Question

我是使用oauth 2.0的新手，所以我按照谷歌的教程使用oauth 2.0访问Google Analytics 我在google开发人员控制台中创建了一个OAuth客户端，并使用此代码访问分析：

  httpTransport = GoogleNetHttpTransport.newTrustedTransport();
      dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);
      // authorization
      Credential credential = authorize();

      // set up global Oauth2 instance
      oauth2 =
          new Oauth2.Builder(httpTransport, JSON_FACTORY, credential).setApplicationName(
              APPLICATION_NAME).build();


      Analytics analytics = new Analytics.Builder(httpTransport, JSON_FACTORY, credential).build();

授权方法：

 private static Credential authorize() throws Exception 
  {
    // load client secrets
    clientSecrets =
        GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(OAuth2Sample.class.getResourceAsStream("/client_secrets.json")));
    if (clientSecrets.getDetails().getClientId().startsWith("Enter") || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) 
    {
      System.out.println("Enter Client ID and Secret from https://code.google.com/apis/console/ "
          + "into oauth2-cmdline-sample/src/main/resources/client_secrets.json");
      System.exit(1);
    }
    // set up authorization code flow
    GoogleAuthorizationCodeFlow flow =
        new GoogleAuthorizationCodeFlow.Builder(httpTransport, JSON_FACTORY, clientSecrets, SCOPES)
            .setDataStoreFactory(dataStoreFactory).build();
    // authorize
    return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("[my email]");
  }

我从我在Google开发者控制台中创建的Auth 2.0客户端下载JSON文件：

 {
    "installed":
    {"auth_uri":"https://accounts.google.com/o/oauth2/auth",
    "client_secret":[my clients secret],
    "token_uri":"https://accounts.google.com/o/oauth2/token",
    "redirect_uris":["urn:ietf:wg:oauth:2.0:oob","oob"],
    "client_id": [my client id],
    "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs"
    }
    }

我使用了代码，结果是：

com.google.api.client.auth.oauth2.TokenResponseException: 400 Bad Request
{
  "error" : "invalid_grant"
}

你知道我遗失了什么吗？非常感谢你的帮助！
