由于存在多种访问控制模型和实现方法，为后端服务 API 构建授权系统仍然具有挑战性。最终目标是确保合适的个人能够适当地访问相关资源。本文将探讨如何利用开源 API 网关 Apache APISIX 和开放策略代理（OPA）为 API 实现基于角色的访问控制（RBAC）授权模型。 什么是 RBAC？ 基于角色的访问控制（RBAC）和基于属性的访问控制（ABAC）是两种常用的访问控制模型，用于管理权限和控制对计算机系统资源的访问。RBAC 根据用户在组织中的角色来分配权限。角色是根据用户的职能或职责定义的，权限则分配给这些角色。用户被分配到一个或多个角色，从而继承与这些角色关联的权限。例如，在 API 上下文中，开发人员角色可能具备创建和更新 API 资源的权限，而最终用户角色可能仅具有读取或执行 API 资源的权限。 简而言之，RBAC 根据用户的角色分配权限，而 ABAC 则根据与用户和资源关联的属性分配权限。 在 RBAC 中，策略是由用户分配的角色、他们可以执行的操作以及这些操作可执行的资源的组合来定义的。 什么是 OPA？ OPA（Open Policy Agent）是一个策略引擎和工具集，提供了统一的策略实施方法，适用于整个分布式系统。它允许从一个集中点定义、管理和执行策略。通过将策略定义为代码，OPA 使策略管理更加高效，支持轻松查看、编辑和回滚策略。 OPA 提供了一种名为 Rego 的声明性语言，用于在整个系统中创建和实施策略。当向 OPA 请求策略决策时，它会根据文件中提供的规则和数据来评估查询并生成响应。查询结果作为策略决策返回。OPA 将所有必要的策略和数据存储在内存缓存中，因此能够快速返回结果。以下是一个简单的 OPA Rego 文件示例： package example default allow = falseallow { input.method == “GET” input.path == Read more about 利用 API 网关和开放策略代理 (OPA) 实现 RBAC 管理[…]
