Yaml 文件内容（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文件（gopkg.in/yaml.v2包）
- Goalng版本1.16.5
go mod init demo
go get gopkg.in/yaml.v2
解析代码如下
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)
}
}
编译，运行
go build
./demo
