webmvc的Gateway这种非阻塞式的网关是基于webflux的对于集成Security相关内容略有不同且涉及到代理其它微服务所以会稍微比较麻烦些今天就带大家来实现Gateway网关对接OAuth2认证服务。 Gateway对接说明 身份问题 在本次示例中网关既是客户端(OAuth2 Client Server)又是资源服务(OAuth2 Resource Server)Client服务负责认证Resource负责鉴权这样如果有在浏览器直接访问网关的需要可以直接在浏览器由框架引导完成OAuth2认证过程。 框架版本与架构说明 架构图 Spring Cloud依赖版本 框架版本号Spring Boot3.1.0Nacos Server2.2.1Spring Cloud2022.0.4Spring Cloud Alibaba2022.0.0.0Spring Security6.1.0Spring OAuth2 Client6.1.0Spring OAuth2 Resource Server6.1.0 读者可以自选版本使用作为对接方版本问题不大不确定Spring Cloud Alibaba 在部署时会不会有Spring Boot的版本限制如果3.1.x无法使用请降级至3.0.10版本开发时测试都是没问题的。 网关集成认证服务请求流程图说明 用户请求受限资源网关检测没有认证信息通过RedirectServerAuthenticationEntryPoint处理并发起OAuth2登录授权申请授权申请到达认证服务认证服务检测到未登录重定向至登录页面并展示给用户用户登录成功后请求重定向至授权申请接口通过校验后携带Token重定向至回调地址(redirect_uri)注意这里回调地址要设置为网关的地址htttp://{网关ip}:{网关port}/login/oauth2/code/{registrationId}后边的/login/oauth2/code/{registrationId}路径是固定的这是框架(Security OAuth2 Client)自带的端点请求到达网关由OAuth2LoginAuthenticationWebFilter拦截并调用父类AuthenticationWebFilter的filter方法进行处理AuthenticationWebFilter调用OidcAuthorizationCodeReactiveAuthenticationManager或OAuth2LoginReactiveAuthenticationManager类处理(由授权申请的scope决定包含openid就走OidcAuthorizationCodeReactiveAuthenticationManager否则走另一个)在获取AccessToken成功以后调用ReactiveOAuth2UserService获取用户信息获取到用户信息后会解析并将认证信息保存至ReactiveSecurityContextHolder中完成这一系列的认证之后会重定向至最一开始请求的受限资源这时候就能获取到认证信息了如果访问的是被网关代理的服务则会通过令牌中继(TokenRelay)携带token访问 这就是网关通过认证服务获取认证信息的一个流程基本上只需要添加配置文件即可由框架引导进行OAuth2认证流程。 开始编码 前置条件 搭建好标准OAuth2认证服务搭建nacos服务 项目结构 gateway-example # 父模块│ ├─gateway-client-example # 网关│ ├─normal-resource-example # webmvc资源服务│

在postman中直接访问网关接口或代理的服务接口 被重定向至登录了携带X-Requested-With请求头访问代表当前是xhr请求 响应401框架有区分是浏览器请求还是xhr请求对于浏览器请求会重定向到页面对于xhr请求默认会响应401状态码可自己实现异常处理这里错误信息在请求头中是因为没有重写异常处理网关资源服务配置代码中有注释。 在浏览器中访问网关接口或代理的服务接口 访问 浏览器打开地址http://127.0.0.1:7000/resource/app 请求到达网关后检测到未登录会引导用户进行OAuth2认证流程 登录后提交 登录提交后认证服务重定向授权申请接口校验通过后会生成code并携带code重定向至回调地址注意这里的回调地址是网关的服务地址由网关中的OAuth2 Client处理如图 网关会根据code换取token获取token后根据token获取用户信息并调用网关客户端配置中自定义的userAuthoritiesMapper解析权限信息。 访问权限不足的接口 响应403并将错误信息放入响应头中 使用token访问网关 过期token 响应401并在响应头中提示token已过期 错误token 响应401并在响应头中提示token无法解析 权限不足token 响应403并提示权限不足 正常请求 响应200并正确响应接口信息 写在最后 本文带大家简单实现了Spring Cloud Gateway对接认证服务Gateway中添加客户端主要是为了如果代理服务有静态资源(html、css、image)时可以直接发起OAuth2授权流程在浏览器登录后直接访问同时也是开启令牌中继的必要依赖引入Resource Server依赖是当需要对网关的接口鉴权时可以直接使用如果网关只负责转发应该是可以去掉资源服务相关依赖和配置的由各个被代理的微服务对自己的接口进行鉴权。这些东西在之前基本都是讲过的内容所以本文很多地方都是一笔带过的如果某些地方不清楚可以针对性的翻翻之前的文章也可以在评论区中提出。 如果有什么问题或者需要补充的请在评论区指出谢谢。 附录 Gitee仓库地址 Gateway令牌中继文档
