Go语言代码优化

string和[]byte之间的下相互转换

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

func string2bytes(s string) []byte {
	return *(*[]byte)(unsafe.Pointer(&s))
}

func bytes2string(b []byte) string {
	return *(*string)(unsafe.Pointer(&b))
}

type Man struct {
	Age  int
	Name string
	Job  *Job
}

type Job struct {
	Name string
}

func main() {
	m := Man{
		Age:  12,
		Name: "xiaoqiang",
		Job: &Job{
			Name: "engineer",
		},
	}
	sl, _ := json.Marshal(m)
	s := bytes2string(sl)
	fmt.Println(s)
	var n Man
	_ = json.Unmarshal(string2bytes(s), &n)
	fmt.Println(n, n.Job)
}
