go get gopkg.in/ini.v1

配置

tmp    my.ini    main.go

my.ini# possible values : production, developmentapp_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 usehttp_port = 9999# Redirect to correct domain if host header does not match domain# Prevents DNS rebinding attacksenforce_domain = true

main.gopackage mainimport (    "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: developmentData Path: /home/git/grafanaServer Protocol: httpEmail Protocol: smtpPort Number: (int) 9999Enforce Domain: (bool) true
