go 语言中 byte 与 int 互转, string 与 byte 互转

package main

import "bytes"
import "encoding/binary"
import "fmt"
import "strings"

func main() {
	b := []byte{0x00,0x00,0x03,0xe8}
	bin_buf := bytes.NewBuffer(b)
	var x int32
	
	binary.Read(bin_buf, binary.BigEndian, &x)
	fmt.Println(x)
	
	fmt.Println(strings.Repeat("~", 20))
	
	x = 1000
	bin_buf = bytes.NewBuffer([]byte{})
	binary.Write(bin_buf, binary.BigEndian, x)
	fmt.Println(bin_buf.Bytes())
	
	str2 := "hello"

	data2 := []byte(str2)
	fmt.Println(data2)

	str2 = string(data2[:])
	fmt.Println(str2)

}

编译输出:

C:\Go\bin\go.exe run conver.go
1000

[0 0 3 232]
[104 101 108 108 111]
