Consuming a RESTful Web Service with C++ using QT libraries
After a long time I got a chance to work again with QT framework, Here are some of the findings about how to invoke RESTful webservices using QT. It's pretty easy really!! requirements g++ or compatible c++ compiler QT5 or later with QtNetwork module source main.cpp #include <QCoreApplication> #include <QtCore/QUrl> #include <QtNetwork/QNetworkRequest> #include <QtNetwork/QNetworkReply> #include <QJsonDocument> #include <QJsonObject> int main(int argc, char *argv[]) { QCoreApplication app(argc, argv); QEventLoop eventLoop; QNetworkAccessManager mgr; QObject::connect(&mgr, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit())); QNetworkRequest req( QUrl( QString("http://api.openweathermap.org/data/2.5/weather?q=colombo,lk") ) ); QNetworkReply *reply = mgr.get(req); eventLoop.exec(); if (reply->error() == QNetworkReply::NoError) { QString strReply = (QString)reply->r
