1.下载依赖

go get -u github.com/go-ini/ini

2.创建conf.ini文件

//conf/app.ini配置文件
[database]
Type = mysql
User = root
Password = 
Host = 127.0.0.1:3306
Name = 
 

3.在setting中配置参数

type Database struct {
	Type        string
	User        string
	Password    string
	Host        string
	Name        string
}
var cfg *ini.File
var DatabaseSetting =&Database{}
cfg,_ =ini.Load("conf/app.ini")
cfg.Section("database").MapTo(DatabaseSetting)

4.使用配置文件

sec:= setting.DatabaseSetting
fmt.Sprintf("%s:%s@tcp(%s)/%s?charset=utf8&parseTime=True&loc=Local",
		sec.User,
		sec.Password,
		sec.Host,
		sec.Name)

对以后修改参数比较方便
