Go语言中序列化与反序列化示例详解

// 数据序列化
func Serialize(v interface{})([]byte, error)

// fix参数用于添加前缀
//idt参数用于指定你想要缩进的方式
func serialization (v interface{}, fix, idt string) ([]byte, error)

//struct
import (
	"encoding/json"
	"fmt"
)

type Student struct {
	Id   int64
	Name string
	Desc string
}

 func fn() {
	std := &Student{0, "Ruoshui", "this to Go"}
	data, err := json.MarshalIndent(std, "", "   ")  
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(string(data))
}
//array、slice、map
func fc() {
	s := []string{"Go", "java", "php"}
	d, _ := json.MarshalIndent(s, "", "\t")
	fmt.Println(string(d))
	
	m := map[string]string{
		"id": "0",
		"name":"ruoshui",
		"des": "this to Go",
	}
	bytes, _ := json.Marshal(m)
	fmt.Println(string(bytes))
}

//返回带引号字符串
type Marshaler interface {
    MarshalJSON() ([]byte, error) 
}
type Unmarshaler interface {
	UnmarshalJSON([]byte) error
}

//返回不带引号的字符串
type TextMarshaler interface {
    MarshalText() (text []byte, err error) 
}
type TextUnmarshaler interface {
	UnmarshalText(text []byte) error
}

func Unmarshal(data [] byte, arbitrarily interface{}) error

//struct
type Student struct {
	Id int64    `json:"id,string"`
	Name string `json:"name,omitempty"`
	Desc string `json:"desc"`
}

func fn() {
	str := `{"id":"0", "name":"ruoshui", "desc":"new Std"}`
	var st Student
	_ = json.Unmarshal([]byte(str), &st)
	fmt.Println(st)
}
//slice和map
func f() {
	slice := `["java", "php", "go"]`
	var sli []string
	_ = json.Unmarshal([]byte(slice), &sli)
	fmt.Println(sli)


	mapStr := `{"a":"java", "b":"node", "c":"php"}`
	var newMap map[string]string
	_ = json.Unmarshal([]byte(mapStr), &newMap)
	fmt.Println(newMap)
