OAuth是一个关于授权的开放网络标准,在全世界得到的广泛的应用,目前是2.0的版本。OAuth2在“客户端”与“服务提供商”之间,设置了一个授权层(authorization layer)。“客户端”不能直接登录“服务提供商”,只能登录授权层,以此将用户与客户端分离。“客户端”登录需要OAuth提供的令牌,否则将提示认证失败而导致客户端无法访问服务。OAuth2.0是OAuth协议的延续版本,但不向后兼容OAuth 1.0即完全废止了OAuth1.0。
OAuth2为我们提供了四种授权方式:
1、授权码模式(authorization code)
2、简化模式(implicit)
3、密码模式(resource owner password credentials)
4、客户端模式(client credentials)
授权码模式
授权码相对其他三种来说是功能比较完整、流程最安全严谨的授权方式,通过客户端的后台服务器与服务提供商的认证服务器交互来完成。流程如下图所示:
简化模式
这种模式不通过服务器端程序来完成,直接由浏览器发送请求获取令牌,令牌是完全暴露在浏览器中的,这种模式极力不推崇。流程如下图所示:
密码模式
密码模式也是比较常用到的一种,客户端向授权服务器提供用户名、密码然后得到授权令牌。这种模式不过有种弊端,我们的客户端需要存储用户输入的密码,但是对于用户来说信任度不高的平台是不可能让他们输入密码的。流程如下图所示:
客户端模式
客户端模式是客户端以自己的名义去授权服务器申请授权令牌,并不是完全意义上的授权。如下图所示:
上述简单的介绍了OAuth2内部的四种授权方式,我们下面使用密码模式来进行测试;我们就来讲解下SpringBoot项目中是如何配置使用OAuth2服务器端,并且我们使用数据库中的用户数据来做验证处理,并让OAuth2整合SpringSecurity来保护我们的REST接口。
Oauth2相关的5张表:
- oauth_access_token:访问令牌
- oauth_refresh_token:更新令牌
- oauth_client_details:客户端信息
- oauth_code:授权码
- oauth_approvals:授权记录
- oauth_client_token: 客户端用来记录token信息
只以密码模式来进行测试,不考虑管理功能,只用到了了oauth_client_details,oauth_access_token,oauth_refresh_token 三张表

初始化数据
- 定义了3个角色3个账号
- 以“project_api” 命名resourceServer中的api请求路径,我们定义一个客户端叫做:user-client(认证权限类型:read,write)
- 密码都是user,数据库中存的是加密过后的字符串
INSERT INTO authority VALUES(1,'ROLE_OAUTH_ADMIN'); INSERT INTO authority VALUES(2,'ROLE_RESOURCE_ADMIN'); INSERT INTO authority VALUES(3,'ROLE_PROJECT_ADMIN'); INSERT INTO credentials VALUES(1,b'1','oauth_admin','$2a$10$BurTWIy5NTF9GJJH4magz.9Bd4bBurWYG8tmXxeQh1vs7r/wnCFG2','0'); INSERT INTO credentials VALUES(2,b'1','resource_admin','$2a$10$BurTWIy5NTF9GJJH4magz.9Bd4bBurWYG8tmXxeQh1vs7r/wnCFG2','0'); INSERT INTO credentials VALUES(3,b'1','project_admin','$2a$10$BurTWIy5NTF9GJJH4magz.9Bd4bBurWYG8tmXxeQh1vs7r/wnCFG2','0'); INSERT INTO credentials_authorities VALUE (1,1); INSERT INTO credentials_authorities VALUE (2,2); INSERT INTO credentials_authorities VALUE (3,3); INSERT INTO oauth_client_details VALUES('user_client','project_api', '$2a$10$BurTWIy5NTF9GJJH4magz.9Bd4bBurWYG8tmXxeQh1vs7r/wnCFG2', 'read,write', 'password,refresh_token', 'http://127.0.0.1', 'ROLE_PROJECT_ADMIN', 7200, 1800, NULL, 'true');
创建父工程oauth2,继续建立两个子模块:
- Authorization Server - 授权服务器
- Resource Server - 资源服务器
具体配置下载工程源码查看
(四)Authorization Server - Spring Security配置
创建一个spring security 配置类,在配置类中注入了上面我们自定义的自定义UserDetailsService以及用户密码验证器。
package com.oauth2.authorization.config;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.security.authentication.AuthenticationManager;import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;import org.springframework.security.crypto.password.PasswordEncoder;/** * spring security 配置类 */@Configuration@EnableWebSecurity@EnableGlobalMethodSecurity(prePostEnabled = true) //开启security注解public class WebSecurityConfig extends WebSecurityConfigurerAdapter { /** * 密码编码验证器 * @return */ @Bean public PasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder(); } /** * 自定义UserDetailsService用来从数据库中根据用户名查询用户信息以及角色信息 */ @Autowired public UserDetailsService userDetailsService; @Override @Bean public AuthenticationManager authenticationManagerBean() throws Exception { return super.authenticationManagerBean(); } @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userDetailsService) .passwordEncoder(passwordEncoder()); } /** * 验证配置 * @param http * @throws Exception */ @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests() .antMatchers("/**").authenticated() .and() .userDetailsService(userDetailsService); }}
自定义UserDetailsService
创建一个名叫JdbcUserDetails的类实现UserDetailsService接口,代码如下:
public class JdbcUserDetails implements UserDetailsService { @Autowired private CredentialsDao credentialsDao; @Override public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException { Credentials credentials = credentialsDao.findByName(username); if (credentials == null) { throw new UsernameNotFoundException("User '" + username + "' can not be found"); } return new User(credentials.getName(), credentials.getPassword(), credentials.isEnabled(), true, true, true, credentials.getGrantedAuthorities()); } }
