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
