Spring Authorization Server 1.1 扩展 OAuth2 密码模式与 Spring Cloud Gateway 整合实战

前言

Spring Security OAuth2 的最终版本是2.5.2，并于2022年6月5日正式宣布停止维护。Spring 官方为此推出了新的替代产品，即 Spring Authorization Server。然而，出于安全考虑，Spring Authorization Server 不再支持密码模式，因为密码模式要求客户端直接处理用户的密码。但对于受信任的第一方系统(自有APP和管理系统等)，许多情况下需要使用密码模式。在这种情况下，需要在 Spring Authorization Server 的基础上扩展密码模式的支持。本文基于开源微服务商城项目 youlai-mall、Spring Boot 3 和 Spring Authorization Server 1.1 版本，演示了如何扩展密码模式，以及如何将其应用于 Spring Cloud 微服务实战。

无图无真相

通过 Spring Cloud Gateway 访问认证中心认证成功获取到访问令牌。完整源码：youlai-mall

创建数据库

Spring Authorization Server 官方提供的授权服务器示例 demo-authorizationserver 初始化数据库所使用的3个SQL脚本路径如下：

根据路径找到3张表的SQL脚本

• 令牌发放记录表: oauth2-authorization-schema.sql
• 授权记录表: oauth2-authorization-consent-schema.sql
• 客户端信息表: oauth2-registered-client-schema.sql

整合后的完整数据库 SQL 脚本如下：

-- ----------------------------
-- 1. 创建数据库
-- ----------------------------
CREATE DATABASE IF NOT EXISTS oauth2_server DEFAULT CHARACTER SET utf8mb4 DEFAULT COLLATE utf8mb4_general_ci;

-- ----------------------------
-- 2. 创建表

授权服务器

youlai-auth 模块作为认证授权服务器

maven 依赖

在 youlai-auth 模块的 pom.xml 添加授权服务器依赖

<dependency>
    <groupId>org.springframework.securitygroupId>
    <artifactId>spring-security-oauth2-authorization-serverartifactId>
    <version>1.1.1version>
dependency>

application.yml

认证中心配置 oauth2_server 数据库连接信息

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver 
    url: jdbc:mysql://localhost:3306/oauth2_server?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&autoReconnect=true
    username: root
    password: 123456

自定义认证响应

如何自定义 OAuth2 认证成功或失败的响应数据结构符合当前系统统一的规范？

下图左侧部份是 OAuth2 原生返回(⬅️ )，大多数情况下，我们希望返回带有业务码的数据(➡️)，以方便前端进行处理。

OAuth2 处理认证成功或失败源码坐标 OAuth2TokenEndpointFilter#doFilterInternal ，如下图：

根据源码阅读，发现只要重写✅ AuthenticationSuccessHandler 和❌ AuthenticationFailureHandler 的逻辑，就能够自定义认证成功和认证失败时的响应数据格式。

认证成功响应

package com.youlai.auth.handler;

/**
 * 认证成功处理器
 *
 * @author haoxr
 * @since 3.0.0
 */
public class MyAuthenticationSuccessHandler implements AuthenticationSuccessHandler {

    /**
     * MappingJackson2HttpMessageConverter 是 Spring 框架提供的一个 HTTP 消息转换器，用于将 HTTP 请求和响应的 JSON 数据与 Java 对象之间进行转换
     */
    private final HttpMessageConverter<Object> accessTokenHttpResponseConverter = new MappingJackson2HttpMessageConverter();
    private Converter<OAuth2AccessTokenResponse, Map<String, Object>> accessTokenResponseParametersConverter = new DefaultOAuth2AccessTokenResponseMapConverter();


    /**
     * 自定义认证成功响应数据结构
     *
     * @param request the request which caused the successful authentication
     * @param response the response
     * @param authentication the Authentication object which was created during
     * the authentication process.
     * @throws IOException
     * @throws ServletException
     */

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException, ServletException {
        OAuth2AccessTokenAuthenticationToken accessTokenAuthentication =
                (OAuth2AccessTokenAuthenticationToken) authentication;

        OAuth2AccessToken accessToken = accessTokenAuthentication.getAccessToken();
        OAuth2RefreshToken refreshToken = accessTokenAuthentication.getRefreshToken();
        Map<String, Object> additionalParameters = accessTokenAuthentication.getAdditionalParameters();

        OAuth2AccessTokenResponse.Builder builder =
                OAuth2AccessTokenResponse.withToken(accessToken.getTokenValue())
                        .tokenType(accessToken.getTokenType());
        if (accessToken.getIssuedAt() != null && accessToken.getExpiresAt() != null) {
            builder.expiresIn(ChronoUnit.SECONDS.between(accessToken.getIssuedAt(), accessToken.getExpiresAt()));
        }
        if (refreshToken != null) {
            builder.refreshToken(refreshToken.getTokenValue());
        }
        if (!CollectionUtils.isEmpty(additionalParameters)) {
            builder.additionalParameters(additionalParameters);
        }
        OAuth2AccessTokenResponse accessTokenResponse = builder.build();

