代码目录：

main.go

package main

import "cobraDemo/cmd"

func main() {
	cmd.Execute()
}

root.go

package cmd

import (
	"fmt"
	"github.com/spf13/cobra"
	"os"

	"github.com/spf13/viper"
)

var cfgFile string
//增加name参数
var name string

var rootCmd = &cobra.Command{
	Use:   "demo",
	Short: "A brief description of your application",
	Long: `A longer description that spans multiple lines and likely contains
examples and usage of using your application. For example:

Cobra is a CLI library for Go that empowers applications.
This application is a tool to generate the needed files
to quickly create a Cobra application.`,
	Run: func(cmd *cobra.Command, args []string) {
		//赋值
		fmt.Println(name)
	},
}
