Question

我有一台基于Spring Boot 1.5（Spring Security v4）的Spring OAuth 2服务器，该服务器生成自定义令牌，并有一些与该授权服务器通信的资源服务器，它们通过配置{{ 1}}。与授权服务器端上的令牌存储/检索有关的所有逻辑都是通过/oauth/check_token完成的。

我正在构建一个新的Spring Boot 2应用程序，该应用程序是通过Spring webflux模块构建的，并尝试使用Spring Security 5.1.1使用现有的Authorization Server实现RemoteTokenServices流。我发现在5.1.0.RC1（https://spring.io/blog/2018/08/21/spring-security-5-1-0-rc1-released#oauth2-resource-servers）中添加了对资源服务器的支持，并在5.1.0.RC2（https://spring.io/blog/2018/09/10/spring-security-5-1-0-rc2-released#oauth2-resource-server）中对其进行了更新，但是看起来只能通过JWT支持对其进行配置。

我可能在这里弄乱了概念，但正在寻找更多信息以及一种将所有这些组件一起配置的方法。

我和您的处境相同。我以另一种方式解决了这个问题，也许可以为您提供帮助：

spring-boot-starter-parent.version ：2.1.1

spring-cloud-dependencies.version ：格林威治R1

安全配置：

@EnableWebFluxSecurity
public class SecurityConfig {

    @Autowired
    private ReactiveAuthenticationManager manager; //custom implementation

    @Bean
    SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        return http
                .authorizeExchange()
                .pathMatchers("/role").hasRole("ADMIN")
                .pathMatchers("/test").access(new HasScope("server")) //custom implementation
                .anyExchange().authenticated()
                .and()
                .httpBasic().disable()
                .oauth2ResourceServer()
                    .jwt()
                    .authenticationManager(manager)
                .and().and()
                .build();
    }
}

ReactiveAuthorizationManager（HasScope）实现： 允许在身份验证对象中搜索范围的助手

public class HasScope implements ReactiveAuthorizationManager<AuthorizationContext> {

    public HasScope(String...scopes) {
        this.scopes = Arrays.asList(scopes);
    }

    private final Collection<String> scopes;

    @Override
    public Mono<AuthorizationDecision> check(Mono<Authentication> authentication, AuthorizationContext object) {
        return authentication
                .flatMap(it -> {
                    OAuth2Authentication auth = (OAuth2Authentication) it;
                    Set<String> requestScopes = auth.getOAuth2Request().getScope();
                    boolean allow = requestScopes.containsAll(scopes);
                    return Mono.just(new AuthorizationDecision(allow));
                });
    }
}

ReactiveAuthenticationManager实现：

这是配置中创建 OAuth2Authentication 的主要组件。错误的access_token响应存在问题，它仅返回状态代码，没有主体响应。

@Component
public class ReactiveAuthenticationManagerImpl implements ReactiveAuthenticationManager {

    private final ResourceServerProperties sso;
    private final WebClient.Builder webClient;
    private final ObjectMapper objectMapper;
    private AuthoritiesExtractor authoritiesExtractor = new FixedAuthoritiesExtractor();

    public ReactiveAuthenticationManagerImpl(ResourceServerProperties sso,
            @Qualifier("loadBalancedWebClient") WebClient.Builder webClient, ObjectMapper objectMapper) {
        this.sso = sso;
        this.webClient = webClient;
        this.objectMapper = objectMapper;
    }

    @Override
    public Mono<Authentication> authenticate(Authentication authentication) {
        return Mono.just(authentication)
                .cast(BearerTokenAuthenticationToken.class)
                .flatMap(it -> getMap(it.getToken()))
                .flatMap(result -> Mono.just(extractAuthentication(result)));
    }

    private OAuth2Authentication extractAuthentication(Map<String, Object> map) {
        Object principal = getPrincipal(map);
        OAuth2Request request = getRequest(map);
        List<GrantedAuthority> authorities = authoritiesExtractor.extractAuthorities(map);
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(principal, "N/A", authorities);
        token.setDetails(map);
        return new OAuth2Authentication(request, token);
    }

    private Object getPrincipal(Map<String, Object> map) {
        if (map.containsKey("principal")) {
            try {
                //that is the case for user authentication
                return objectMapper.convertValue(map.get("principal"), UserPrincipal.class);
            } catch (IllegalArgumentException ex) {
                //that is the case for client authentication
                return objectMapper.convertValue(map.get("principal"), String.class);
            }
        }
        return null;
    }

    @SuppressWarnings({"unchecked"})
    private OAuth2Request getRequest(Map<String, Object> map) {
        Map<String, Object> request = (Map<String, Object>) map.get("oauth2Request");

        String clientId = (String) request.get("clientId");
        Set<String> scope = new LinkedHashSet<>(request.containsKey("scope") ?
                (Collection<String>) request.get("scope") : Collections.emptySet());

        return new OAuth2Request(null, clientId, null, true, new HashSet<>(scope),
                null, null, null, null);
    }

    private Mono<Map<String, Object>> getMap(String accessToken) {
        String uri = sso.getUserInfoUri();
        return webClient.build().get()
                .uri(uri)
                .accept(MediaType.APPLICATION_JSON)
                .header("Authorization", "Bearer " + accessToken)
                .exchange()
                .flatMap(it -> it.bodyToMono(new ParameterizedTypeReference<Map<String, Object>>() {}))
                .onErrorMap(InvalidTokenException.class, mapper -> new InvalidTokenException("Invalid token: " + accessToken));
    }
