使用SpringSecurity 实现 OAuth2 资源服务器认证服务器分离（注册码模式）

要解决的问题：不暴露客户密码的情况下授权三方服务访问客户资源

角色：资源拥有者，客户端应用（三方服务），授权服务器，资源服务器

模式：授权码模式：需要客户授权得到授权码后再次通过三方服务的密码取得token，双重校验，最安全，最复杂

简易模式：无需授权码对用户暴露返回的Token，不安全

密码模式：客户端应用需要资源拥有者密码。全链路可信情况下使用

客户端模式：无需资源拥有者密码，只需要客户端应用密码进行校验，服务器对服务器使用

本试验主要演示注册码模式，分为授权服务器和资源服务器俩个应用，后续会持续扩展为单个授权服务器和多个资源服务器。

试验步骤

按照以下截图创建授权服务器，授权服务器包结构如下

1 使用pom文件导入相应依赖，主要导入了以下依赖包

1）SpringBoot的security和web，

2）SpringSecurity的OAuth2

pom文件如下

            </plugin>
        </plugins>
    </build>


</project>

2 修改application.properties设置用户登录密码

# Spring Security Setting
security.user.name=bobo
security.user.password=xyz

3 制作SpringBoot的启动文件

package com.test.authcodeserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class AuthCodeServerApplication {
    public static void main(String[] args) {
        SpringApplication.run(AuthCodeServerApplication.class, args);
    }
}

4 设置授权服务代码

package com.test.authcodeserver.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.security.oauth2.config.annotation.configurers.ClientDetailsServiceConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configuration.AuthorizationServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableAuthorizationServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerEndpointsConfigurer;
import org.springframework.security.oauth2.config.annotation.web.configurers.AuthorizationServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.token.DefaultTokenServices;
import org.springframework.security.oauth2.provider.token.TokenStore;
import org.springframework.security.oauth2.provider.token.store.InMemoryTokenStore;
import org.springframework.security.oauth2.provider.token.store.JdbcTokenStore;

@Configuration
@EnableAuthorizationServer
public class AuthCodeServerConfig extends AuthorizationServerConfigurerAdapter {
@Override
    public void configure(final AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()");
    }
    @Override
    public void configure(ClientDetailsServiceConfigurer clients)
            throws Exception {
        //JdbcClientDetailsService可以动态管理数据库中客户端数据
        //http://localhost:8080/oauth/authorize?client_id=testclientid&redirect_uri=http://localhost:9001/authCodeCallback&response_type=code&scope=read_userinfo
clients.inMemory()
                .withClient("testclientid")//clientId：（必须的）用来标识客户的Id。
.secret("1234")//secret：（需要值得信任的客户端）客户端安全码，如果有的话。
.redirectUris("http://localhost:9001/authCodeCallback")//客户端应用负责获取授权码的endpoint
.authorizedGrantTypes("authorization_code")// 授权码模式
.scopes("read_userinfo", "read_contacts");//scope：用来限制客户端的访问范围，如果为空（默认）的话，那么客户端拥有全部的访问范围。
}

}

5 启动SpringBoot服务

6 客户端服务访问授权服务器，铜鼓访问如下url取得授权码

http://localhost:8080/oauth/authorize?client_id=testclientid&redirect_uri=http://localhost:9001/authCodeCallback&response_type=code&scope=read_userinfo

访问完成后会redirect回客户端服务器并将授权码作为参数传回，其中localhost：9001即为客户端应用

7 客户端使用返回的授权码获取访问令牌

发送请求参数如下

url：http://localhost:8080/oauth/token

code=ifz2BV&grant_type=authorization_code&redirect_uri=http%3A%2F%2Flocalhost%3A9001%2FauthCodeCallback&scope=read_userinfo

得到的令牌数据

{

access_token: "554338cd-cab0-4ba0-b5bf-3ebd55db3196"

token_type: "bearer"

expires_in: 43199

scope: "read_userinfo"

}

以上授权服务器就简单完成了，下面将制作资源服务器

--------------------------------------------------------------------------------------------------

资源服务器

0 资源服务器的包结构

1 资源服务器配置，使用RemoteTokenServices调取认证服务器的认证方法来对Token进行认证

package com.test.resourceserver.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.oauth2.common.OAuth2AccessToken;
import org.springframework.security.oauth2.common.exceptions.InvalidTokenException;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configuration.ResourceServerConfigurerAdapter;
import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.token.DefaultTokenServices;
import org.springframework.security.oauth2.provider.token.RemoteTokenServices;
import org.springframework.security.oauth2.provider.token.ResourceServerTokenServices;
import org.springframework.security.web.AuthenticationEntryPoint;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

//资源服务配置
@Configuration
@EnableResourceServer
public class OAuth2ResourceConfig extends ResourceServerConfigurerAdapter {

    @Primary
    @Bean
    public RemoteTokenServices tokenServices() {
        final RemoteTokenServices tokenService = new RemoteTokenServices();
        tokenService.setCheckTokenEndpointUrl("http://localhost:8080/oauth/check_token");
        tokenService.setClientId("testclientid");
        tokenService.setClientSecret("1234");
        return tokenService;
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {

//        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
//                .and()
//                .authorizeRequests()
//                .anyRequest()
//                .authenticated()
//                .and()
//                .requestMatchers()
//                .antMatchers("/api/**");
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
                .and()
                .authorizeRequests().anyRequest().permitAll();
    }
}

2 提供对外的API接口

package com.test.resourceserver.api;

import org.springframework.http.ResponseEntity;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.User;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class UserController {

   // 资源API
@RequestMapping("/api/userinfo")
    public ResponseEntity<UserInfo> getUserInfo() {

        String  user  = (String) SecurityContextHolder.getContext()
                .getAuthentication().getPrincipal();
        String email = user+ "@test.com";
        UserInfo userInfo = new UserInfo();
        userInfo.setName(user);
        userInfo.setEmail(email);
        return ResponseEntity.ok(userInfo);
    }

}

调用getUserInfo

http://localhost:8004/api/userinfo

authorization: Bearer 638aa01c-4ccd-4873-ab86-d46f22aea091

调用后返回资源服务器的结果

至此一个资源服务器和认证服务器分离的资源调用就结束了。
