二进制序列化binary库
package main
import (
"bytes"
"encoding/binary"
"fmt"
)
type Register struct {
ACTION int32
SID int32
}
func (r *Register) Write() []byte {
buf := new(bytes.Buffer)
var info Register
info.ACTION = 20004
info.SID = 6
err := binary.Write(buf, binary.LittleEndian, info)
if err != nil {
fmt.Println("binary.Write failed:", err)
}
fmt.Printf("% x\n", buf.Bytes())
return buf.Bytes()
}
func (r *Register) Read(b []byte) {
var info Register
buf := bytes.NewBuffer(b)
err := binary.Read(buf, binary.LittleEndian, &info)
if err != nil {
fmt.Println("binary.Read failed:", err)
}
fmt.Print(info)
}
func main() {
b := new(Register)
buf := b.Write()
b.Read(buf)
}Go语言标准库除了提供了binary的之外，还提供了json、csv、xml、gob（类似于 Python 的 "pickle"）、base64等序列化，第三方的也比较多，常见的序列化库如下：
