如何从授权的 access_token 创建 GoogleCredential? [英] How do I create a GoogleCredential from an authorized access_token?

问题描述

我有一个像这样的 OAuth2 令牌...

I have an OAuth2 token like this...

{{
  "access_token": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "expires_in": "3600",
  "refresh_token": "xxxxxxxxxxxxxxxxxx",
  "token_type": "Bearer",
}}

我正在尝试创建一个 DriveService 对象...

and I'm trying to create a DriveService object...

Service = new DriveService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = "foo",
});

(像这样?)

但我显然没有正确执行此操作，并且无法找到文档.

but I'm clearly not doing this properly and I'm having trouble finding documentation.

当我尝试创建一个 GoogleCredential 以传递给 DriveService

When I attempt to create a GoogleCredential to pass to the DriveService

GoogleCredential credential = GoogleCredential.FromJson(credentialAsSerializedJson).CreateScoped(GoogleDriveScope);

我收到以下异常:

{System.InvalidOperationException:从 JSON 创建凭据时出错.无法识别的凭据类型.

我是否完全以错误的方式处理这个问题?

Am I going about this the wrong way entirely?

(这是示例代码上下文)

推荐答案

我已经设法解决了这个问题.

I have managed to figure this out.

解决方案是使用我的 ClientID 和 ClientSecret 创建一个 Google.Apis.Auth.OAuth2.Flows.GoogleAuthorizationCodeFlow...

The solution was to create a Google.Apis.Auth.OAuth2.Flows.GoogleAuthorizationCodeFlow with my ClientID and ClientSecret...

Google.Apis.Auth.OAuth2.Flows.GoogleAuthorizationCodeFlow googleAuthFlow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer()
{
  ClientSecrets = new ClientSecrets()
  {
    ClientId = ClientID,
    ClientSecret = ClientSecret,
  }
});

还有一个 Google.Apis.Auth.OAuth2.Responses.TokenResponse:

Google.Apis.Auth.OAuth2.Responses.TokenResponse responseToken = new TokenResponse()
{
  AccessToken = SavedAccount.Properties["access_token"],
  ExpiresInSeconds = Convert.ToInt64(SavedAccount.Properties["expires_in"]),
  RefreshToken = SavedAccount.Properties["refresh_token"],
  Scope = GoogleDriveScope,
  TokenType = SavedAccount.Properties["token_type"],
};

并使用每个来创建一个 UserCredential ，依次用于初始化 DriveService...

and use each to create a UserCredential that is, in turn, used to initialize the DriveService...

var credential = new UserCredential(googleAuthFlow, "", responseToken);

Service = new DriveService(new BaseClientService.Initializer()
{
  HttpClientInitializer = credential,
  ApplicationName = "com.companyname.testxamauthgoogledrive",
});

我将 TestXamAuthGoogleDrive 测试工具项目更新为反映这些变化.

I updated the TestXamAuthGoogleDrive test harness project to reflect these changes.
