在gateway中配置uri，有三种方式，包括：

1.WebSocket方式：uri: ws://localhost:9000

2.HTTP方式：uri: http://localhost:8130/

3.LB（服务名）方式：uri: lb://brilliance-consu

在gateway中配置uri配置有三种方式，包括
第一种：ws(websocket)方式: uri: ws://localhost:9000
第二种：localhost:8130/
第三种：lb(注册中心中服务名字)方式: uri: lb://brilliance-consumer

其中ws和brilliance_consumer
