【springsecurity oauth2授权中心】jwt令牌更换成自省令牌 OpaqueToken P4

前言

前面实现了授权中心授权，客户端拿到access_token后就能请求资源服务器接口

权限的校验都是在资源服务器上进行的，授权服务器颁发的access_token有限期是2小时，也就是说在2小时之内，不管授权服务器那边用户的权限如何变更都不会影响到资源服务器上的资源请求。

这篇来解决这个问题，让客户端对资源服务器的每次请求都要去问问授权服务器access_token是否还有效，有效的话资源服务器才能通过

授权服务器

在 application.yml 里的 grant-types 后面添加一个 client_credentials

# 之前
oauth2:client:#...grant-types: authorization_code,refresh_token# 修改后
oauth2:client:#...grant-types: authorization_code,refresh_token,client_credentials

配置类 AuthorizationServerConfig 里将 OAuth2TokenCustomizer 由 JwtEncodingContext 改成 OAuth2TokenClaimsContext

//之前//    @Bean
//    public OAuth2TokenCustomizer<JwtEncodingContext> jwtCustomizer() {
//        return context -> {
//            if (context.getTokenType().getValue().equals("access_token")) {
//                Collection<? extends GrantedAuthority> authorities = context.getPrincipal().getAuthorities();
//                List<String> authorityNames = authorities.stream()
//                        .map(GrantedAuthority::getAuthority)
//                        .collect(Collectors.toList());
//                context.getClaims().claim("authorities", authorityNames);
//            }
//        };
//    }//修改后
@Beanpublic OAuth2TokenCustomizer<OAuth2TokenClaimsContext> tokenCustomizer() {return context -> {if (context.getTokenType().getValue().equals("access_token")) {// 从用户详情中提取权限Collection<? extends GrantedAuthority> authorities =context.getPrincipal().getAuthorities();// 将权限列表放入令牌声明context.getClaims().claim("authorities",authorities.stream().map(GrantedAuthority::getAuthority).collect(Collectors.toList()));}};}

资源服务器

添加一个依赖

<dependency><groupId>com.nimbusds</groupId><artifactId>oauth2-oidc-sdk</artifactId><version>11.23.1</version><scope>runtime</scope></dependency>

创建一个自省令牌解析器 CustomAuthoritiesOpaqueTokenIntrospector

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.oauth2.core.DefaultOAuth2AuthenticatedPrincipal;
import org.springframework.security.oauth2.core.OAuth2AuthenticatedPrincipal;
import org.springframework.security.oauth2.server.resource.introspection.OpaqueTokenIntrospector;import java.util.Collection;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;public class CustomAuthoritiesOpaqueTokenIntrospector implements OpaqueTokenIntrospector {private final OpaqueTokenIntrospector delegate;public CustomAuthoritiesOpaqueTokenIntrospector(OpaqueTokenIntrospector delegate) {this.delegate = delegate;}@Overridepublic OAuth2AuthenticatedPrincipal introspect(String token) {OAuth2AuthenticatedPrincipal principal = this.delegate.introspect(token);Map<String, Object> claims = principal.getAttributes();List<String> authorities = (List<String>) claims.get("authorities");if (authorities == null) throw new SecurityException("没有权限");Collection<GrantedAuthority> grantedAuthorities = authorities.stream().map(auth -> new SimpleGrantedAuthority(auth)) // 直接使用权限名，不加 SCOPE_ 前缀.collect(Collectors.toList());return new DefaultOAuth2AuthenticatedPrincipal(claims, grantedAuthorities);}
}

修改 ResourceServerConfig 配置类

    @Beanpublic SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {http.authorizeHttpRequests(authorize -> authorize.anyRequest().authenticated()).oauth2ResourceServer(oauth2 -> oauth2// 注释掉jwt
//                        .jwt(jwt -> jwt
//                                .jwkSetUri("http://localhost:9000/oauth2/jwks")
//                                .jwtAuthenticationConverter(jwtAuthenticationConverter()) // 使用自定义转换器
//                        )// 添加上 opaque.opaqueToken(opaque -> opaque
//                                        .introspectionUri("http://localhost:9000/oauth2/introspect")
//                                        .introspectionClientCredentials("client", "secret").introspector(customOpaqueTokenIntrospector())));return http.build();}// jwt权限转换器，这里用不到了注释掉
//    @Bean
//    public JwtAuthenticationConverter jwtAuthenticationConverter() {
//        JwtGrantedAuthoritiesConverter grantedAuthoritiesConverter = new JwtGrantedAuthoritiesConverter();
//        grantedAuthoritiesConverter.setAuthoritiesClaimName("authorities"); // 指定JWT中权限字段名
//        grantedAuthoritiesConverter.setAuthorityPrefix(""); // 去掉默认的"SCOPE_"前缀
//
//        JwtAuthenticationConverter jwtAuthenticationConverter = new JwtAuthenticationConverter();
//        jwtAuthenticationConverter.setJwtGrantedAuthoritiesConverter(grantedAuthoritiesConverter);
//        return jwtAuthenticationConverter;
//    }

配置授权服务器的请求 /oauth2/introspect 是内置的，不要修改

    @Beanpublic OpaqueTokenIntrospector customOpaqueTokenIntrospector() {// 1. 创建默认的 Introspector（连接授权服务器）OpaqueTokenIntrospector delegate = new NimbusOpaqueTokenIntrospector("http://localhost:9000/oauth2/introspect","client", // client_id"secret"  // client_secret 与授权服务器保持一致);// 2. 包装成自定义实现return new CustomAuthoritiesOpaqueTokenIntrospector(delegate);}
