c++ QTcpServer

cpp：

   server = new QTcpServer(this);
    connect(server, &QTcpServer::newConnection, this, &PythonConsole::newConnection);
    if (!server->listen(QHostAddress::Any, 8000)) {
        qWarning("Unable to start the server: %s", qPrintable(server->errorString()));
    }

调试：

    connect(server, &QTcpServer::newConnection, [this]() {
        QTcpSocket *socket = server->nextPendingConnection();
        qDebug() << "New connection from:" << socket->peerAddress().toString();
    });

void PythonConsole::newConnection()
{
    clientConnection = server->nextPendingConnection();
    connect(clientConnection, &QTcpSocket::readyRead, this, &PythonConsole::readClient);
}

void PythonConsole::readClient()
{
    QByteArray data = clientConnection->readAll();
    QString command = QString::fromUtf8(data);
    runSource(command);
    clientConnection->close();
}

    QTcpServer *server;
