QUdpSocket如何获得发送端的地址，端口 [复制链接]

接收到数据后，如何判断数据源IP和端口？

QUdpSocket的readDatagram，第三个参数就是地址，第四个参数是端口
qint64    readDatagram(char * data, qint64 maxSize, QHostAddress * address = 0, quint16 * port = 0)
参见帮助文档
void Server::readPendingDatagrams()
{
    while (udpSocket->hasPendingDatagrams()) {
        QByteArray datagram;
        datagram.resize(udpSocket->pendingDatagramSize());
        QHostAddress sender;
        quint16 senderPort;

        udpSocket->readDatagram(datagram.data(), datagram.size(),
                                &sender, &senderPort);

        processTheDatagram(datagram);
    }
}

谢谢啦，我真是傻了，竟然忘记去看看这个参数。。。
