[go-micro实战]5 micro自带命令行（有问题）

使用命令行，运行出错，暂时无法解决

package main

import (
	"flag"
	"fmt"
	"gitee.com/Hind3ight/easy-go-micro/go-micro/model"
	"github.com/gin-gonic/gin"
	"github.com/micro/go-micro/registry"
	"github.com/micro/go-micro/web"
	"github.com/micro/go-plugins/registry/consul" // micro版本变迁
	"log"

)

func main() {
	consulReg := consul.NewRegistry(registry.Addrs("192.168.31.246:8500"))
	r := gin.Default()
	r.Handle("GET", "/news", func(c *gin.Context) {
		c.String(200, "new api")
	})
	prodGroup := r.Group("v1")
	{
		prodGroup.Handle("GET", "/prods", func(c *gin.Context) {
			c.JSON(200, gin.H{
				"data": model.GenFakerProdList(4),
			})
		})
	}
	server := web.NewService(
		web.Name("prodService"),
		web.Address(flagParser()),
		web.Handler(r),
		web.Registry(consulReg),
	)

	err := server.Run()
	if err != nil {
		log.Fatal("Server Run error: ", err)
	}
}

// simple 自定义命令行解析
func flagParser() string {
	serverAddress := flag.String("server_address", ":8080", "服务端口")
	flag.Parse()
	fmt.Println("端口号：", *serverAddress)
	return *serverAddress
}

先自己写个函数简单解决
