go讀取配置模塊viper

這個能夠經常和cobra配合。

來個demo

package main

import (
	"fmt"

	"github.com/spf13/viper"
)

func main() {
	v := viper.New()
	v.SetConfigName("linux_config")
	v.AddConfigPath("./config/")
	v.AddConfigPath("%GOPATH/src/")
	v.SetConfigType("yaml")

	if err := v.ReadInConfig(); err != nil {
		fmt.Print("err: %s\n", err)
	}

	fmt.Printf(
		`
		TimeStamp:%s
		CompanyInfomation.Name:%s
		CompanyInfomation.Department:%s `,
		v.Get("TimeStamp"),
		v.Get("CompanyInfomation.Name"),
		v.Get("CompanyInfomation.Department"),
	)
}
