1，OAuth2.0简介

OAuth（开发授权）是一个开放标准，允许用户授权第三方应用访问他们存储在另外的服务提供者上的信息，而不需要将用户名和密码提供给第三方应用或分享他们数据的所有内容。
OAuth2.0是OAuth的延续，但他并不兼容OAuth1.0，即它完全废除OAuth1.0。很多大公司如Google，Yahoo，Microsoft等都提供了OAuth认证服务，这些都足以说明OAUTH标准逐渐成为开放资源授权的标准。
微信小程序授权登录同样也是提供OAuth认证服务。详情请看

2，业务场景

某一天你想登录网站CSDN，之前没有在CSDN网站注册过，此时在人家的登陆页面提供了其他登录方式，如下图
在这里插入图片描述

假设我们自己做的网站叫网站B，也在上图中红框部分，如下图
在这里插入图片描述

你恰好之前在我们的B网站上注册过账号，那么现在就可以使用B网站上的账号登录在CSDN上。那么我们在B网站上做这样的一个功能就是使用OAuth2做的。

OAuth2.0包含一下几种角色

1，客户端：本身不存储资源，需要通过资源拥有者的授权去请求资源服务器的资源。
2，资源拥有者：通常为用户，也可以是应用程序，即该资源的拥有者。
3，授权服务器（认证服务器）：用于服务提供商对资源拥有者的身份认证，对访问资源进行授权，认证成功后会给客户端发放令牌（access_token），作为客户端访问资源服务器的凭据。
4，资源服务器：存储资源的服务器
5，客户端标识：client_id
6，客户端密钥：client_secret
为什么要有client_id和client_secret呢？
因为服务提供商不能允许随便一个客户端就接入到它的授权服务器，服务提供商会给准入的接入方一个身份，用于接入时的凭据。

ClientDetailsServiceConfigurer：用来配置客户端详情服务（ClientDetailsService），客户端详情信息在 这里进行初始化，你能够把客户端详情信息写死在这里或者是通过数据库来存储调取详情信息。

AuthorizationServerEndpointsConfigurer：用来配置令牌（token）的访问端点和令牌服务(token services)。

AuthorizationServerSecurityConfigurer：用来配置令牌端点的安全约束

    return "用户基本信息";
}

                          6，测试

在测试之前我们再来梳理一下流程

在这里插入图片描述

1，用户想要登录CSDN，

2，用户在CSDN上选择我们的网站B进行快捷登录（此时我们的网站B已经和CSDN有合作，并且给我们网站B给CSND密钥。和客户端ID）

3，当用户选择后跳转到我们的网站B的第三方授权登录页面，

4，用户输入用户名或密码进行授权登录

5，用户请求携带用户名和密码以及CSDN客户端的ID密钥等信息在我们的网站B上进行登录

6，网关断言后将请求分到授权服务

7，授权服务认证通过后响应授权码到网关

8，网关响应授权码并重定向到CSDN

9，CSDN获取授权码，并携带授权码，再次请求我们的网站B以获取access_token

这里我们为什么要获取access_token?

这是因为你要获取的用户信息接口，需要校验这个请求中是否包含access_token,来判断是否是合法请求，这也是Oauth2协议的一个关键部分。之前的是授权码，仅仅代表用户已经同意CSDN网站从我们的网站B上获取他的一些基本信息。而要获取到用户的信息，还必须要有access_token。

10，网关断言后将请求分到授权服务，

11，授权服务通过后，响应access_token给网关

12，网关将access_token响应给CSDN

13，CSDN携带access_token再次请求我们的网站B

14，网关认证（认证access_token是否合法，是否过期等）后，将请求分发到资源服务器

15，资源服务器将用户信息响应给网关

16，网关将用户信息响应给CSDN，

17，CSDN就可以使用这些基本信息来登录

其中1-4部分用户是可以感知的，其余的用户无法感知。

测试：因为我们的网站还无法提供给CSDN做快捷登录

所以我们的模拟只能从9步开始，使用密码登录模式，使用postman进行测试
