1.获取计算机名称:

/* * 名称:get_localmachine_name * 功能:获取本机机器名称 * 参数:no * 返回:QString */QString CafesClient::get_localmachine_name(){    QString machineName     = QHostInfo::localHostName();    return machineName;}

2.获取本机IP地址

/* * 名称:get_localmachine_ip * 功能:获取本机的IP地址 * 参数:no * 返回:QString */QString CafesClient::get_localmachine_ip(){    QString ipAddress;    QList
     
       ipAddressesList = QNetworkInterface::allAddresses();    // use the first non-localhost IPv4 address    for (int i = 0; i < ipAddressesList.size(); ++i) {        if (ipAddressesList.at(i) != QHostAddress::LocalHost &&            ipAddressesList.at(i).toIPv4Address()) {            ipAddress = ipAddressesList.at(i).toString();            break;        }    }    // if we did not find one, use IPv4 localhost    if (ipAddress.isEmpty())        ipAddress = QHostAddress(QHostAddress::LocalHost).toString();    return ipAddress;}
     

3.获取本机网络连接名、MAC地址

/* * 名称:get_localmachine_mac * 功能:获取本机的MAC地址 * 参数:no * 返回:void */QString CafesClient::get_localmachine_mac(){    QList
     
       nets       = QNetworkInterface::allInterfaces();    int i = 0;    foreach(QNetworkInterface ni,nets)    {        i++;        qDebug()<
      <
       
        <
        
         <
        
       
     

4.获取本机子网掩码、广播地址

在上个函数的环境下QList
     
       entryList =interface.addressEntries();    10.      //获取IP地址条目列表，每个条目中包含一个IP地址，一个子网掩码和一个广播地址    11.         foreach(QNetworkAddressEntry entry,entryList)    12.         {
   //遍历每一个IP地址条目    13.             qDebug()<<”IP Address: “<
