以下是一个简单的QT中UDP组播通讯接收和发送数据的示例代码:
发送数据:
```
QUdpSocket udpSocket;
QByteArray datagram = "Hello World!";
QHostAddress multicastAddress("224.0.0.1");
quint16 port = 5555;
udpSocket.writeDatagram(datagram, multicastAddress, port);
```
接收数据:
```
QUdpSocket udpSocket;
QHostAddress multicastAddress("224.0.0.1");
quint16 port = 5555;
udpSocket.bind(QHostAddress::AnyIPv4, port, QUdpSocket::ShareAddress);
udpSocket.joinMulticastGroup(multicastAddress);
while(udpSocket.hasPendingDatagrams()){
QByteArray datagram;
datagram.resize(udpSocket.pendingDatagramSize());
QHostAddress sender;
quint16 senderPort;
udpSocket.readDatagram(datagram.data(), datagram.size(), &sender, &senderPort);
qDebug() << "Received datagram:" << datagram;
}
```
请注意,上述代码仅作为示例提供,并不保证能够直接使用。在实际使用中,您需要根据您的具体需求对代码进行适当的修改和调整。
