Yaml 檔案內容（test.yaml）

cache:
  enable : false
  list : [redis,mongoDB]
mysql:
  user : root
  password : wangJiLe
  host : 11.22.33.44
  port : 3306
  name : world

Go解析test.yaml檔案（gopkg.in/yaml.v2包）

• Goalng版本1.16.5

go mod init demo
go get gopkg.in/yaml.v2

解析程式碼如下

package main

import (
	"fmt"
	"io/ioutil"

	yaml "gopkg.in/yaml.v2"
)

type Yaml struct {
	Cache struct {
		Enable bool     `yaml:"enable"`
		List   []string `yaml:"list"`
	}
	MySQL struct {
		User     string `yaml:"user"`
		Password string `yaml:"password"`
		Host     string `yaml:"host"`
		Port     string `yaml:"port"`
		Name     string `yaml:"name"`
	}
}

func main() {
	var conf Yaml
	yamlFile, err := ioutil.ReadFile("test.yaml")
	if err != nil {
		fmt.Println(err)
		return
	}
	if err = yaml.Unmarshal(yamlFile, &conf); err != nil {
		fmt.Println(err)
		return
	}
	fmt.Println(conf.MySQL.Host)
	fmt.Println(conf.MySQL.Name)
	fmt.Println(conf.MySQL.Password)
	fmt.Println(conf.MySQL.Port)
	fmt.Println(conf.MySQL.User)
	fmt.Println(conf.Cache.Enable)

	for _, v := range conf.Cache.List {
		fmt.Println("Cache:", v)
	}
}

 

編譯，執行

go build
