Java GCP bigquery simba jdbc 连接超时

Question

我尝试使用 simba jdbc 从本地连接 GCP bigQuery 但出现错误。之前我遇到过服务帐户角色权限问题，通过为服务帐户添加必要的角色来解决这些问题

服务帐户具有所需的角色权限，但我仍然收到错误

Answer 1

有两种方法可以验证您的服务帐户。您可能已完成以下两者之一：

OAuth 2.0

和

Service Account based

身份验证 您可能想再次进行身份验证。

这里是一个 URL，用于使用基于服务帐户的身份验证使用 Progress DataDirect BigQuery JDBC 连接器 连接到 Google BigQuery。

jdbc:datadirect:googlebigquery:AuthenticationMethod=serviceaccount;Project=your-project-id;Dataset=your-dataset;[email protected];ServiceAccountPrivateKey=/path/to/json-key-file

要通过 OAuth 2.0 验证服务帐户，需要访问和刷新令牌。要获取令牌，必须创建OAuth ClientID以获取ClientID和获取授权码所需的Client Secret。这是关于如何通过 OAuth 2.0 进行身份验证的完整且详细的指南。
