前端加密功能

前端提供简单的AES对称加密算法，注意key 和后端网关配置相同，这里打包混淆后，相对安全。 （lun-ui\src\store\modules\user.js、base-gateway-dev.yml）

后端解密功能

使用hutool提供的工具类进行解密

public class PasswordDecoderFilter extends AbstractGatewayFilterFactory {
    @Override
    public GatewayFilter apply(Object config) {
        return (exchange, chain) -> {
            ServerHttpRequest request = exchange.getRequest();
            URI uri = exchange.getRequest().getURI();
            String queryParam = uri.getRawQuery();
            Map<String, String> paramMap = HttpUtil.decodeParamMap(queryParam, CharsetUtil.UTF_8);

            String password = paramMap.get(PASSWORD);
            if (StrUtil.isNotBlank(password)) {
                try {
                    password = decryptAES(password, encodeKey);
                } catch (Exception e) {
                    log.error("密码解密失败:{}", password);
                    return Mono.error(e);
                }
                paramMap.put(PASSWORD, password.trim());
            }

            URI newUri = UriComponentsBuilder.fromUri(uri)
                .replaceQuery(HttpUtil.toParams(paramMap))
                .build(true)
                .toUri();

            ServerHttpRequest newRequest = exchange.getRequest().mutate().uri(newUri).build();
            return chain.filter(exchange.mutate().request(newRequest).build());
        };
    }
}
