basic QNetworkAccessManager fails to send requestion - c++

Question

There is no error in my code though there is never any request packet hits my server. I run tcpdump port 80 and nothing ever crosses the wire, wireshark says the same.
//coreeng.h
#ifndef COREENG_H
#define COREENG_H
#include <QObject>
#include <QNetworkAccessManager>
class coreEng : public QObject
{
Q_OBJECT
public:
private slots:
public slots:
void connect();
void url();
void finishedSlot(QNetworkReply* reply);
private:
QNetworkAccessManager* nam;
};
#endif // COREENG_H
//coreengine.cpp
#include "coreeng.h"
#include <QNetworkAccessManager>
#include <QUrl>
#include <QNetworkRequest>
#include <QNetworkReply>
#include <QImageReader>
coreEng::coreEng(QObject *parent) :
QObject(parent)
{
}
explicit coreEng(QObject *parent = 0)
{
nam = new QNetworkAccessManager();
}
void coreEng::connect(){
QObject::connect(nam, SIGNAL(finished(QNetworkReply*)),
this, SLOT(finishedSlot(QNetworkReply*)));
}
void coreEng::url(){
QUrl url("http://www.myserver.com");
QNetworkReply* reply = nam->get(QNetworkRequest(url));
}
void coreEng::finishedSlot(QNetworkReply* reply){
QVariant statusCodeV = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute);
QVariant redirectionTargetUrl = reply->attribute(QNetworkRequest::RedirectionTargetAttribute);
if (reply->error() == QNetworkReply::NoError)
{
QImageReader imageReader(reply);
QImage pic = imageReader.read();
QByteArray bytes = reply->readAll(); // bytes
QString string(bytes); // string
}
else
{
}
delete reply();
}
//main.cpp
#include <QCoreApplication>
#include "coreeng.h"
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
coreEng mConnect;
mConnect.connect();
return a.exec();
}

Answer 1

You never call coreEng::url() so you never make a request.
I'm also not sure your constructors are correct. Why not just ditch the explicit constructor and create the QNetworkAccessManager in the default constructor?
