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
4.0.0io.spring2goauthcode-server0.0.1-SNAPSHOTjarauthcode-serverDemo project for Spring Bootorg.springframework.bootspring-boot-starter-parent1.5.10.RELEASEUTF-8UTF-81.8org.springframework.bootspring-boot-starter-securityorg.springframework.bootspring-boot-starter-web org.springframework.security.oauthspring-security-oauth2org.springframework.bootspring-boot-starter-testtestorg.springframework.securityspring-security-testtestorg.springframework.bootspring-boot-maven-plugin
2 修改application.properties设置用户登录密码
# Spring Security =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_userinfoclients.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 ResponseEntitygetUserInfo() {
String user = (String) SecurityContextHolder.getContext()
.getAuthentication().getPrincipal();
String email = user+ "@";
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。
