Cloud Billing Budget API 的访问权限控制

Google Cloud 提供 Identity and Access Management (IAM)，可让您授予对特定 Google Cloud 资源的更细化访问权限，并防止对其他资源进行不必要的访问。IAM 允许您采用最小权限安全原则，因此您只需授予对您的资源的必要访问权限即可。

IAM 允许您通过设置 IAM 政策来控制谁（用户）对哪些资源具有什么访问权限（角色）。 您可以使用 IAM 政策向用户授予特定角色，从而给予用户特定权限。

本页面介绍适用于 Cloud Billing API 的 Identity and Access Management 角色。例如，您可以使用 IAM 为 Cloud Billing 账号授予 Admin、User 和 Project Manager 等角色。如需详细了解 IAM 及其功能，请参阅 Identity and Access Management 开发者指南，请特别留意授予、更改和撤消访问权限部分。

权限和角色

要让用户在 Google Cloud 控制台中查看 Cloud Billing 账号详细信息，或者使 Cloud Billing API 方法返回 Cloud Billing 账号信息，用户或调用方必须拥有必要的权限。下表列出了使用 Cloud Billing Budget API 所需的 IAM 权限和角色。

Cloud Billing Budget API 所需的权限

下表概括了调用每个 Cloud Billing Budget API 方法所需的权限，还包括可自动授予这些权限的标准 IAM Billing 角色。

API 方法	所需权限	可授予权限的 IAM 角色
GetBudget	如需获取预算的详细信息，调用方必须对预算的 Cloud Billing 账号拥有 billing.budgets.get 权限。 对于单项目预算，调用者可以对项目具有以下权限（而不是结算账号权限）：resourcemanager.projects.get 和 billing.resourcebudgets.read。	预算的 Cloud Billing 账号的 Billing Account Administrator、Billing Account Costs Manager 或 Billing Account Viewer。 对于单个项目的预算：项目的 Project Owner、Project Editor 或 Project Viewer。
ListBudgets	如需返回应用到 Cloud Billing 账号的预算列表，调用者必须对 Cloud Billing 账号拥有 billing.budgets.list 权限。 对于单项目预算，调用者可以对项目具有以下权限（而不是结算账号权限）：resourcemanager.projects.get 和 billing.resourcebudgets.read。	预算的 Cloud Billing 账号的 Billing Account Administrator、Billing Account Costs Manager 或 Billing Account Viewer。 对于单个项目的预算：项目的 Project Owner、Project Editor 或 Project Viewer。
CreateBudget	如需创建新预算，调用方必须对预算的 Cloud Billing 账号拥有 billing.budgets.create 权限。 对于单项目预算，调用者可以对项目具有以下权限（而不是结算账号权限）：resourcemanager.projects.get、billing.resourcebudgets.read 和 billing.resourcebudgets.write。	预算的 Cloud Billing 账号的 Billing Account Administrator 或 Billing Account Costs Manager。 对于单个项目的预算：项目的 Project Owner 或 Project Editor。
UpdateBudget	如需更新现有预算，调用方必须对预算的 Cloud Billing 账号拥有 billing.budgets.update 权限。 对于单项目预算，调用者可以对项目具有以下权限（而不是结算账号权限）：resourcemanager.projects.get、billing.resourcebudgets.read 和 billing.resourcebudgets.write。	预算的 Cloud Billing 账号的 Billing Account Administrator 或 Billing Account Costs Manager。 对于单个项目的预算：项目的 Project Owner 或 Project Editor。
DeleteBudget	如需删除现有预算，调用方必须对预算的 Cloud Billing 账号拥有 billing.budgets.delete 权限。 对于单项目预算，调用者可以对项目具有以下权限（而不是结算账号权限）：resourcemanager.projects.get、billing.resourcebudgets.read 和 billing.resourcebudgets.write。	预算的 Cloud Billing 账号的 Billing Account Administrator 或 Billing Account Costs Manager。 对于单个项目的预算：项目的 Project Owner 或 Project Editor。

角色

您不直接授予用户权限，而是向其授予角色（角色自带一个或多个权限）。

您可以针对同一项资源授予一个或多个角色。

下表列出了您可以为访问 Cloud Billing API 而授予的标准 IAM Billing 角色、角色的作用说明以及该角色提供的权限。

如需向 Cloud Billing API 授予权限，请为 API 设置服务账号，并将角色分配给服务账号。
