允许组织主帐号使用标签

在资源项目中创建 Data Catalog 标记模板后，您可以向主帐号授予 Data Catalog tagTemplateUser 角色。这样一来，他们就可以创建元数据，即使用模板来标记数据资源。如需了解详情，请参阅将标记附加到 GCP 资源。

下一部分将介绍如何授予 tagTemplateUser 角色。

授予 tagTemplateUser 角色

控制台

控制台

如需将 Data Catalog tagTemplateUser 角色授予项目的主帐号，请执行以下操作：

  1. 在 Google Cloud Console 中转到 IAM，然后点击主帐号列表右侧的修改 () 按钮。

  2. 在修改权限对话框中，点击 添加其他角色，然后点击选择角色下拉列表。

  3. 在 过滤条件框中，插入 Data Catalog TagTemplate User 以显示此角色，然后选择此角色并点击保存。

在尝试此示例之前，请按照《Data Catalog 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 Data Catalog Node.js API 参考文档。

// Import the Google Cloud client library.

REST 和命令行

REST 和命令行

如果您无法使用针对您的语言的 Cloud 客户端库或者您想要使用 REST 请求来测试 API，请参阅以下示例并参阅 Data Catalog REST API 文档。

在使用任何请求数据之前，请先进行以下替换：

  • project-id：GCP 项目 ID
  • template-id：标记模板 ID

HTTP 方法和网址： 

POST https://datacatalog.googleapis.com/v1/projects/project-id/locations/us-central1/tagTemplates/template-id:setIamPolicy

请求 JSON 正文：

{
  "policy":{
    "bindings":[
      {
        "role":"roles/datacatalog.tagTemplateUser",
        "members":[
          "user:username@gmail.com"
        ]
      }
    ]
  }
}

如需发送您的请求，请展开以下选项之一：

您应该会收到类似以下内容的 JSON 响应：

{
  "version":1,
  "etag":"xxxxx.....",
  "bindings":[
    {
      "role":"roles/datacatalog.tagTemplateUser",
      "members":[
        "user:username@gmail.com"
      ]
    }
  ]
}
