QNetworkAccessManager help needed! Class problem...

[TCB13]

Hi,

I'm trying to download a page from a server to my QT program, but I've been searching ways to do it and they don't really work a lot. I'm not an expert in QT, so be kind

I ear some suggestions under StackOverflow about how to use QNetworkAccessManager. So here it is my codes so far working (almost) correctly.

http2.cpp

#include "http2.h"
 
http2::http2(QObject *parent) :
    QObject(parent)
{
    m_manager = new QNetworkAccessManager(this);
    connect(m_manager,SIGNAL(finished(QNetworkReply*)),this,SLOT(httpdown(QNetworkReply*)));
 
    QNetworkRequest request;
    request.setUrl(QUrl("http://localhost/test.php"));
    request.setRawHeader("User-Agent", "MyOwnBrowser 1.0");
 
    m_manager->get(request);
}
 
void http2::httpdown(QNetworkReply* result)
{
 
       QByteArray data= result->readAll();
       QString str(data);
 
       qDebug() <<  str;
 
}

#include "http2.h"

http2::http2(QObject *parent) :
    QObject(parent)
{
    m_manager = new QNetworkAccessManager(this);
    connect(m_manager,SIGNAL(finished(QNetworkReply*)),this,SLOT(httpdown(QNetworkReply*)));

    QNetworkRequest request;
    request.setUrl(QUrl("http://localhost/test.php"));
    request.setRawHeader("User-Agent", "MyOwnBrowser 1.0");

    m_manager->get(request);
}

void http2::httpdown(QNetworkReply* result)
{

       QByteArray data= result->readAll();
       QString str(data);

       qDebug() <<  str;

}

To copy to clipboard, switch view to plain text mode 

http2.h

#ifndef HTTP2_H
#define HTTP2_H
 
#include <QObject>
#include <QDebug>
#include <QtNetwork>
#include <QNetworkReply>
 
class http2 : public QObject
{
    Q_OBJECT
public:
    explicit http2(QObject *parent = 0);
 
signals:
 
public slots:
    void httpdown(QNetworkReply* result);
private:
    QNetworkAccessManager* m_manager;
 
};
 
#endif // HTTP2_H

#ifndef HTTP2_H
#define HTTP2_H

#include <QObject>
#include <QDebug>
#include <QtNetwork>
#include <QNetworkReply>

class http2 : public QObject
{
    Q_OBJECT
public:
    explicit http2(QObject *parent = 0);

signals:

public slots:
    void httpdown(QNetworkReply* result);
private:
    QNetworkAccessManager* m_manager;

};

#endif // HTTP2_H

To copy to clipboard, switch view to plain text mode 

Now if I call it directly under main.cpp like this:

main.cpp

#include <QtCore/QCoreApplication>
#include "tcpserver.h"
#include "http2.h"
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    http2 h; // --> Working!!
 
    tcpserver mServer;
 
    return a.exec();
}

#include <QtCore/QCoreApplication>
#include "tcpserver.h"
#include "http2.h"

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    http2 h; // --> Working!!

    tcpserver mServer;

    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

It works fine. However if I call it inside the tcpserver class like this:

tcpserver.cpp

#include "tcpserver.h"
#include "protocol.h"
#include "http2.h"
 
QTextStream in(stdin);
 
tcpserver::tcpserver(QObject *parent) :
    QObject(parent)
{
    server = new QTcpServer(this);
 
    [ ... Other Server Stuff ... ]
 
    http2 h; // --> Not Working :(
 
}

#include "tcpserver.h"
#include "protocol.h"
#include "http2.h"

QTextStream in(stdin);

tcpserver::tcpserver(QObject *parent) :
    QObject(parent)
{
    server = new QTcpServer(this);

    [ ... Other Server Stuff ... ]

    http2 h; // --> Not Working :(

}

To copy to clipboard, switch view to plain text mode 

The signal never happens... http2::httpdown(QNetworkReply* result) is never called, so I don't get the page contents.

What's wrong? :S

Thanks.
