Golang toml完全解析示例 Go语言

配置管理基于TOML v0.4.0的配置管理

Toml语法可查看Toml官方文档或中文文档。
GO客户端：https://github.com/BurntSushi/toml，这里是官方使用示例。

安装Go-toml

# 安装toml-go客户端 go get github.com/BurntSushi/toml# 验证toml语法 go get github.com/BurntSushi/toml/cmd/tomlv tomlv some-toml-file.toml

示例1 example.toml

示例2

自定义字段类型（重新实现encoding.Unmarshal接口）反序列化方法
实现toml对象数组格式

package mainimport ( "fmt" "github.com/BurntSushi/toml" "log" "time" )type Song struct { Name string Durduration `toml:"duration"` }type duration struct { time.Duration }func (d *duration) UnmarshalText(text []byte) error { var err error d.Duration, err = time.ParseDuration(string(text)) return err }func main() { blob := ` [[song]] name = "天路" duration = "4m49s"[[song]] name = "忘情水" duration = "8m03s" ` var songs struct { Song []Song } // 使用 toml.Decode if _, err := toml.Decode(blob, &songs); err != nil { log.Fatal(err) } fmt.Printf("%+v\n", songs) }

示例3

【Golang toml完全解析示例】对象数组

type redis struct { Host string Port int Auth string }type sentinel struct { Member []redis }func main() { var rds = ` [redis] host = "127.0.0.1" port = 26379[sentinel] [[sentinel.member]] host = "127.0.0.1" port = 26379 #auth = "123456" [[sentinel.member]] host = "127.0.0.1" port = 26380 #auth = "123456"[cluster] [[cluster.member]] host = "127.0.0.1" port = 11111 [[cluster.member]] host = "127.0.0.1" port = 22222 ` var config struct{ Redis redis Sentinel sentinel } if _, err := toml.Decode(rds, &config); err != nil { panic(err) } fmt.Println(config) }
