如何在一个应用程序中正确使用Qt中的多个QUdpSockets

#include <QUdpSocket>

QUdpSocket* socket1 = new QUdpSocket(this);
QUdpSocket* socket2 = new QUdpSocket(this);
// 可以根据需要创建更多的QUdpSocket对象

socket1->bind(QHostAddress::Any, 1234);
socket2->bind(QHostAddress::Any, 5678);
// 可以为每个QUdpSocket对象绑定不同的端口

connect(socket1, SIGNAL(readyRead()), this, SLOT(processPendingDatagrams1()));
connect(socket2, SIGNAL(readyRead()), this, SLOT(processPendingDatagrams2()));
// 可以为每个QUdpSocket对象连接不同的槽函数

void MyClass::processPendingDatagrams1()
{
    while (socket1->hasPendingDatagrams())
    {
        QByteArray datagram;
        datagram.resize(socket1->pendingDatagramSize());
        QHostAddress sender;
        quint16 senderPort;

        socket1->readDatagram(datagram.data(), datagram.size(), &sender, &senderPort);

        // 处理接收到的数据
    }
}

void MyClass::processPendingDatagrams2()
{
    while (socket2->hasPendingDatagrams())
    {
        QByteArray datagram;
        datagram.resize(socket2->pendingDatagramSize());
        QHostAddress sender;
        quint16 senderPort;

        socket2->readDatagram(datagram.data(), datagram.size(), &sender, &senderPort);

        // 处理接收到的数据
    }
}

QByteArray datagram = "Hello, World!";
QHostAddress receiverAddress = QHostAddress::LocalHost;
quint16 receiverPort = 1234;

socket1->writeDatagram(datagram, receiverAddress, receiverPort);

delete socket1;
delete socket2;
