如何以编程方式更新 PowerBI 数据集的 Azure SQL 数据源凭据？

Question

我有一个 Azure Devops 流程，它使用服务原则从 .pbix 文件部署 Power BI 报告并更新数据源以指向生产 Azure SQL 服务器。

结果是部署了报表和数据集并更新了连接，但是凭据为空（用户名和密码），因此为了使其可用，必须有人登录 Power BI 服务，打开数据集并更新凭据，这意味着我们的 CI/CD 过程涉及手动步骤。

我需要帮助通过代码更新新数据源的源凭据，这样就不需要这个手动过程了

任何建议都会有很大帮助。谢谢。

这是一个示例 PowerShell 脚本，之后使用 Microsoft Power BI Cmdlets, which will patch the credentials of the dataset and commented at the end are few rows, which will refresh the dataset（如果需要，取消注释）。只需将顶部的 x-es 替换为实际值（工作区和数据集名称、应用程序 ID 等）。

<#

Patch the credentials of a published report/dataset, so it can be refreshed.
