Qt socket測試

if (tcpSocketObj->state()==QAbstractSocket::SocketState::ConnectedState)
{
    qDebug() << "send  data:"<<dataStr;
    tcpSocketObj->write(dataStr.toUtf8());
}

if (tcpSocketObj->state() == QAbstractSocket::ConnectedState) 
{
    QByteArray data = tcpSocketObj->readAll();
    qDebug() << "Received data:" << data;
    // 在這裡處理接收到的資料
}
