  1. 安装
go get gopkg.in/yaml.v3
  1. 创建yaml
Mysql:
  Host: 192.168.214.134
  Port: 3306
  UserName: ww
  Password: ww
  Database: go_db
  Charset: utf8mb4
  ParseTime: true
  Loc: Local
  ListValue:
    - haha
    - test
    - vv
JWTSecret: nidaye
  1. 定义结构体
type Mysql struct {
	Host      string   `yaml:"Host"`
	Port      int      `yaml:"Port"`
	UserName  string   `yaml:"UserName"`
	Password  string   `yaml:"Password"`
	Database  string   `yaml:"Database"`
	Charset   string   `yaml:"Charset"`
	ParseTime bool     `yaml:"ParseTime"`
	Loc       string   `yaml:"Loc"`
	ListValue []string `yaml:"ListValue"`
}

type YamlStruct struct {
	Mysql     Mysql  `yaml:"Mysql"`
	JWTSecret string `yaml:"JWTSecret"`
}
  1. 读取
package main

import (
	"fmt"
	"os"

	"gopkg.in/yaml.v3"
)

type Mysql struct {
	Host      string   `yaml:"Host"`
	Port      int      `yaml:"Port"`
	UserName  string   `yaml:"UserName"`
	Password  string   `yaml:"Password"`
	Database  string   `yaml:"Database"`
	Charset   string   `yaml:"Charset"`
	ParseTime bool     `yaml:"ParseTime"`
	Loc       string   `yaml:"Loc"`
	ListValue []string `yaml:"ListValue"`
}

type YamlStruct struct {
	Mysql     Mysql  `yaml:"Mysql"`
	JWTSecret string `yaml:"JWTSecret"`
}

func ReadConf(filename string) (*YamlStruct, error) {
	buf, err := os.ReadFile(filename)
	c := YamlStruct{}
	if err != nil {
		return nil, err
	} else {
		err2 := yaml.Unmarshal(buf, &c)
		if err2 != nil {
			return nil, err2
		} else {
			return &c, nil
		}
	}
}

func main() {
	c, _ := ReadConf("./config.yaml")
	fmt.Printf("c: %v\n", c.Mysql.ListValue)

}
