1.创建结构体

package mainimport (	"fmt"	"github.com/BurntSushi/toml"	"time")type config struct {
   	Title    string	DB       mysql `toml:"mysql"`	App      app	Redis    map[string]redis	Releases releases	Company  company}type app struct {
   	Author  string	Org     string `toml:"organization"`	Mark    string	Release time.Time}type mysql struct {
   	Server  string	Ports   []int	ConnMax int `toml:"connection_max"`	Enabled bool}type redis struct {
   	Host string	Port int}type releases struct {
   	Release []string	Tags    [][]interface{
   }}type company struct {
   	Name   string	Detail detail}type detail struct {
   	Type string	Addr string	ICP  string}

2.配置信息：conf.toml

# 全局信息title = "config"# 应用信息[app]    author = "史布斯"    organization = "Mafool"    release = 2020-05-27T07:32:00Z   # 时间# 数据库配置[mysql]    server = "192.168.1.1"    ports = [ 8001, 8001, 8002 ]     # 数组    connection_max = 5000    enabled = true# Redis主从# 字典对象[redis]    [redis.master]        host = "10.0.0.1"        port = 6379    [redis.slave]        host = "10.0.0.1"        port = 6380# 二维数组[releases]    release = ["dev", "test", "stage", "prod"]    tags = [["dev", "stage", "prod"],[2.2, 2.1]]# 公司信息#对象嵌套[company]    name = "xx科技"[company.detail]    type = "game"    addr = "北京朝阳"    icp = "030173"

3.测试

func main() {
   	var conf config	if _, err := toml.DecodeFile("./conf.toml", &conf); err != nil {
   		panic(err)	}	fmt.Printf("全局信息: %+v\n\n", conf.Title)	fmt.Printf("App信息：%+v\n\n", conf.App)	fmt.Printf("Mysql配置：%+v\n\n", conf.DB)	fmt.Printf("版本信息：%+v\n\n", conf.Releases)	fmt.Printf("Redis主从：%+v\n\n", conf.Redis)	fmt.Printf("企业信息：%+v\n\n", conf.Company)}

4.输出

全局信息: configApp信息：{
   Author:史布斯 Org:Mafool Mark: Release:2020-05-27 07:32:00 +0000 UTC}Mysql配置：{
   Server:192.168.1.1 Ports:[8001 8001 8002] ConnMax:5000 Enabled:true}版本信息：{
   Release:[dev test stage prod] Tags:[[dev stage prod] [2.2 2.1]]}Redis主从：map[master:{
   Host:10.0.0.1 Port:6379} slave:{
   Host:10.0.0.1 Port:6380}]企业信息：{
   Name:xx科技 Detail:{
   Type:game Addr:北京朝阳 ICP:030173}}

1.主结构

package mainimport (	"fmt"	"time"	"github.com/BurntSushi/toml")//总的配置信息type tomlConfig struct {
   	Title   string	Owner   owner	DB      database `toml:"database"`	Servers map[string]server	Clients clients}//用户信息type owner struct {
   	Name string	Org  string `toml:"organization"`	Bio  string	DOB  time.Time}//数据库相关信息type database struct {
   	Server  string	Ports   []int	ConnMax int `toml:"connection_max"`	Enabled bool}//服务器信息type server struct {
   	IP string	DC string}//客户端信息type clients struct {
   	Data  [][]interface{
   }	Hosts []string}

2.example.toml配置信息

Boom.title = "TOML Example"[owner]name = "Tom Preston-Werner"organization = "GitHub"bio = "GitHub Cofounder & CEO Likes tater tots and beer."dob = 1979-05-27T07:32:00Z # First class dates?

3.测试

func main() {
   	//设置结构体对象	var config tomlConfig	//对结构体对象填充信息，文件信息在example.toml上	if _, err := toml.DecodeFile("./example.toml", &config); err != nil {
   		fmt.Println(err)		return	}	//输出标题，全局信息	fmt.Printf("Title: %s\n", config.Title)	//输出owner相关信息	fmt.Printf("Owner: %s (%s, %s), Born: %s\n",		config.Owner.Name,		config.Owner.Org,		config.Owner.Bio,		config.Owner.DOB)	//输出数据库相关信息	fmt.Printf("Database: %s %v (Max conn. %d), Enabled? %v\n",		config.DB.Server,		config.DB.Ports,		config.DB.ConnMax,		config.DB.Enabled)	//输出服务器相关信息	for serverName, server := range config.Servers {
   		fmt.Printf("Server: %s (%s, %s)\n",			serverName,			server.IP,			server.DC)	}	//输出客户端相关信息	fmt.Printf("Client data: %v\n", config.Clients.Data)	fmt.Printf("Client hosts: %v\n", config.Clients.Hosts)}
