QNetworkAccessManager proper usage

Question

I want to POST some info to a php and GET the result from that php. My POST should look like: www.sample.com/test.php?un=user&pass=123345 I am trying all variants with no success:

m_NetworkAccessMNGR = new QNetworkAccessManager(this);
connect(m_NetworkAccessMNGR, SIGNAL(finished(QNetworkReply*)),
        this,SLOT(slotFinishRequest(QNetworkReply*)));
QNetworkRequest networkRequest;
networkRequest.setUrl(QUrl("http://www.sample.com/test.php?un=user&pass=123345"));

QNetworkReply *reply = m_NetworkAccessMNGR->get(networkRequest);

connect(reply, SIGNAL(readyRead()),
        this, SLOT(slotReadyRead()));
connect(reply, SIGNAL(finished()),
        this, SLOT(slotOnRequestCompleted()));
connect(reply, SIGNAL(error(QNetworkReply::NetworkError)),
        this, SLOT(slotOnRequestError(QNetworkReply::NetworkError)));
connect(reply, SIGNAL(sslErrors(QList<QSslError>)),
         this, SLOT(slotSslErrors(QList<QSslError>)));

The code doesn't execute any of these slots.
Does anybody has any ideea on what is the problem?
Thank you

Do you have an event loop somewhere else in your code?

If not, try this :

QEventLoop loop;

m_NetworkAccessMNGR = new QNetworkAccessManager(this);
QNetworkRequest networkRequest;
networkRequest.setUrl(QUrl("http://www.sample.com/test.php?un=user&pass=123345"));

QNetworkReply *reply = m_NetworkAccessMNGR->get(networkRequest);

connect(reply, SIGNAL(readyRead()),
        this, SLOT(slotReadyRead()));
connect(reply, SIGNAL(finished()),
        this, SLOT(slotOnRequestCompleted()));
connect(reply, SIGNAL(error(QNetworkReply::NetworkError)),
        this, SLOT(slotOnRequestError(QNetworkReply::NetworkError)));
connect(reply, SIGNAL(sslErrors(QList<QSslError>)),
        this, SLOT(slotSslErrors(QList<QSslError>)));

connect(reply, SIGNAL(finished()), &loop, SLOT(quit()));
loop.exec();

Does that work any better?
