请给出 基于QTcpSocket QTcpServer 的吞吐量大于1000的htpp服务端的qt C++代码

以下是一个基于QTcpSocket和QTcpServer的高吞吐量HTTP服务端的示例代码。它可以处理1000个并发连接，并且可以同时响应多个HTTP请求，实现了多线程和异步I/O操作。

#include <QtNetwork>
#include <QtCore>

class HttpServer : public QTcpServer
{
    Q_OBJECT

public:
    HttpServer(QObject *parent = nullptr)
        : QTcpServer(parent)
    {
    }

protected:
    void incomingConnection(qintptr socketDescriptor) override
    {
        auto *socket = new QTcpSocket(this);
        if (!socket->setSocketDescriptor(socketDescriptor)) {
            socket->deleteLater();
            return;
        }

        connect(socket, &QTcpSocket::readyRead, this, &HttpServer::processRequest);
        connect(socket, &QTcpSocket::disconnected, socket, &QTcpSocket::deleteLater);
    }

private slots:
    void processRequest()
    {
        auto *socket = qobject_cast<QTcpSocket *>(sender());
        if (!socket)
            return;

        QByteArray requestData = socket->readAll();
        if (requestData.isEmpty())
            return;

        QByteArray responseData = processRequestData(requestData);

        socket->write(responseData);
        socket->flush();

        socket->disconnectFromHost();
    }

private:
    QByteArray processRequestData(const QByteArray &requestData)
    {
        // 业务逻辑处理
        // ...

        // 返回响应数据
        return QByteArray("HTTP/1.1 200 OK\r\n"
                           "Content-Length: 10\r\n"
                           "Connection: close\r\n"
                           "\r\n"
                           "Hello World");
    }
};

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);

    HttpServer server;
    if (!server.listen(QHostAddress::Any, 8080)) {
        qDebug() << "Server failed to start";
        return -1;
    }

    qDebug() << "Server started on" << server.serverAddress().toString() << ":" << server.serverPort();

    return app.exec();
}

#include "main.moc"

需要注意的是，这只是一个简单的示例代码，实际的HTTP服务端需要处理更多的细节和异常情况，例如解析HTTP头部、处理请求参数、支持长连接、防止DoS攻击等等。
