QT获取本机的IP地址

现在经常的使用qt,现在需要解决使用qt如何获取本机的IP地址，经过摸索终于找到了方法。

QHostAddress CommonHelper::getLocalHostIP()
{
  QList<QHostAddress> AddressList = QNetworkInterface::allAddresses();
  QHostAddress result;
  foreach(QHostAddress address, AddressList){
      if(address.protocol() == QAbstractSocket::IPv4Protocol &&
         address != QHostAddress::Null &&
         address != QHostAddress::LocalHost){
          if (address.toString().contains("127.0.")){
            continue;
          }
          result = address;
          break;
      }
  }
  return result;
}
