yaml

用法与JSON库非常相似：

package main

import (
	"fmt"
	yaml "github.com/shenyuanheli/tools"
)

type Person struct {
	Name string `json:"name"` // Affects YAML field names too.
	Age  int    `json:"age"`
}

func main() {
	// Marshal a Person struct to YAML.
	p := Person{"John", 30}
	y, err := yaml.YamlUtils.Marshal(p)
	if err != nil {
		fmt.Printf("err: %v\n", err)
		return
	}
	fmt.Println(string(y))
	/* Output:
	age: 30
	name: John
	*/

	// Unmarshal the YAML back into a Person struct.
	var p2 Person
	err = yaml.YamlUtils.Unmarshal(y, &p2)
	if err != nil {
		fmt.Printf("err: %v\n", err)
		return
	}
	fmt.Println(p2)
	/* Output:
	{John 30}
	*/
}

yaml.YAMLToJSON and yaml.JSONToYAML methods are also available:

package main

import (
	"fmt"
	yaml "github.com/shenyuanheli/tools"
)

func main() {
	j := []byte(`{"name": "John", "age": 30}`)
	y, err := yaml.YamlUtils.JSONToYAML(j)
	if err != nil {
		fmt.Printf("err: %v\n", err)
		return
	}
	fmt.Println(string(y))
	/* Output:
	name: John
	age: 30
	*/
	j2, err := yaml.YamlUtils.YAMLToJSON(y)
	if err != nil {
		fmt.Printf("err: %v\n", err)
		return
	}
	fmt.Println(string(j2))
	/* Output:
	{"age":30,"name":"John"}
	*/
}
