- 使用ini.v1配合fsnotify实现:
1 解析ini配置文件
2 监听配置文件的变化热更新配置
import (
"github.com/fsnotify/fsnotify"
"github.com/sirupsen/logrus"
"gopkg.in/ini.v1"
"io/ioutil"
)
var iniConf *ini.File
const confPath = "main.ini"
func init() {
var err error
iniConf, err = ini.Load(confPath)
if err != nil {
logrus.Panicf("load conf error: [%s]", err)
}
iniConf.BlockMode = false
// 增加热更新能力
watcher, err := fsnotify.NewWatcher()
if err != nil {
logrus.Panicf("new watcher error: [%s]", err)
}
go func() {
for {
select {
case event := <-watcher.Events:
if event.Op&fsnotify.Write == fsnotify.Write {
bytes, err := ioutil.ReadFile(confPath)
if err != nil {
logrus.Errorf("read conf error: [%s]", err)
break
}
logrus.Infof("modified conf file:%s", string(bytes))
newConf, err := ini.Load(confPath)

}
}
}()
if err := watcher.Add(confPath); err != nil {
logrus.Panicf("add watcher file error: [%s]", err)
}
}
func GetString(section, key, defaultValue string) string {
return iniConf.Section(section).Key(key).MustString(defaultValue)

func GetInt(section, key string, defaultValue int) int {
