Question

我正在使用.NET SDK for google drive。我已成功设法在google驱动器上传文件，但是当我使用浏览器登录时无法看到该文件？

这是我的代码：

    private string privKey = "-----BEGIN PRIVATE KEY-----\MYKEYHERE-----END PRIVATE KEY-----\n";

    private string[] scopes = { DriveService.Scope.Drive };
    string serviceAccountEmail = "<myaccounthere>";

    public File uploadToDrive(string uploadFilePath)
    {
        ServiceAccountCredential credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmail)
        {
            Scopes = scopes
        }.FromPrivateKey(privKey));

        BaseClientService.Initializer initializer = new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
        };

        // Create Drive API service.
        var service = new DriveService(initializer);

        if (!string.IsNullOrEmpty(uploadFilePath))
        {
            File fileMetadata = new File();
            fileMetadata.Name = System.IO.Path.GetFileName(uploadFilePath);
            fileMetadata.MimeType = GetMimeType(uploadFilePath);

            try
            {
                System.IO.FileStream uploadStream = new System.IO.FileStream(uploadFilePath, System.IO.FileMode.Open, System.IO.FileAccess.Read);
                FilesResource.CreateMediaUpload request = service.Files.Create(fileMetadata, uploadStream, GetMimeType(uploadFilePath));
                request.ProgressChanged += Upload_ProgressChanged;
                request.ResponseReceived += UploadRequest_ResponseReceived;

                var task = request.UploadAsync();
                task.ContinueWith(t =>
                {

                });
                return request.ResponseBody;


            }
            catch (System.IO.IOException iox)
            {
                return null;
            }
            catch (Exception e) 
            {
                //Log
                return null;
            }
        }
        else
        {
            //Log file does not exist
            return null;
        }
    }

    private string GetMimeType(string fileName)
    {
        string mimeType = "application/unknown";

        string ext = System.IO.Path.GetExtension(fileName).ToLower();

        Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);

        if (regKey != null && regKey.GetValue("Content Type") != null)
            mimeType = regKey.GetValue("Content Type").ToString();

        return mimeType;
    }

    private void Upload_ProgressChanged(IUploadProgress progress)
    {
        Debug.WriteLine(progress.Status + " " + progress.BytesSent);
    }

    private void UploadRequest_ResponseReceived(Google.Apis.Drive.v3.Data.File file)
    {
        Debug.WriteLine(file.Name + " was uploaded successfully");
    }

有没有人碰巧知道我做错了什么？

提前致谢

Answer 1

如果这不起作用，您可以在此related SO question中尝试建议的答案：

由于您使用的是服务帐户，因此将在此服务帐户的驱动器中创建所有文件夹和文件，这些文件夹和文件无法通过Web UI访问，并且将仅限于默认配额。

要在用户的云端硬盘中添加内容，您需要通过常规OAuth 2.0流程来检索此用户的凭据。您可以在此页面上找到有关OAuth 2.0的更多信息：


Retrieve and use OAuth 2.0 credentials。

Quickstart：它可以使用C＃中的快速入门示例。

Using OAuth 2.0 to access Google APIs

希望这有帮助！

是的，你是对的。服务帐户具有此限制。对于任何有同样问题的人，我所做的（使用.NET）来解决这个问题就是启用域范围授权并模拟我需要的帐户。

例如我的服务帐户是srv1@myaccount.gserviceaccount.com impersonates srv1@gmail.com

 ServiceAccountCredential credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer("srv1@myaccount.gserviceaccount.com")
            {
                Scopes = new string[] { DriveService.Scope.Drive },
                User = "srv1@gmail.com"
            }.FromPrivateKey(PRIVATE_KEY));

当我使用srv1@gmail.com登录谷歌驱动器时，我现在可以看到文件

找不到我使用google drive sdk上传到google驱动器的文件
