添加此应用程序的Qt套接字代码以启用两台PC之间的聊天

// 引入必要的头文件
#include <QtNetwork/QTcpSocket>
#include <QtNetwork/QHostAddress>

// 创建一个QTcpSocket对象
QTcpSocket* socket = new QTcpSocket(this);

// 连接到服务器
QHostAddress serverAddress("服务器IP地址");
quint16 serverPort = 1234; // 服务器端口号
socket->connectToHost(serverAddress, serverPort);

// 连接成功后，发送和接收数据
connect(socket, &QTcpSocket::connected, this, [=]() {
    // 连接成功后的操作
    qDebug() << "Connected to server";

    // 发送数据
    QString message = "Hello, server!";
    socket->write(message.toUtf8());

    // 接收数据
    connect(socket, &QTcpSocket::readyRead, this, [=]() {
        QByteArray data = socket->readAll();
        QString receivedMessage = QString::fromUtf8(data);
        qDebug() << "Received message: " << receivedMessage;
    });
});

// 处理连接错误
connect(socket, &QTcpSocket::errorOccurred, this, [=](QAbstractSocket::SocketError socketError) {
    qDebug() << "Socket error: " << socketError;
});
