代码:

package main

	"fmt"
	"io"
	"os"
)

func main() {
	file, err := os.OpenFile("test", os.O_RDONLY, os.ModePerm)
	if err != nil {
		defer file.Close()
		os.Exit(0)
	}
	file.Seek(8, 0)
	fmt.Println("Success Open File")
	var buffer bytes.Buffer
	io.CopyN(&buffer, file, 8)
	_bytes := buffer.Bytes()
	var magic []byte = []byte{0x12, 0x31, 0x22, 0x22, 0x22, 0x22, 0x22, 0x22}
	for _, byte := range _bytes {
		fmt.Printf("%02X ", byte)
	}
	fmt.Println()
	if bytes.Compare(magic, _bytes) == 0 {
		fmt.Println("Equal")
	}
}

结果:

	Success Open File
	12 31 22 22 22 22 22 22 
	Equal
