如何设置QTcpSocket心跳间隔？

socket->setSocketOption(QAbstractSocket::KeepAliveOption, 1);

QTcpSocket *socket = new QTcpSocket(this);
socket->connectToHost("hostname", port);

// 设置心跳间隔为10秒
socket->setSocketOption(QAbstractSocket::KeepAliveOption, 1);

// 获取套接字描述符
qintptr socketDescriptor = socket->socketDescriptor();

#ifdef Q_OS_WIN
// 在Windows平台上设置心跳间隔
DWORD keepAlive = 1;
DWORD keepAliveInterval = 10 * 1000; // 10秒
DWORD retSize;
WSAIoctl(socketDescriptor, SIO_KEEPALIVE_VALS, &keepAliveInterval, sizeof(keepAliveInterval), &keepAlive, sizeof(keepAlive), &retSize, nullptr, nullptr);
#else
// 在其他平台上设置心跳间隔
int keepAlive = 1;
int keepAliveInterval = 10; // 10秒
setsockopt(socketDescriptor, SOL_SOCKET, SO_KEEPALIVE, &keepAlive, sizeof(keepAlive));
setsockopt(socketDescriptor, IPPROTO_TCP, TCP_KEEPIDLE, &keepAliveInterval, sizeof(keepAliveInterval));
#endif
