Gateway详细内容可参考博客：

[SpringCloud-GateWay（五）\_骑着蜗牛打天下的博客-CSDN博客][SpringCloud-GateWay_-CSDN]

**注意：**

Gateway与Nginx区别：Gateway是服务网关，Nginx是流量网关；

Ribbon与Nginx区别：Ribbon是客户端负载均衡，Nginx是服务端负载均衡；

                - AddRequestParameter=red, blue
                - AddResponseHeader=name,zhangbozhi

            - AddResponseHeader=company,266
    #        - AddRequestHeader=traceid,5nifaiea8787808877

可把服务a多端口启动，使用gateway转发时默认为轮询算法
