Spring 安全返回 200 而不是 401，如 HttpWebHandlerAdapter 所述

Question

试图弄清楚我是否刚刚在 Spring Security 中发现了一个错误，这是针对最新的 2.4.5 版本的。 HttpWebHandlerAdapter 声明它在日志中返回 401，但 Postman 中的响应为 200。以下是相关的 spring 安全配置/处理程序等。

Spring 安全配置

故障处理程序

@Slf4j
public class AuthenticationFailureHandler implements ServerAuthenticationFailureHandler {
  @Override
  public Mono<Void> onAuthenticationFailure(
      WebFilterExchange webFilterExchange, AuthenticationException exception) {
    log.warn(exception.getMessage());
    ServerHttpResponse response = webFilterExchange.getExchange().getResponse();
    response.setStatusCode(HttpStatus.UNAUTHORIZED);
    response.getHeaders().addIfAbsent(HttpHeaders.LOCATION, "/");
    response.setComplete();
    return Mono.error(exception);
  }
}

JWT 授权转换器。

@Slf4j
@RequiredArgsConstructor
@Component
public class JwtAuthenticationConverter implements ServerAuthenticationConverter {
  private final JwtUtil jwtUtil;

  private Mono<String> extractJwtFromAuthorizationHeader(ServerWebExchange exchange) {
    return Mono.justOrEmpty(exchange.getRequest().getHeaders().get(HttpHeaders.AUTHORIZATION))
        // Remove empty headers/headers with empty string as value
        .filter(
            header ->
                !header.isEmpty()
                    && StringUtils.hasText(header.get(0))
                    && header.get(0).contains("Bearer"))
        .map(header -> header.get(0).replaceAll(AuthConstants.BEARER_PREFIX_REGEX, ""))
        .switchIfEmpty(Mono.error(new InvalidJwtException("Invalid bearer token")));
  }

  @Override
  public Mono<Authentication> convert(ServerWebExchange exchange) {
    return Mono.justOrEmpty(exchange)
        .flatMap(this::extractJwtFromAuthorizationHeader)
        .map(jwtUtil::getAuthenticationFromJwt);
  }
}

身份验证管理器

public class AuthenticationManager extends UserDetailsRepositoryReactiveAuthenticationManager {

  public AuthenticationManager(ReactiveUserDetailsService userDetailsService) {
    super(userDetailsService);
  }

  @Override
  public Mono<Authentication> authenticate(Authentication authentication) {
    return authentication.isAuthenticated()
        ? Mono.just(authentication)
        : super.authenticate(authentication);
  }
}

Answer 1

不是错误，失败处理程序上的 setComplete() 是有问题的行。 没有更多的 200，而日志说 401。
