1.创建结构体
package main
import (
"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: config
App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 main
import (
"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
# This is a TOML document. 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? Why not?
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
connection_max = 5000
enabled = true
[servers]
[servers.alpha]
ip = "10.0.0.1"
dc = "eqdc10"
[servers.beta]
ip = "10.0.0.2"
dc = "eqdc10"
[clients]
data = [ ["gamma", "delta"], [1, 2] ]
# Line breaks are OK when inside arrays
hosts = ["alpha", "omega"]
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)
}
