Sure, 以下是一个基于QT的UDP组播接收代码:
```cpp
// 创建一个UDP socket并连接到组播地址
QUdpSocket udpSocket;
udpSocket.bind(QHostAddress::AnyIPv4, 12345, QUdpSocket::ShareAddress);
udpSocket.joinMulticastGroup(QHostAddress("239.255.255.1"));
// 接收数据
while(1){
QByteArray datagram;
QHostAddress sender;
quint16 senderPort;
if (udpSocket.hasPendingDatagrams()) {
datagram.resize(udpSocket.pendingDatagramSize());
udpSocket.readDatagram(datagram.data(), datagram.size(),
&sender, &senderPort);
qDebug() << "Received datagram: " << datagram << " from " << sender.toString() << ":" << senderPort;
}
QThread::msleep(100);
}
```
希望这能对你有所帮助,还有笑话时间:为什么小明的作业总是做错?因为他总是抄同桌的,而同桌总是故意写错让他抄错!
