go 读取 ini文件 并修改

安装

官方网站
https://ini.unknwon.io/docs/intro/getting_started

go get gopkg.in/ini.v1

配置

tmp
 my.ini
 main.go

my.ini
# possible values : production, development
app_mode = development
[paths]
# Path to where grafana can store temp files, sessions, and the sqlite3 db (if that is used)
data = /home/git/grafana
[server]
# Protocol (http or https)
protocol = http
# The http port to use
http_port = 9999
# Redirect to correct domain if host header does not match domain
# Prevents DNS rebinding attacks
enforce_domain = true

main.go
package main
import (
 "fmt"
 "os"
 "gopkg.in/ini.v1"
)
func main() {
 dir, _ := os.Getwd()
 fmt.Println(dir)
 path := dir + "\\src\\test\\tmp\\" // windows下的路径 需要注意修改一下 默认是gopath
 path_name := path + "my.ini"
 cfg, err := ini.Load(path_name)
 if err != nil {
 fmt.Printf("Fail to read file: %v", err)
 os.Exit(1)
 }
 // 典型读取操作,默认分区可以使用空字符串表示
 fmt.Println("App Mode:", cfg.Section("").Key("app_mode").String())
 fmt.Println("Data Path:", cfg.Section("paths").Key("data").String())
 // 我们可以做一些候选值限制的操作
 fmt.Println("Server Protocol:",
 cfg.Section("server").Key("protocol").In("http", []string{"http", "https"}))
 // 如果读取的值不在候选列表内,则会回退使用提供的默认值
 fmt.Println("Email Protocol:",
 cfg.Section("server").Key("protocol").In("smtp", []string{"imap", "smtp"}))
 // 试一试自动类型转换
 fmt.Printf("Port Number: (%[1]T) %[1]d\n", cfg.Section("server").Key("http_port").MustInt(9999))
 fmt.Printf("Enforce Domain: (%[1]T) %[1]v\n", cfg.Section("server").Key("enforce_domain").MustBool(false))
 // 差不多了,修改某个值然后进行保存
 cfg.Section("").Key("app_mode").SetValue("production")
 cfg.SaveTo(path+"my.ini.local")
}

注意路径

结果

App Mode: development
Data Path: /home/git/grafana
Server Protocol: http
Email Protocol: smtp
Port Number: (int) 9999
Enforce Domain: (bool) true
