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
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
在log中的access.log 可以查看到网关请求到不同端口的服务
几个注意点：
1.etcd的ETCD_ADVERTISE_CLIENT_URLS 需要更换为host域名不能使用0.0.0.0
2.apisix的nacos配置在 config.yaml中的discovery
尽量使用host名称
