获取数据政策的 IAM 政策

从 BigQuery Data Policy API 获取指定数据政策资源的 IAM 政策。这有助于审核哪些成员在政策中具有哪些角色。

代码示例

Node.js

试用此示例之前，请按照 BigQuery 快速入门：使用客户端库中的 Node.js 设置说明进行操作。 如需了解详情，请参阅 BigQuery Node.js API 参考文档。

const client = new DataPolicyServiceClient();

/**
 * Get the IAM policy for a specified data policy resource from the BigQuery Data Policy API.
 * This is useful for auditing which members have which roles on the policy.
 *

 * @param {string} projectId Google Cloud Project ID (For example, 'example-project-id')
 * @param {string} location Google Cloud Location (For example, 'us-central1')

      console.error(
        `Error: Data Policy '${dataPolicyId}' not found in location '${location}' of project '${projectId}'. ` +
