如何实现SSO单点登陆？
可以使用跨域Cookie实现单点登录。步骤：1、未登录用户访问子站a.com进行登录，自动跳转到统一登录页；2、用户在统一登录页进行登录，成功后显示登录跳转页，然后自动跳转回a.com，单点登录完成；4、用户在访问b.com时无需再次登录。
单点登录
单点登录（SSO - Single Sign On）：对于同一个客户端（例如 Chrome 浏览器），只要登录了一个子站（例如 a.com），则所有子站（b.com、c.com）都认为已经登录。
比如用户在登录淘宝后，跳转到天猫时就已经登录了。
如何实现SSO单点登陆？
方法：使用跨域Cookie实现单点登录
用例步骤
● 未登录用户访问子站 a.com 进行登录，自动跳转到账户中心的统一登录页 account.com/login
● 用户在统一登录页进行登录，登录成功后显示登录跳转页
● 显示登录跳转页后自动跳转回 a.com，单点登录完成
● 用户在访问 b.com 时无需再次登录
实现原理
登录
● 统一登录页登录请求完成后响应为登录跳转页
● 登录跳转页中通知各子站进行登录
<script src='b.com/login?uid=xxxx&token=xxxxx'></script> <script src='c.com/login?uid=xxxx&token=xxxxx'></script>
● 子站收到登录请求后验证 token 是否有效，有效的话在响应中设置 cookie（user_token=xxxx）
token 验证
● 账户中心使用私钥加密 user id，生成 token
● 子站使用公钥解密 token，将得到的 user id 和参数 uid 对比，如果一样就是校验通过
登出
● 用户在某个子站主动登出时跳转到账户中心统一登出页 account.com/logout?uid=xxxx&token=xxxx
● 账户中心验证 token 后进行登出，在登出跳转页中通知各子站进行登出（设置 cookie），类似登录通知
● 子站收到登出请求后验证 token 是否有效，有效的话在响应中设置 cookie（删除 user_token）
关键点
● 浏览器渲染登录跳转页时将执行上面用

Latest best practices for Java JAAS
Feb 23, 2024 pm 10:52 PM
1. JAAS Overview JavaJAAS (JavaAuthenticationandAuthorizationService) is a framework for multi-system single sign-on (SSO) integration, role-based access control (RBAC) and authorization management. JAAS allows applications to protect access to data or resources and define access control mechanisms. 2. The latest best practices of JAAS 1. Use JAAS for authentication JAAS provides two main authentication methods: Token-based authentication: This method uses tokens (for example, username and password) to verify user identity. Certification-based authentication: This method uses certification (for example, a digital certificate) to verify the user's identity. 2