(五)Authorization Server - 授权服务器
授权服务器负责验证用户标识并提供令牌,使用@EnableAuthorizationServer注解启用授权服务器配置。
package com.oauth2.authorization.config;import com.oauth2.authorization.userdetails.JdbcUserDetails;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.security.authentication.AuthenticationManager;import org.springframework.security.core.userdetails.UserDetailsService;import org.springframework.security.crypto.password.PasswordEncoder;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.approval.ApprovalStore;import org.springframework.security.oauth2.provider.approval.JdbcApprovalStore;import org.springframework.security.oauth2.provider.client.JdbcClientDetailsService;import org.springframework.security.oauth2.provider.code.AuthorizationCodeServices;import org.springframework.security.oauth2.provider.code.JdbcAuthorizationCodeServices;import org.springframework.security.oauth2.provider.token.TokenStore;import org.springframework.security.oauth2.provider.token.store.JdbcTokenStore;import javax.sql.DataSource;/** * 授权服务器配置 */@Configuration@EnableAuthorizationServer //注解开启了验证服务器public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter { @Autowired private DataSource dataSource; @Autowired private PasswordEncoder passwordEncoder; @Autowired private AuthenticationManager authenticationManager; @Bean public JdbcClientDetailsService jdbcClientDetailsService() { return new JdbcClientDetailsService(dataSource); } @Bean public TokenStore tokenStore() { return new JdbcTokenStore(dataSource); } @Autowired public UserDetailsService userDetailsService; /** * 配置 token 节点的安全策略 * @param security * @throws Exception */ @Override public void configure(AuthorizationServerSecurityConfigurer security) throws Exception { security.tokenKeyAccess("permitAll()"); // 获取 token 的策略 security.checkTokenAccess("isAuthenticated()"); } /** * 配置客户端信息 * * @param clients * @throws Exception */ @Override public void configure(ClientDetailsServiceConfigurer clients) throws Exception { clients.withClientDetails(jdbcClientDetailsService()); //设置客户端的配置从数据库中读取,存储在oauth_client_details表 } @Override public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception { endpoints.authenticationManager(authenticationManager) // 开启密码验证,来源于 WebSecurityConfigurerAdapter .userDetailsService(userDetailsService) // 读取验证用户的信息 .tokenStore(tokenStore()); }}
资源服务器,受OAuth2令牌保护的资源
package com.oauth2.resources.config;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;import org.springframework.security.config.annotation.web.builders.HttpSecurity;import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;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.token.TokenStore;import org.springframework.security.oauth2.provider.token.store.JdbcTokenStore;import org.springframework.security.web.authentication.logout.LogoutSuccessHandler;import javax.sql.DataSource;/** * 资源服务器配置 */@Configuration@EnableResourceServer@EnableWebSecurity@EnableGlobalMethodSecurity(prePostEnabled = true)public class ResourcesServerConfig extends ResourceServerConfigurerAdapter { @Autowired private DataSource dataSource;@Bean public BCryptPasswordEncoder passwordEncoder() { return new BCryptPasswordEncoder();} @Autowired private LogoutSuccessHandler logoutSuccessHandler; @Bean public TokenStore tokenStore() { return new JdbcTokenStore(dataSource); } @Override public void configure(ResourceServerSecurityConfigurer resources) throws Exception { resources.resourceId("project_api").stateless(false); resources.tokenStore(tokenStore()); } @Override public void configure(HttpSecurity http) throws Exception { http .logout() .logoutUrl("/logout")//虚拟的登出地址 .logoutSuccessHandler(logoutSuccessHandler)//登出做的操作 .and() .authorizeRequests() .antMatchers("/test/hello").permitAll() .antMatchers("/test/**").authenticated(); }}
