Spring Security OAuth2 - 如何使用 OAuth2Authentication 对象？

Question

我有提供用户信息的 OAuth2 授权服务器：

public class User implements Serializable, UserDetails {
    private Long userID;
    private String username;
    private String password;
    private String fullName;
    private String email;
    private String avatar;
    private boolean enabled;
    // etc
}

@RestController
@RequestMapping("/api")
public class APIController {

    @RequestMapping("/me")
    public User me(@AuthenticationPrincipal User activeUser) {
        return activeUser;
    }
}

我还实现了 OAuth2 客户端作为单独的 Spring Boot 应用程序。

@Configuration
@EnableOAuth2Sso
public class OAuth2ClientConfig extends WebSecurityConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.logout()
            .and()
            .antMatcher("/**").authorizeRequests()
            .antMatchers("/login").permitAll()
            .anyRequest().authenticated();
    }
}

application.yml

security:
  user:
    password: none
  oauth2:
    client:
      clientId:     acme
      clientSecret: acmepassword
      accessTokenUri:       http://localhost:9080/sso/oauth/token
      userAuthorizationUri: http://localhost:9080/sso/oauth/authorize
    resource:
      userInfoUri:    http://localhost:9080/sso/api/me

用户认证成功：

@Controller
public class MainController {

    @RequestMapping(value = "/")
    public String index(Principal principal) {
        System.out.println(principal);
        // org.springframework.security.oauth2.provider.OAuth2Authentication@c2e723e8: Principal: superadmin; Credentials: [PROTECTED]; Authenticated: true; Details: remoteAddress=<ADDRESS>, sessionId=<SESSION>, tokenType=bearertokenValue=<TOKEN>; Granted Authorities: {userRoleID=1, authority=ROLE_SUPERUSER}
        OAuth2Authentication auth = (OAuth2Authentication) principal;
        System.out.println(auth.getUserAuthentication().getDetails());
        // {userID=1, username=superadmin, password=***, fullName=SuperUser, email=superadmin@example.org, avatar=null, enabled=true ...
        return "index";
    }
}

但我不明白如何在我的应用程序中使用提供的 OAuth2Authentication 对象。几乎没用。

当我尝试使用任何 Thymeleaf 安全标签时

<span sec:authentication="principal.fullName">Username</span>
<span sec:authentication="principal.authorities">Authorities</span>
<span sec:authentication="principal.userAuthentication.details.fullName">Usernames</span>

..出现以下异常：

Error retrieving value for property "property name here" of authentication object of class org.springframework.security.oauth2.provider.OAuth2Authentication

标准 Spring Security 方法 isUserInRole() 也不起作用：

System.out.println(servletRequest.isUserInRole("ROLE_SUPERUSER"));
// false

我应该实现自定义 Thymeleaf 安全方言和 hasRole() 方法吗？或者可能存在更简单的解决方案？

Answer 1

好的，经过大量挖掘，我找到了解决方案。

长话短说：ResourceServerTokenServices.loadAuthentication() 方法应该被覆盖以从 OAuth2 资源服务器响应中提取自定义主体和/或权限。主要逻辑封装在extractAuthentication()方法中。

配置

@Configuration
@EnableOAuth2Sso
public class OAuth2ClientConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private ResourceServerProperties sso;

    @Autowired
    private OAuth2RestOperations restTemplate;

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.logout().and().antMatcher("/**").authorizeRequests().antMatchers("/login").permitAll().anyRequest()
                        .authenticated();
    }

    @Bean
    // very important notice: method name should be exactly "userInfoTokenServices"
    public ResourceServerTokenServices userInfoTokenServices() {
        CustomUserInfoTokenServices serv = new CustomUserInfoTokenServices(sso.getUserInfoUri(), sso.getClientId());
        serv.setTokenType(sso.getTokenType());
        serv.setRestTemplate(restTemplate);
        return serv;
    }
}

服务

public class CustomUserInfoTokenServices implements ResourceServerTokenServices {
    // exactly the same as org.springframework.boot.autoconfigure.security.oauth2.resource.UserInfoTokenServices
    // except extractAuthentication() method
}

PS：

新的 Spring Boot 版本提供了更灵活的 API。请参阅PrincipalExtractor 接口。不幸的是，它仅在 2 周前添加，当前稳定的 1.3.5.RELEASE 版本不支持。

希望对你有帮助

使用ResourceServerTokenServices从access_token获取主体

@Autowired
ResourceServerTokenServices  resourceServerTokenServices;

OAuth2Authentication auth = resourceServerTokenServices.loadAuthentication(tokenId);
String principal = auth.getName();
