用qt写一个 tcp服务器设置通信速率的程序

好的，我了解了您的要求。以下是一个用Qt写的TCP服务器设置通信速率的程序的示例代码：

#include <QtNetwork>

class Server : public QObject {
    Q_OBJECT
public:
    Server(QObject *parent = nullptr) : QObject(parent) {
        server = new QTcpServer(this);
        connect(server, &QTcpServer::newConnection, this, &Server::newConnection);
        bool ok = server->listen(QHostAddress::Any, 1234);
        if (!ok) {
            qFatal("Could not start server");
        } else {
            qDebug() << "Server started";
        }
    }

public slots:
    void newConnection() {
        QTcpSocket *socket = server->nextPendingConnection();
        qDebug() << "New connection from " << socket->peerAddress().toString();
        connect(socket, &QTcpSocket::readyRead, this, &Server::readyRead);
        connect(socket, &QTcpSocket::disconnected, this, &Server::disconnected);
        // Set the communication speed to 1 MB/s
        socket->setSocketOption(QAbstractSocket::LowDelayOption, 1);
        socket->setReadBufferSize(1024 * 1024); // Set read buffer to 1 MB
    }

    void readyRead() {
        QTcpSocket *socket = qobject_cast<QTcpSocket*>(sender());
        if (!socket) {
            return;
        }
        qDebug() << "Data received from " << socket->peerAddress().toString();
        QByteArray data = socket->readAll();
        // Process received data...
    }

    void disconnected() {
        QTcpSocket *socket = qobject_cast<QTcpSocket*>(sender());
        if (!socket) {
            return;
        }
        qDebug() << "Connection closed by " << socket->peerAddress().toString();
        socket->deleteLater();
    }

private:
    QTcpServer *server;
};

int main(int argc, char *argv[]) {
    QCoreApplication app(argc, argv);
    Server server;
    return app.exec();
}

#include "main.moc"

这个程序创建了一个TCP服务器，监听端口1234。当有客户端连接时，服务器将设置通信速率为1 MB/s，设置读缓冲区为1 MB，并与客户端建立连接。当客户端发送数据时，服务器将读取数据并处理。当客户端关闭连接时，服务器将关闭连接。请注意，此示例仅用于演示用途，您需要根据实际情况进行修改。
