springboot后端如何实现携带token登陆

时间:2022-11-19 nian002 人气:0

实现思路

使用oauth2+redis+mysql来完成登陆校验，本案例使用oauth2简单的密码模式来实现。

最终实现的效果为

登陆页面不设置权限审核，用户通过登陆界面登陆，输入账户密码，后端接收到账户密码之后会去数据库验证，如果验证通过，则返回token给前端。
除了登陆页面之外，其余的页面访问的时候会进行权限的鉴定，如果携带的token对应用户的权限不足或没有携带token、携带了错误的token，不允许访问。
token具有时限，超时token会失效，可以通过refresh_token来刷新token的持续时间。

项目结构

项目的结构为

├─.idea
│  └─dictionaries
├─log
├─src
│  ├─main
│  │  ├─java
│  │  │  └─Rush
│  │  │      ├─config
│  │  │      ├─controller
│  │  │      ├─mapper
│  │  │      ├─pojo
│  │  │      ├─service
│  │  │      └─util
│  │  └─resource
│  └─test
│
└─target

项目的重点其实也就在于config包内

config包内定义了4个类：

AuthorizationServerConfig
ResourceServerConfig
WebSecurityConfig
CORSFilter「额外针对OAuth跨域问题」

除此之外，继承了UserDetails接口的User类，继承UserDetailsService类的UserService类也很关键。

除了这6个类之外，别的类和普通mybatis项目无异

对于接口的传参数

获取token

使用POST方法

http://localhost:8080/oauth/token?username=sang&password=123&grant_type=password&client_id=password&scope=all&client_secret=123

刷新token

使用POST方法

http://localhost:8080/oauth/token?grant_type=refresh_token&refresh_token=1a1c67a0-5f9b-49b1-9f95-dc7889c85cf5&client_id=password&client_secret=123

携带token访问资源

在url内直接携带token

GET方法

http://localhost:8080/user/hello?access_token=9bdde947-19b7-46fe-8fe0-0f2804150768

在header内携带token

GET方法

http://localhost:8080/admin/hello
------------Header----------------
Authorization ： bearer 3929d92d-f5be-4b2d-9223-8b13e2412f14
Accept ： application/json
