基于JWT实现SSO单点登录1

single sign on(SSO) 的效果是什么?

202306181908034601.png

如上图:

  1. 用户在应用a触发了登录,那么a会拿到一个jwt信息
  2. 用户在应用b不用登录,会发现已经登录过了?然后返回一个jwt给应用b。完成应用b的登录

这里没有搞明白是怎么控制的、后面再来完善

创建项目结构

不在之前的项目上继续了,之前的项目用于讲解浏览器和app不同的支持;

这次的是既支持浏览器跳转也支持json返回这种。

编写的代码比较简单。从零开始搭建sso需要做些什么。更容易理解;

如果自己有任何需求,可以自定义的去实现合并某些功能

项目结构:分别对应上图的4个角色;

    sso-client1
    sso-client2
    sso-demo
    sso-server

4个都是gradle的模块

    rootProject.name = 'spring-security'
    include 'security-app'
    include 'security-browser'
    include 'security-core'
    include 'security-demo'
    include 'sso-client1'
    include 'sso-client2'
    include 'sso-demo'
    include 'sso-server'

认证服务器的搭建

sso-server/build.gradle

    dependencies {
        compile('org.springframework.boot:spring-boot-starter-security')
        compile('org.springframework.boot:spring-boot-starter-web')
        compile 'org.springframework.security.oauth:spring-security-oauth2'
        compile 'org.springframework.security:spring-security-jwt'
        testCompile('org.springframework.boot:spring-boot-starter-test')
        testCompile('org.springframework.security:spring-security-test')
    }

对比下面的配置:

这里的配置与之前的core中的配置最大的区别是,没有引入 org.springframework.security.oauth.boot:spring-security-oauth2-autoconfigure:2.0.0.RELEASE
可以是因为这个原因,才不需要设置authenticationManager吧?

    
    package cn.mrcode.imooc.springsecurity.sso.ssoserver;
    
    @Configuration
    @EnableAuthorizationServer
    public class SsoAuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
    
        @Override
        public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
            clients.inMemory()
                    .withClient("myid1")
                    .secret("myid1")
                    .authorizedGrantTypes("authorization_code", "refresh_token")
                    .scopes("all")
                    .redirectUris(
                            "http://example.com",
                            "http://ora.com")
                    .and()
                    .withClient("myid2")
                    .secret("myid2")
                    .authorizedGrantTypes("authorization_code", "refresh_token")
                    .scopes("all");
        }
    
        @Override
        public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
            endpoints.tokenStore(jwtTokenStore()).accessTokenConverter(jwtAccessTokenConverter());
        }
    
        @Override
        public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
            // 客户端来向认证服务器获取签名的时候需要登录认证身份才能获取
            // 因为客户端需要用密钥解密jwt字符串
            security.tokenKeyAccess("isAuthenticated()");
        }
    
        @Bean
        public TokenStore jwtTokenStore() {
            return new JwtTokenStore(jwtAccessTokenConverter());
        }
    
        @Bean
        public JwtAccessTokenConverter jwtAccessTokenConverter() {
            JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
            converter.setSigningKey("imooc");
            return converter;
        }
    }

注意改成默认的basic;

    package cn.mrcode.imooc.springsecurity.sso.ssoserver;
    
    import org.springframework.context.annotation.Configuration;
    import org.springframework.security.config.annotation.web.builders.HttpSecurity;
    import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
    
    @Configuration
    public class MyWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.httpBasic();
        }
    }

sso-server application.yml

    server:
      port: 9999
      servlet:
        context-path: /server
    
    spring:
      security:
        user:
          password: 123456

启动项目,一切正常;

浏览器访问以下地址获取code;发现连授权页面都和以前的不一样了。我有点费解

    http://localhost:9999/server/oauth/authorize?response_type=code&client_id=myid1&redirect_uri=http://www.example.com&scope=all
