Spring Authorization Server 全新授权服务器整合使用

前言

• Spring Authorization Server 是 Spring 团队最新开发适配 OAuth 协议的授权服务器项目，旨在替代原有的 Spring Security OAuth

• 经过半年的开发和孵化，目前已经发布了 0.1.0 版本，初步支持授权码、客户端、刷新、注销等 OAuth 协议

• 本文环境基于 Spring Boot 2.4.2 && authorization-server 0.1.0

Server 搭建

1. maven 依赖

<!--oauth2 server-->
<dependency>
  <groupId>org.springframework.security.experimental</groupId>
  <artifactId>spring-security-oauth2-authorization-server</artifactId>
  <version>0.1.0</version>
</dependency>
<!--security dependency-->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-security</artifactId>
</dependency>

2. 初始化配置

• 由于官方还未提供对应的 Spring Boot Starter 自动化配置，需要自己配置相关的 @Bean
• 本配置基于 Spring Boot 2.4.2 请知悉

@Configuration
@EnableWebSecurity
@Import(OAuth2AuthorizationServerConfiguration.class)
public class AuthServerConfiguration {

	//  定义 spring security 拦击链规则
	@Bean
	SecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {
		http
				.authorizeRequests(authorizeRequests ->
						authorizeRequests.anyRequest().authenticated()
				)
				.formLogin(withDefaults());
		return http.build();
	}

  // 创建默认登录用户 lengleng / 123456
	@Bean
	public UserDetailsService userDetailsService() {
		UserDetails userDetails = User.builder()
				.username("lengleng")
				.password("{noop}123456")
				.authorities("ROLE_USER")
				.build();
		return new InMemoryUserDetailsManager(userDetails);
	}

  // 创建默认的bean 登录客户端,基于 授权码、 刷新令牌的能力
	@Bean
	public RegisteredClientRepository registeredClientRepository() {
		RegisteredClient client = RegisteredClient.withId("pig")
				.clientId("pig")
				.clientSecret("pig")
				.clientAuthenticationMethod(ClientAuthenticationMethod.BASIC)
				.authorizationGrantTypes(authorizationGrantTypes -> {
					authorizationGrantTypes.add(AuthorizationGrantType.AUTHORIZATION_CODE);
					authorizationGrantTypes.add(AuthorizationGrantType.REFRESH_TOKEN);
				})
				.redirectUri("https://pig4cloud.com")
				.build();
		return new InMemoryRegisteredClientRepository(client);
	}


  // 指定token 生成的加解密密钥
	@Bean
	@SneakyThrows
	public JWKSource<SecurityContext> jwkSource() {
		KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
		keyPairGenerator.initialize(2048);
		KeyPair keyPair = keyPairGenerator.generateKeyPair();
		RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
		RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate();

		// @formatter:off
		RSAKey rsaKey= new RSAKey.Builder(publicKey)
				.privateKey(privateKey)
				.keyID(UUID.randomUUID().toString())
				.build();
		JWKSet jwkSet = new JWKSet(rsaKey);
		return (jwkSelector, securityContext) -> jwkSelector.select(jwkSet);
	}
}

测试

授权码认证

curl --location --request GET 'http://localhost:3000/oauth2/authorize?client_id=pig&client_secret=pig&response_type=code&redirect_uri=https://pig4cloud.com'

获取令牌

curl --location --request POST 'http://localhost:3000/oauth2/token' 
--header 'Authorization: Basic cGlnOnBpZw==' 
--header 'Content-Type: application/x-www-form-urlencoded' 
--data-urlencode 'grant_type=authorization_code' 
--data-urlencode 'code={code}' 
--data-urlencode 'redirect_uri=https://pig4cloud.com'

刷新令牌

curl --location --request POST 'http://localhost:3000/oauth2/token' 
--header 'Authorization: Basic cGlnOnBpZw==' 
--header 'Content-Type: application/x-www-form-urlencoded' 
--data-urlencode 'grant_type=refresh_token' 
--data-urlencode 'refresh_token={refresh_token}' 

撤销令牌

• 通过 access_token

curl --location --request POST 'http://localhost:3000/oauth2/revoke' 
--header 'Authorization: Basic cGlnOnBpZw==' 
--header 'Content-Type: application/x-www-form-urlencoded' 
--data-urlencode 'token={access_token}' 
--data-urlencode 'token_type_hint=access_token'

• 通过 refresh_token

curl --location --request POST 'http://localhost:3000/oauth2/revoke' 
--header 'Authorization: Basic cGlnOnBpZw==' 
--header 'Content-Type: application/x-www-form-urlencoded' 
--data-urlencode 'token={refresh_token}' 
--data-urlencode 'token_type_hint=refresh_token'

内容扩展 | Token 个性化

• RegisteredClient 支持个性化 token 设置的入参

RegisteredClient..tokenSettings()

• 默认配置如下， 包括令牌有效期，刷新令牌控制等

	protected static Map<String, Object> defaultSettings() {
		Map<String, Object> settings = new HashMap<>();
		settings.put(ACCESS_TOKEN_TIME_TO_LIVE, Duration.ofMinutes(5));
		settings.put(REUSE_REFRESH_TOKENS, true);
		settings.put(REFRESH_TOKEN_TIME_TO_LIVE, Duration.ofMinutes(60));
		return settings;
	}

• 由于官方暂时未完善相关的文档，所有的端点入参等需要参考 The OAuth 2.0 Authorization Framework
