pack("H*", $string) 转化成这样:

//16进制字符串转[]bytefunc HexToByte(hex string) []byte {    length := len(hex) / 2    slice := make([]byte, length)    rs := []rune(hex)    for i := 0; i < length; i++ {        s := string(rs[i*2 : i*2+2])        value, _ := strconv.ParseInt(s, 16, 10)        slice[i] = byte(value & 0xFF)    }    return slice}
