Spring Boot集成oauth2快速入门demo

1.oauth2介绍

1,什么是 OAuth 2?

  • OAuth 是一个开放标准,该标准允许用户让第三方应用访问该用户在某一网站上存储的私密资源(如头像、照片、视频等),而在这个过程中无须将用户名和密码提供给第三方应用。实现这一功能是通过提供一个令牌(token),而不是用户名和密码来访问他们存放在特定服务提供者的数据。
  • 每一个令牌授权一个特定的网站在特定的时段内访问特定的资源。这样,OAuth 让用户可以授权第三方网站灵活地访问存储在另外一些资源服务器的特定信息,而非所有内容。目前主流的 qq,微信等第三方授权登录方式都是基于 OAuth2 实现的。
  • OAuth 2 是 OAuth 协议的下一版本,但不向下兼容 OAuth 1.0。OAuth 2 关注客户端开发者的简易性,同时为 Web 应用、桌面应用、移动设备、起居室设备提供专门的认证流程。
  • 传统的 Web 开发登录认证一般都是基于 Session 的,但是在前后端分离的架构中继续使用 Session 会有许多不便,因为移动端(Android、iOS、微信小程序等)要么不支持Cookie(微信小程序),要么使用非常不便,对于这些问题,使用 OAuth 2 认证都能解决。

2,OAuth 2 角色

OAuth 2 标准中定义了以下几种角色:
  • 资源所有者(Resource Owner):即代表授权客户端访问本身资源信息的用户,客户端访问用户帐户的权限仅限于用户授权的“范围”。
  • 客户端(Client):即代表意图访问受限资源的第三方应用。在访问实现之前,它必须先经过用户者授权,并且获得的授权凭证将进一步由授权服务器进行验证。
  • 授权服务器(Authorization Server):授权服务器用来验证用户提供的信息是否正确,并返回一个令牌给第三方应用。
  • 资源服务器(Resource Server):资源服务器是提供给用户资源的服务器,例如头像、照片、视频等。
注意:一般来说,授权服务器和资源服务器可以是同一台服务器。

2.环境准备

docker run -itd --name redis-6379 -p 6379:6379 redis --requirepass 123456

3.代码工程

实验目的:通过 oauth2办法access_token实现对接口权限的控制

    public String admin() {
        return "hello admin";
    }

    @GetMapping("/user/hello")
    public String user() {

    }

    @GetMapping("/hello")
    public String hello() {
        return "hello";

4.测试

启动Spring boot应用

获取access_token

postman输入http://127.0.0.1:8088/oauth/token获取 4

访问资源(有admin角色)

postman输入http://127.0.0.1:8088/admin/hello?access_token=f57880ae-15d1-49dd-a63a-299827c8d341 0

无权限访问(没有user角色)

postman输入http://127.0.0.1:8088/user/hello?access_token=f57880ae-15d1-49dd-a63a-299827c8d341 1
