Golang 讀取yaml文件

1、新建 conf.yaml 文件

database:
  dbtype: mysql
  dbname: database
  table: table
  username: username
  password: password

application:
  port: 8000

2、新建 conf.go 文件

//package conf
package main

import (
    "fmt"
    "io/ioutil"
    "gopkg.in/yaml.v2"
)

type Conf struct {
    Database Database
    Application Application
}

type Database struct {
    Dbtype string
    Dbname string
    Table string
    Username string
    Password string
}

type Application struct {
    Port string
}

func GetConf() Conf {
    var conf Conf
    // 加載文件
    yamlFile, err := ioutil.ReadFile("/Users/root/Desktop/home/workStations/GoProjects/src/oa.yuchan.cn/conf/conf.yaml")
    if err != nil {
        fmt.Println(err.Error())
    }
    // 將讀取的yaml文件解析為響應的 struct
    err = yaml.Unmarshal(yamlFile, &conf)
    if err != nil {
        fmt.Println(err.Error())
    }
    return conf
}

func main()  {
    fmt.Println(GetConf().Database.Dbname)
}