我们这里设置了一个LogoutSuccessHandler,他的作用是请求/logout地址时,清空数据库中的accessToken,防止被窃取用于访问,代码如下:
package com.oauth2.resources.config; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.security.core.Authentication; import org.springframework.security.oauth2.common.OAuth2AccessToken; import org.springframework.security.oauth2.provider.token.TokenStore; import org.springframework.security.web.authentication.logout.LogoutSuccessHandler; import org.springframework.stereotype.Component; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; /** * 登出清空accessToken */ @Component public class LogoutSuccessHandlerImpl implements LogoutSuccessHandler { private static String BEARER_AUTHENTICATION = "Bearer"; private static String HEADER_AUTHENTICATION = "authorization"; @Autowired private TokenStore tokenStore; @Override public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException { String auth = httpServletRequest.getHeader(HEADER_AUTHENTICATION); String token = httpServletRequest.getParameter("access_token"); if (auth != null && auth.startsWith(BEARER_AUTHENTICATION)) { token = token.split(" ")[0]; } if (token != null) { OAuth2AccessToken accessToken = tokenStore.readAccessToken(token); if (accessToken != null) { tokenStore.removeAccessToken(accessToken); } } } }
资源服务器测试代码
package com.oauth2.resources.controller; import org.springframework.security.access.prepost.PreAuthorize; import org.springframework.security.core.Authentication; import org.springframework.security.core.context.SecurityContextHolder; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping(value = "/test") public class TestController { @GetMapping("/hello") public String hello(){ return "Hello"; } @GetMapping("/meet") public String meet(){ return "I meet you"; } @GetMapping("/welcome") public String welcome(){ Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); return "Welcome " + authentication.getName(); } @GetMapping("/project") @PreAuthorize("hasRole('ROLE_PROJECT_ADMIN')") //具有此角色 public String project(){ return "This is my project"; } }
在ResourceServerConfig配置中,只有/test/hello不需要授权,其他都需要授权。
1. 直接访问 http://localhost:8081/test/hello ,无需授权,所以正常响应,输出hello字符串。
2. 访问 http://localhost:8081/test/meet
可以看到正如我们预期一样,返回了401错误以及错误信息,下面我们来获取access_token。
3. Spring Security OAuth2默认提供的四个URL:
- /oauth/authorize : 授权AuthorizationEndpoint
- /oauth/token : 令牌TokenEndpoint
- /oauth/check_token : 令牌校验CheckTokenEndpoint
- /oauth/confirm_access : 授权页面WhitelabelApprovalEndpoint
- /oauth/error : 错误页面WhitelabelErrorEndpoint
在获取token之前需要在数据库表oauth_client_details添加对应的数据 ,见上方的初始化数据,初始化了一条客户端配置信息。
4.获得令牌,POST请求 http://localhost:8080/oauth/token?grant_type=password&username=curl_client&password=user
可以看到我们访问的地址,grant_type使用到了password模式,username和password即credentials表中的name和password字段值。
获取access_token需要响应头中添加客户端的授权信息,通过Postman工具的头授权信息即可输出对应的值就可以完成Basic Auth的加密串生成,clientid、secret的值存执表oauth_client_details中对应字段。
成功访问后oauth2给我们返回了几个参数:
- access_token:本地访问获取到的access_token,会自动写入到数据库中。
- token_type:获取到的access_token的授权方式
- refersh_token:刷新token时所用到的授权
- tokenexpires_in:有效期(从获取开始计时,值秒后过期)
- scope:客户端的接口操作权限(read:读,write:写)
3.带上授权服务器返回的access_token发访问 http://localhost:8081/test/meet?access_token=7afa7ff0-2e17-4388-b8c7-47355de57537
成功输出。
5. 访问http://localhost:8081/test/welcome?access_token=7afa7ff0-2e17-4388-b8c7-47355de57537
成功打印出了用户的账号。
6. 访问http://localhost:8081/test/project?access_token=7afa7ff0-2e17-4388-b8c7-47355de57537
成功输出。
从代码上到,project方法使用了PreAuthorize注解,要求用户具有ROLE_PROJECT_ADMIN角色才能访问,如果使用一个不具有ROLE_PROJECT_ADMIN角色的账号的access_token访问,将出现下列403提示access_denied:
7. 访问 http://localhost:8081/logout?access_token=7afa7ff0-2e17-4388-b8c7-47355de57537 ,token将被从数据库中删除
再使用该token将提示invalid_token:
