已安裝的應用程序的Google Drive Api c＃

Question

有人可以展示如何使用谷歌驅動器api安裝應用程序的工作示例代碼？ （access_type = offline）我找到了一些解釋，但無法進入工作流程。

謝謝

Answer 1

好吧，我至少使用的不是“安裝的應用程序”，而是“網絡應用程序”。 這些是要做的步驟：

1. 轉到Google Developers Console並創建一個項目。

2. 轉到API和Auth

3. 在API上啟用Drive API和Drive SDK。

4.在憑據上為Web應用程序創建新的客戶端ID（創建您的同意屏幕，盡管我們不會使用它。）

在“創建客戶端ID”窗口中，將網址“ https://developers.google.com/oauthplayground ”添加到AUTHORIZED REDIRECT URIS。

5.轉到您在第4號添加的網址

6.單擊右側的齒輪並配置：

OAuth flow: Server-side

Access type: Offline

Use your own OAuth credentials: Tick

Then copy your Client ID & Secret from the console.

7.在左側，選擇Drive API - > https://www.googleapis.com/auth/drive ，單擊授權API

8.將打開一個新窗口，要求您接受Google OAuth ...單擊“接受”。

9.單擊令牌的Exchange授權代碼。

10.Copy＆Save the Acess＆Refresh令牌。

編碼：

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;
}

這是我的助手課程，我使用Kinda為你推薦Google Drive。 請記住服務帳戶不是您。 僅僅因為您創建它並不意味着它可以訪問您的Google雲端硬盤帳戶中的文件。 服務帳戶有自己的實體，有自己的sudu用戶。 這將創建基本的驅動器服務，您可以使用它來遵循我使用普通Oauth2創建的其他教程

/// <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;

    }
}

你這么稱呼它

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