使用apisix dashboard的时候 会出现一个bug，需要在启动etcd的时候设置ETCD_ADVERTISE_CLIENT_URLS为host域名 而不能使用0.0.0.0

在文件夹下启动

复制代码 
docker-compose -f microservice.yaml up

本地打开 http://localhost:9188 使用admin ，admin 登录

配置路由信息

这里使用的是nacos作为服务发现，具体查看nacos配置

启动以8083端口的服务

复制代码 
dotnet run --urls=http://*:8083

打开浏览器调试下接口

接下来使用网关请求

再启动以8084端口的服务

nacos中出现了两个实例

继续使用网关请求
