接入 SAML

安全断言标记语言（英语：Security Assertion Markup Language，简称SAML，发音sam-el）是一个基于XML的开源标准数据格式，它在当事方之间交换身份验证和授权数据，尤其是在身份提供者和服务提供者之间交换。SAML 2.0 可以实现基于网络跨域的单点登录（SSO），以便于减少向一个用户分发多个身份验证令牌的管理开销。

SAML 2.0 协议简介

SAML 主体

在 SAML 协议中，涉及两个主体

Service Provider 服务提供方，简称 SP

Identity Provider 身份提供方，简称 IdP

这两个主体通过用户的浏览器进行信息交换。方式上，比如 SP 可以返回带参数的重定向，让用户立刻将信息发给 IdP。而 IdP 会返回一个表单，同时还有一段立即提交表单的 JS 代码，从而让用户立刻将信息发给 SP。

SAML Request

当用户的身份无法鉴定时，SP 会向 IdP 发送 SAML Request 信息（通过浏览器发送），请求 IdP 来鉴定用户身份。

SAML Response

IdP 收到 SAML Request 后，会弹出登录框对用户身份进行认证，将用户身份以 Assertion 的形式，发送给 SP（通过浏览器发送）。
