QT 获取本地IP MAC地址 外网IP 位置信息 连网状态 操作系统信息

Qter

在pro文件加了一行
QT += network

1. #include <QHostAddress>
   
2. #include <QNetworkInterface>
   
3. QString MainWindow::gethostIp()
   
4. {
   
5.     QString strIpAddress;
   
6.     QList<QHostAddress> ipAddressesList = QNetworkInterface::allAddresses();

8.     int nListSize = ipAddressesList.size();
   
9.     for (int i = 0; i < nListSize; ++i)
   
10.     {

连网状态

1. bool MainWindow::IPLive(QString ip, int port)
   
2. {
   
3.     QTcpSocket tcpClient;
   
4.     tcpClient.abort();
   
5.     tcpClient.connectToHost(ip, port);
   
6.     //100毫秒没有连接上则判断不在线
   
7.     return tcpClient.waitForConnected(100);
   
8. }
   
9. 调用  判断百度 80端口是否连通
   
10. qDebug() << IPLive("202.108.22.5", 80);
