SAML2 綜述

安全斷言標記語言（英語：Security Assertion Markup Language，簡稱SAML，發音 sam-el）是一個基于 XML 的開源標準數據格式，它在當事方之間交換身份驗證和授權數據，尤其是在身份提供者和服務提供者之間交換。SAML2.0 可以實現基于網絡跨域的單點登錄（SSO），以便于減少向一個用戶分發多個身份驗證令牌的管理開銷。

SAML 主體

在 SAML 協議中，涉及兩個主體：

Service Provider 服務提供方，簡稱 SP。什么是服務提供方？例如：阿里云控制臺、騰訊云控制臺、AWS 控制臺這些都是服務提供方。

Identity Provider 身份提供方，簡稱 IdP。什么是身份提供方？Authing 可以作為身份提供方，身份提供方能夠向 SP 發送身份斷言，所謂身份斷言就是由 Authing 簽發的，可以標識某個人身份的 Token，只不過，在 SAML 協議中，這個 Token 的格式是 XML 形式的。還有一些其他的身份提供方，例如 Okta、SSOCircle、Auth0，他們都可以向 SP 返回身份斷言。

兩個主體通過用戶的瀏覽器進行信息交換。方式上，SP 可以返回帶參數的重定向 HTTP 響應，讓用戶立刻通過參數將信息發給 IdP。而 IdP 會返回一個表單，同時還有一段立即提交表單的 JS 代碼，從而讓用戶立刻將信息發給 SP。

總結一下，SP 提供服務，需要知道用戶的身份，就需要向 IdP 詢問。IdP 知道用戶的身份，當用戶在 IdP 登錄成功，IdP 就將用戶的身份以 SAML 斷言的形式發給 SP。SP 信任 IdP 發來的身份斷言，從而賦予該用戶在 SP 的相關權限。

SAML Request

當用戶的身份無法鑒定時，SP 會向 IdP 發送 SAML Request 信息（通過瀏覽器發送），請求 IdP 來鑒定用戶身份。

由阿里云控制臺發起一次 SAML Request 的形式是這樣的：

GET https://core.authing.cn/v2/api/saml-idp/5e10927e4ecfd464fb4edaf6?SAMLRequest=fZJLT%2BMwFIX3%2FIrI%2B7yct9Wk6kyFQGJERQKL2RnnJnWV2Blfp2L%2BPaGlDLOApaV7vnN0jlfrl3FwjmBQalWS0AuIA0roVqq%2BJI%2FNtZuTdXW1Qj4OdGKb2e7VA%2FyZAa2zQQRjF91PrXAewdRgjlLA48NdSfbWTsh8H2WvpPL4IP%2FOyhN69N9Qfl3fE2e7UKTi9mR9EQhtwOOLz5LAE8o%2FUp9P8qRyZTv5CYRBQTOIQXRtnMbdcwwt71LiXGsj4JSwJB0fEIhzuy0Jp9AXgvaHgwzzPA%2FjfXagbRYlebeP%2BmI5wh1HlEf4J0Oc4Vah5cqWhAY0cIPCpXkTRiwoWJJ5eZH%2BJs7OaKuFHn5IdS5sNoppjhKZ4iMgs4LVm193jHoBez4fIbtpmp27u68b4jxdiqdvxS9TKGTnqr9nTe%2FGpDovw06JzWfC9wB%2B2Y5UXy8VRlmcpkWUpUlGY5p8TLfyP7tW78%2F%2Fv0f1Cg%3D%3D

SAMLRequest 參數通過 query 在 URL 中發送給 IdP，SAMLRequest 的內容如下：

SAML Response

IdP 收到 SAML Request 后，會彈出登錄框對用戶身份進行認證：

當用戶在 IdP 完成登錄后，SAML IdP 將用戶身份斷言發送給 SP（放在表單中，通過瀏覽器 POST 請求發送）。SAML IdP 的響應內容如下：

(提示：代碼可向右滑動)

這段內容就是用戶的身份斷言，也就是用戶的 Token，只不過這個 Token 通過 XML 格式傳遞。

讀到這里，你可能會對 SP、IdP 如何處理這些冗長的 XML 信息感到困惑。Authing 會解決這些繁瑣的處理，而你只需關注如何正確地配置 Authing IdP，與 SAML SP 進行通信。

SAML2 流程

本文為讀者講述 SAML 中，SP、IdP、瀏覽器三個實體之間數據交互的流程。

SAML 協議中涉及到的主體

使用 SAML 協議進行身份認證時，涉及到以下三個主體

瀏覽器：SP 和 IdP 借助瀏覽器互相通信SP：資源提供方IdP：身份認證提供方

發起 SAML 登錄到登錄成功的整個過程

用戶試圖登錄 SP 提供的應用。SP 生成 SAML Request，通過瀏覽器重定向，向 IdP 發送 SAML Request。IdP 解析 SAML Request 并將用戶重定向到認證頁面。用戶在認證頁面完成登錄。IdP 生成 SAML Response，通過對瀏覽器重定向，向 SP 的 ACS 地址返回 SAML Response，其中包含 SAML Assertion 用于確定用戶身份。SP 對 SAML Response 的內容進行檢驗。用戶成功登錄到 SP 提供的應用。

SP 與 IdP 之間通信方式

SP 與 IdP 之間的通信方式分為 HTTP Redirect Binding、HTTP POST Binding、HTTP Artifact Binding。每種方式在不同的階段會用不同類型的 HTTP 與對方通信。

HTTP Redirect Binding

SP 通過重定向 GET 請求把 SAML Request 發送到 IdP，IdP 通過立即提交的 Form 表單以 POST 請求的方式將 SAML Response 發到 SP。
