErrorDomain Code=256 "The file “asset.MOV” couldn’t be opened." UserInfo={NSURL=assets-library://asset/asset.MOV?id=52C33235-2BFE-4FA4-AC8C-5E48DC566847&ext=MOV}

ImagePickerController代码如下 -

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
        {            
         if let image = info[UIImagePickerControllerEditedImage] as? UIImage {// Get the Image    
          }
        else if let videoURL1 = info["UIImagePickerControllerReferenceURL"] as? URL
            {
         self.videoURL = videoURL1
            }            
         picker.dismiss(animated: true, completion: nil)
        }

func imagePickerControllerDidCancel(_ picker: UIImagePickerController)
       {
       picker.dismiss(animated: true, completion: nil)
       }

获取数据的代码如下 -

            do
            {
         let data = try Data(contentsOf: self.videoURL.absoluteURL, options: .alwaysMapped)
                print(data)
            }
            catch
            {
                print(error)
            }

            do
            {
       let data = try Data(contentsOf: self.videoURL.absoluteURL)
             }
            catch
            {
                print(error)
            }
