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
