Go 读取 yaml 文件并解析

yaml 文件：

# items.yaml
items:
  - path: aaaa
  - path: bbbb
    weight: "10"
  - path: cccc
    weight: "-5"

Go 代码：

// main.go
package main

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

type Item struct {
	Path string  `yaml:"path"`
	Weight string `yaml:"weight"`
}

type Items struct {
	Items []Item  `yaml:"items"`
}
func main() {
	var items Items
	yamlFile, err := ioutil.ReadFile("items.yaml")
	if err != nil {
		fmt.Printf("failed to read yaml file : %v\n", err)
		return
	}

	err = yaml.Unmarshal(yamlFile, &items)
	if err != nil {
		fmt.Printf("failed to unmarshal : %v\n", err)
		return
	}

	fmt.Println(items)
}

编译执行结果如下：

go build main.go
./main          
{[{aaaa } {bbbb 10} {cccc -5}]}
