谷歌驱动器API V3,试图更改文档表和幻灯片以外的文件的所有权

我正在使用google API for google drive,V3使用C#dot net。当我尝试将所有权从我的服务帐户更改为“常规”驱动器帐户(因此它在同一个域中)以外的文件,工作表和幻灯片(如.zip甚至.pdf)以外的文件时,我收到错误消息:

Error: Bad Request. User message: "You can't yet change the owner of this item. (We're working on it.).

我想这与存储配额中没有考虑文档,工作表和幻灯片这一事实有关。 (1)这有解决方法吗? (尝试在上传之前将文件名更改为.doc会导致文件的自动文件转换,之后无用)。 (2)这是否也发生在付费帐户上? (3)Google团队是否真的“正在努力”,因为它在错误消息中说明了?

更新: 这是我正在使用的代码:

    public string UploadFileToDrive(string FilePath, string ParentID)
    {
        try
        {
            Google.Apis.Drive.v3.Data.File body = new Google.Apis.Drive.v3.Data.File();
            string fileNameNoPath = System.IO.Path.GetFileName(FilePath);
            body.Name = "NewFile.ASC"; // some file names such as zip are not acceptable by google drive api
            //body.MimeType = GoogleDriveMimeTypes.GetGenericMimeTypeString();
            if (ParentID != null)
            {
                body.Parents = new List<string>();
                body.Parents.Add(ParentID);
            }


            byte[] byteArray = System.IO.File.ReadAllBytes(FilePath);
            System.IO.MemoryStream Ustream = new System.IO.MemoryStream(byteArray);

            var requestU = _CurrentDriveService.Files.Create(body, Ustream, "");
            requestU.Upload();
            var uploadedFileID = requestU.ResponseBody.Id;

            body.Name = fileNameNoPath;
            //body.MimeType = GoogleDriveMimeTypes.GetGenericMimeTypeString();
            FilesResource.CopyRequest cr = new FilesResource.CopyRequest(_CurrentDriveService, body, uploadedFileID);
            var newFile = cr.Execute();
            var NewFileNameID = newFile.Id;

            DeleteFileFromDrive(uploadedFileID);



            {
                Permission p = new Permission();
                p.Role = "reader";
                p.Type = "anyone";
                PermissionsResource.CreateRequest cc = new PermissionsResource.CreateRequest(_CurrentDriveService, p, NewFileNameID);
                cc.Execute();
            }


            // you can comment out the next block if using Auth client
            // 
            {
                // make main account the owner in order to take its size quota in main account not google service.
                Permission p = new Permission();
                p.Role = "owner";
                p.Type = "user";
                p.EmailAddress = "vizfilesender@gmail.com";


                PermissionsResource.CreateRequest cc = new PermissionsResource.CreateRequest(_CurrentDriveService, p, NewFileNameID);
                cc.TransferOwnership = true; // acknowledge transfer of ownership - must be set to "true" in order for role to change to "owner"
                cc.Execute();
            }





            return NewFileNameID;

        }
        catch (Exception e)
        {
            System.Diagnostics.Debug.WriteLine(e.Message);
            return "";
        }



    }

使用此代码,我可以上传所有文件,更改共享权限,但我无法将所有权更改回google云端硬盘帐户。

我终于找到了答案。我需要冒充其他用户。

    var initializer = new ServiceAccountCredential.Initializer("blablablabla@blabla.iam.gserviceaccount.com")
    {
        Scopes = scope,
        User = "emailToImpersonate@domain"
    };

    var credential = new ServiceAccountCredential(initializer.FromPrivateKey("-----BEGIN PRIVATE KEY-----\n-----END PRIVATE KEY-----\n"));

    var driveService = new DriveService(new BaseClientService.Initializer()
    {
        HttpClientInitializer = credential,
        ApplicationName = ApplicationName
    });

此外,请确保您提供Google服务域范围的委派,如下所示: https://developers.google.com/drive/v2/web/delegation 并且最多需要10分钟才能使更改生效。

这是我一直在寻找的解决方法。
