QTcpServer 使用的简单示例-QT开发中文网

以下是一个简单的示例代码，展示了如何使用QTcpServer创建一个基本的TCP服务器：

”`cpp #include #include #include

class MyServer : public QTcpServer {

Q_OBJECT

public:

MyServer(QObject *parent = nullptr)
    : QTcpServer(parent)
{
    // 监听指定端口
    listen(QHostAddress::Any, 12345);
    qDebug() << "Server started";
}

protected:

void incomingConnection(qintptr socketDescriptor) override
{
    // 创建一个新的socket连接
    QTcpSocket *clientSocket = new QTcpSocket(this);

    // 设置套接字描述符
    clientSocket->setSocketDescriptor(socketDescriptor);

    // 连接信号和槽函数
    connect(clientSocket, &QTcpSocket::readyRead, this, &MyServer::readData);
    connect(clientSocket, &QTcpSocket::disconnected, this, &MyServer::disconnectClient);

    qDebug() << "New client connected:" << clientSocket->peerAddress().toString();

    // 向客户端发送欢迎消息
    QString welcomeMsg = "Welcome to the server!";
    clientSocket->write(welcomeMsg.toUtf8());
}

private slots:

void readData()
{
    QTcpSocket *clientSocket = static_cast<QTcpSocket*>(sender());

    while (clientSocket->bytesAvailable() > 0)
    {
        QByteArray data = clientSo<br/><br/><br/><font size=1 color=#CCCCCC>内容由零声教学AI助手提供，问题来源于学员提问</font>
