Qt获取IP地址、用户名、机器名、MAC地址

获取ip地址

 

[cpp] view plaincopy

1. // 获得ip地址  QString USBMainUI::getIpAdress() 
    {      
       QString localIPAddress = "";       
       QListlistAddress = QNetworkInterface::allAddresses();       
       for(int j = 0; j < listAddress.size(); j++)
       {           
           if(!listAddress.at(j).isNull() &&listAddress.at(j).protocol() ==  QAbstractSocket::IPv4Protocol&& listAddress.at(j) != QHostAddress::LocalHost)            
           {              
                 localIPAddress = listAddress.at(j).toString();               
                 return localIPAddress;           
           }       
       }           
       return localIPAddress;  
   }  

    

获取用户名

 

 

[cpp] view plaincopy

1. // 获得用户名  QString USBMainUI::getUserName()  
   {      
       QString userName = QDesktopServices::storageLocation(QDesktopServices::HomeLocation);      
       userName = userName.section("/", -1, -1);     
        return userName;  
   }  

    

 

 

获取机器名字

 

[cpp] view plaincopy

// 获得机器名字  QString USBMainUI::getMachineName()  
{      
    QString localHostName = QHostInfo::localHostName();      
    return localHostName;  
}  

 

获取MAC地址

1. // 获得MAC地址  
   QString USBMainUI::getMACAdress()  
   {  
       QList  NetList;    //网卡链表  
       int NetCount = 0;           //网卡个数  
       int Neti = 0;  
       QNetworkInterface thisNet;      //所要使用的网卡  
       NetList = QNetworkInterface::allInterfaces();//获取所有网卡信息  
       NetCount = NetList.count();         //统计网卡个数  
       for(Neti = 0;Neti < NetCount; Neti++){   //遍历所有网卡  
               if(NetList[Neti].isValid()){    //判断该网卡是否是合法  
                       thisNet = NetList[Neti];    //将该网卡置为当前网卡  
                   break;  
               }  
       }  
       return ( thisNet.hardwareAddress() );   //获取该网卡的MAC  
   }
