C++ QT获取本机公网IP和IP所在地

void getIPAndAddress()
{
  QNetworkAccessManager manager_;
  QNetworkReply *reply = manager_.get(QNetworkRequest(QUrl("http://whois.pconline.com.cn/ipJson.jsp?json=true")));
  QEventLoop loop;
  QObject::connect(reply, &QNetworkReply::finished, &loop, &QEventLoop::quit);
  loop.exec();
  QString data = QString::fromLocal8Bit(reply->readAll());
  QJsonDocument jsonDocument = QJsonDocument::fromJson(data.toUtf8());
  QJsonObject jsonObject = jsonDocument.object();
  QString ip = jsonObject.value("ip").toString();
  QString address = jsonObject.value("addr").toString().toUtf8();
  qDebug() << "ip:" << ip ;
  qDebug() << "loaction:"<< address ;
  reply->deleteLater();
