Question

有人可以展示如何使用google drive api安装应用程序的工作示例代码吗？（access_type =离线）我找到了一些解释，但无法达到工作流程。

由于

Answer 1

好的，我至少使用的不是“已安装的应用程序”，而是“网络应用程序”。这些是要做的步骤：

转到Google Developers Console并创建一个项目。
转到API＆amp;验证
在API上启用Drive API＆amp;推动SDK。

4.在凭据上为Web应用程序创建新的客户端ID（创建您的同意屏幕，尽管我们不会使用它。）

在“创建客户端ID”窗口中，将网址“https://developers.google.com/oauthplayground”添加到AUTHORIZED REDIRECT URIS。

5.转到您在第4号添加的网址

6.单击右侧的齿轮并配置：

OAuth flow: Server-side

Access type: Offline

Use your own OAuth credentials: Tick

Then copy your Client ID & Secret from the console.

7.在左侧，选择Drive API - ＆gt; https://www.googleapis.com/auth/drive，点击授权API

8.将打开一个新窗口，要求您接受Google OAuth ...单击“接受”。

9.单击代币的Exchange授权代码。

10.Copy＆amp;拯救进程和刷新令牌。

代码：

private static DriveService CreateServie(string applicationName)
{
  var tokenResponse = new TokenResponse
  {
    AccessToken = yourAccessToken,
    RefreshToken = yourRefreshToken,
  };

  var apiCodeFlow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
  {
    ClientSecrets = new ClientSecrets
    {
      ClientId = yourClientID,
      ClientSecret = yourClientSecret
    },
    Scopes = new[] { DriveService.Scope.Drive },
    DataStore = new FileDataStore(applicationName)
  });

  var credential = new UserCredential(apiCodeFlow, yourEMail, tokenResponse);

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

  return service;
}

这是我的帮助班，我使用Kinda为你推荐Google Drive。请记住服务帐户不是您。仅仅因为您创建它并不意味着它可以访问您的Google云端硬盘帐户中的文件。服务帐户有自己的实体，有自己的sudu用户。这将创建基本的驱动器服务，您可以使用它来遵循我使用普通Oauth2创建的其他教程

/// <summary>
/// Authenticating to Google using a Service account
/// Documentation: https://developers.google.com/accounts/docs/OAuth2#serviceaccount
/// </summary>
/// <param name="serviceAccountEmail">From Google Developer console https://console.developers.google.com</param>
/// <param name="keyFilePath">Location of the Service account key file downloaded from Google Developer console https://console.developers.google.com</param>
/// <returns></returns>
public static DriveService AuthenticateServiceAccount(string serviceAccountEmail, string keyFilePath)
{

    // check the file exists
    if (!File.Exists(keyFilePath))
    {
        Console.WriteLine("An Error occurred - Key file does not exist");
        return null;
    }

    string[] scopes = new string[] { DriveService.Scope.Drive};     // View analytics data            

    var certificate = new X509Certificate2(keyFilePath, "notasecret", X509KeyStorageFlags.Exportable);
    try
    {
        ServiceAccountCredential credential = new ServiceAccountCredential(
            new ServiceAccountCredential.Initializer(serviceAccountEmail)
            {
                Scopes = scopes
            }.FromCertificate(certificate));

        // Create the service.
        DriveService service = new DriveService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = "Drive API Sample",
        });
        return service;
    }
    catch (Exception ex)
    {

        Console.WriteLine(ex.InnerException);
        return null;

    }
}

你这样称呼它

var x = AuthenticationHelper.AuthenticateServiceAccount("46123799103-6v9cj8jbub068jgmss54m9gkuk4q2qu8@developer.gserviceaccount.com",@"C:\Users\LL\Downloads\Diamto Test Everything Project-e8bf61cc9963.p12");