        Map<String, Object> tokenResponseParameters = this.accessTokenResponseParametersConverter
                .convert(accessTokenResponse);
        ServletServerHttpResponse httpResponse = new ServletServerHttpResponse(response);

        this.accessTokenHttpResponseConverter.write(Result.success(tokenResponseParameters), null, httpResponse);
    }
}

认证失败响应

package com.youlai.auth.handler;

/**
 * 认证失败处理器
 *
 * @author haoxr
 * @since 2023/7/6
 */
@Slf4j
public class MyAuthenticationFailureHandler implements AuthenticationFailureHandler {

    /**
     * MappingJackson2HttpMessageConverter 是 Spring 框架提供的一个 HTTP 消息转换器，用于将 HTTP 请求和响应的 JSON 数据与 Java 对象之间进行转换
     */
    private final HttpMessageConverter<Object> accessTokenHttpResponseConverter = new MappingJackson2HttpMessageConverter();


    @Override
    public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {
        OAuth2Error error = ((OAuth2AuthenticationException) exception).getError();
        ServletServerHttpResponse httpResponse = new ServletServerHttpResponse(response);
        Result result = Result.failed(error.getErrorCode());
        accessTokenHttpResponseConverter.write(result, null, httpResponse);
    }
}

配置自定义处理器

AuthorizationServierConfig

public SecurityFilterChain authorizationServerSecurityFilterChain() throws Exception {

    // ...
    authorizationServerConfigurer
        .tokenEndpoint(tokenEndpoint ->
                       tokenEndpoint
                       // ...
                       .accessTokenResponseHandler(new MyAuthenticationSuccessHandler()) // 自定义成功响应
                       .errorResponseHandler(new MyAuthenticationFailureHandler()) // 自定义失败响应
                      );

}

密码模式测试

单元测试

启动 youlai-system 模块，需要从其获取系统用户信息(用户名、密码)进行认证

package com.youlai.auth.authentication;

/**
 * OAuth2 密码模式单元测试
 */
@SpringBootTest
@AutoConfigureMockMvc
@Slf4j
public class PasswordAuthenticationTests {

    @Autowired
    private MockMvc mvc;

    /**
     * 测试密码模式登录
     */
    @Test
    void testPasswordLogin() throws Exception {
        HttpHeaders headers = new HttpHeaders();
        // 客户端ID和密钥
        headers.setBasicAuth("mall-admin", "123456");

        this.mvc.perform(post("/oauth2/token")
                        .param(OAuth2ParameterNames.GRANT_TYPE, "password") // 密码模式
                        .param(OAuth2ParameterNames.USERNAME, "admin") // 用户名
                        .param(OAuth2ParameterNames.PASSWORD, "123456") // 密码
                        .headers(headers))
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.data.access_token").isNotEmpty());
    }
}

单元测试通过，打印响应数据可以看到返回的 access_token 和 refresh_token

Postman 测试

• 请求参数

• 认证参数

  Authorization Type 选择 Basic Auth , 填写客户端ID(mall-admin)和密钥(123456)，

资源服务器

youlai-system 系统管理模块也作为资源服务器

maven 依赖

<dependency>
      <groupId>org.springframework.bootgroupId>
      <artifactId>spring-boot-starter-oauth2-resource-serverartifactId>
dependency>

application.yml

通过 Feign 请求 youlai-system 服务以获取系统用户认证信息（用户名和密码），在用户尚未登录的情况下，需要将此请求的路径配置到白名单中以避免拦截。

security:
  # 允许无需认证的路径列表
  whitelist-paths:
    # 获取系统用户的认证信息用于账号密码判读
    - /api/v1/users/{username}/authInfo

认证流程测试

分别启动 youlai-mall 的 youai-auth (认证中心)、youlai-system(系统管理模块)、youali-gateway(网关)

登录认证授权

• 请求参数

• 认证参数

  Authorization Type 选择 Basic Auth , 填写客户端ID(mall-admin)和密钥(123456)，

• 成功响应

  认证成功，获取到访问令牌(access_token )

  

获取用户信息

使用已获得的访问令牌 (access_token) 向资源服务器发送请求以获取登录用户信息

成功地获取登录用户信息的响应，而不是出现未授权的401错误。

结语

关于 Spring Authorization Server 1.1 版本的密码模式扩展和在 Spring Cloud 中使用新的授权方式，可以说与 Spring Security OAuth2 的代码相似度极高。如果您已经熟悉 Spring Security OAuth2，那么学习 Spring Authorization Server 将变得轻而易举。后续文章会更新其他常见授权模式的扩展，敬请期待~
