gateway网关过滤验证请求头然后追加请求头

@Component
public class AuthGlobalFilter implements GlobalFilter, Ordered {
    
	@Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        String url = exchange.getRequest().getURI().getPath();
        log.info("请求地址："+url);
        if(emergentNoticeProperties.getEmergentFlag()){
            throw new SystemEmergentException(ExceptionCode.SYSTEM_EMERGENT_NOTICE.getCode(),String.format("%s，请稍等%s分钟再试",emergentNoticeProperties.getMsg(),emergentNoticeProperties.getMinute()));
        }
        String traceId = UUID.randomUUID().toString();
        log.info("请求链路ID:"+traceId);
        log.info("登录的token 的key是：{}",getTokenKey(token));
        // 从缓存中取login_tokens:token的数据
        String userStr = sops.get(getTokenKey(token));
        if (StringUtils.isBlank(userStr)){
            return setUnauthorizedResponse(exchange,ExceptionCode.TOKEN_ISNOT_VALID.getCode(), "登录状态已过期");
        }
        //注意：网关最好不要依赖其他库，否则容易引发包冲突，因此采用JsonObject解析。
        JSONObject obj = JSONObject.parseObject(userStr);
        String from = obj.getString("from");
        String appCode = obj.getString("appCode");
        // 由于现在使用id的是雪花算法 所以这里要改成getLong
        String userid = obj.getLong("userId").toString();
        if (null==userid || StringUtils.isBlank(from) || StringUtils.isBlank(appCode)){
            return setUnauthorizedResponse(exchange, ExceptionCode.AUTHENTICATION_EXCEPTION.getCode(), "令牌验证失败");
        }
        // 设置过期时间
        redisService.expire(getTokenKey(token), EXPIRE_TIME);

        //设置用户信息到请求，注意，这里是追加头部信息，token信息已经有了
        ServerHttpRequest mutableReq = exchange.getRequest().mutate().header(CacheConstants.DETAILS_USER_ID, userid)
                .header(CacheConstants.DETAILS_CLIENIT, from).header(CacheConstants.DETAILS_FROM_APP,appCode)
                .header(CacheConstants.REQUEST_TRACE,traceId).build();

        ServerWebExchange mutableExchange = exchange.mutate().request(mutableReq).build();
        return chain.filter(mutableExchange);
    }
}
