帮我写个基于qt的多线程udp服务器源码

好的，我可以回答这个问题。以下是基于Qt的多线程UDP服务器的源代码：

#include <QtNetwork/QUdpSocket>
#include <QtCore/QThread>

class UdpServer : public QObject
{
    Q_OBJECT

public:
    UdpServer(QObject *parent = nullptr) : QObject(parent) {}

public slots:
    void startServer()
    {
        QUdpSocket *socket = new QUdpSocket(this);
        socket->bind(QHostAddress::Any, 1234);

        while (true) {
            QByteArray datagram;
            datagram.resize(socket->pendingDatagramSize());
            QHostAddress sender;
            quint16 senderPort;

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

            WorkerThread *workerThread = new WorkerThread(datagram, sender, senderPort);
            connect(workerThread, &WorkerThread::resultReady, this, &UdpServer::sendResponse);
            workerThread->start();
        }
    }

signals:
    void responseReady(QByteArray response, QHostAddress address, quint16 port);

private slots:
    void sendResponse(QByteArray response, QHostAddress address, quint16 port)
    {
        QUdpSocket *socket = new QUdpSocket(this);
        socket->writeDatagram(response, address, port);
    }
};

class WorkerThread : public QThread
{
    Q_OBJECT

public:
    WorkerThread(QByteArray datagram, QHostAddress sender, quint16 senderPort)
        : m_datagram(datagram), m_sender(sender), m_senderPort(senderPort) {}

signals:
    void resultReady(QByteArray response, QHostAddress address, quint16 port);

protected:
    void run() override
    {
        // Do some work with the datagram
        QByteArray response = m_datagram.toUpper();

        emit resultReady(response, m_sender, m_senderPort);
    }

private:
    QByteArray m_datagram;
    QHostAddress m_sender;
    quint16 m_senderPort;
};

这个服务器使用了Qt的QUdpSocket类来接收和发送UDP数据包。它使用了多线程来处理每个接收到的数据包，以便不会阻塞主线程。每个工作线程都会将接收到的数据包转换为大写字母，并将响应发送回客户端。
