go语言之整形和字节数组的转换

//整形转换成字节
func IntToBytes(n int) []byte {
	tmp := int32(n)
	bytesBuffer := bytes.NewBuffer([]byte{})
	binary.Write(bytesBuffer, binary.BigEndian, <span style="font-family: Arial, Helvetica, sans-serif;">tmp</span>)
	return bytesBuffer.Bytes()
}

//字节转换成整形
func BytesToInt(b []byte) int {
	bytesBuffer := bytes.NewBuffer(b)
	var tmp int32
	binary.Read(bytesBuffer, binary.BigEndian, &tmp)
	return int(tmp)
}
