问题描述
我有 int
,其中包含网络字节顺序的IP地址,我想将其转换为 InetAddress
对象。我看到有一个 InetAddress
构造函数,它接受 byte []
,是否需要转换 int
首先到 byte []
,还是有另一种方式?
I have an int
which contains an IP address in network byte order, which I would like to convert to an InetAddress
object. I see that there is an InetAddress
constructor that takes a byte[]
, is it necessary to convert the int
to a byte[]
first, or is there another way?
推荐答案
这应该有效:
int ipAddress = ....
byte[] bytes = BigInteger.valueOf(ipAddress).toByteArray();
InetAddress address = InetAddress.getByAddress(bytes);
您可能必须交换字节数组的顺序,我无法弄清楚数组是否存在将以正确的顺序生成。
You might have to swap the order of the byte array, I can't figure out if the array will be generated in the correct order.
