Answer 1

1. Add QT += network in .pro project file

2. Include below libraries to your code:

   #include <QUrl>
   #include <QtNetwork/QNetworkAccessManager>
   #include <QtNetwork/QNetworkRequest>
   #include <QtNetwork/QNetworkReply>
   

3. At the end receive URL content via following code:

   QString url = "WEB_SERVICE_URL";
   QNetworkAccessManager manager;
   QNetworkReply *response = manager.get(QNetworkRequest(QUrl(url)));
   QEventLoop event;
   connect(response, SIGNAL(finished()), &event, SLOT(quit()));
   event.exec();
   QString content = response->readAll();
