我正在尝试创建一些随机 int 数组并将其写入xyz.txtGolang 中的文件。如何将ids哪个是int数组转换为byte数组,作为参数file.Write接受[]byte。将随机整数数组写入文本文件的正确方法是什么。func main() { var id int var ids []int var count int f, err := os.Create("xyz.txt") check(err) defer f.C...

比如n2,数值0x5AF3ACA48850,转成byte,再转成int,却变成了-1398503344 很奇怪,第一个数pqStr解出来的int值不是0x5AF3ACA48850 代码: package main import ( "bytes" "encoding/binary" "fmt" "strconv" ) func int2Str16(n int) string { return strconv.FormatInt(int64(n), 16) } func int2bytes...

Golang语言--将byte的int转换 在使用golang做数据传输的时候,会经常遇到byte与int的互转,但golang并没有现成的方法,因此只能通过binary包来解决 所以,需要 :import "encoding/binary",又因为是byte的转换,所以还涉及到了bytes:import "bytes" 代码如下:
(ipstring)int64{ret:=big.NewInt(0)ret.SetBytes(net.ParseIP(ip).To4())returnret.Int64()}funcmain(){ip:="192.168.78.123"ipInt:=InetAtoN(ip)fmt.Printf("convert string ip [%s] to int: %d\n",ip,ipInt)fmt.Printf("convert int ip [%d] to string: %s\n",ipInt,InetNtoA(ipInt))...
