Not getting any response from post request in form url encoded format

[ndiwan]

Hi SGaist,

Do I need to do like this:

void HttpWorker::onPostAnswer(QNetworkReply* reply)
{
int statusCode = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute).toInt();
if(statusCode == 200)
{
const QJsonDocument response = QJsonDocument::fromJson(reply->readAll());
const QJsonObject response_json = QJsonDocument::fromVariant(response.object().value("smsession").toVariant()).object();
}
}

void HttpWorker::GetSiteminderToken()
{
QNetworkReply* reply;
QNetworkRequest request(QUrl("https://xxtest.employees.www.uprr.com/admin/login.fcc"));
request.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");

QUrlQuery postArray;
postArray.addQueryItem("TARGET" , "https://xxtest.employees.www.uprr.com/hmp/alert-handler/1.0/secure/jas/fetch-session-cookie");
postArray.addQueryItem("USER" , "abcd1234");
postArray.addQueryItem("PASSWORD" , "rfte123");

QNetworkAccessManager manager = new QNetworkAccessManager(this);
connect(manager, SIGNAL(finished(QNetworkReply)),
SLOT(onPostAnswer(QNetworkReply*)));
reply = manager->post(request, postArray.toString(QUrl::FullyEncoded).toUtf8());

}

But Still status code is 0. It should be 200.

Thanks

I don't know, but maybe you should slot onto QNetworkReply::errorOccurred signal?

[SGaist]

Please use coding tags around your code to make it readable (the </> button on the toolbar).

That said the connect statement looks wrong since you have once a pointer for the signal and the other an object for the slot.

void HttpWorker::postFinished(QNetworkReply* rep)
{
QByteArray bts = rep->readAll();
QString str = QString::fromUtf8(bts);
qDebug().noquote() << "Reply:"<<str;
rep->deleteLater();
}

QString HttpWorker::GetSiteminderToken()
{

QNetworkReply* reply;
QNetworkRequest request(QUrl("https://xxtest.employees.www.uprr.com/admin/login.fcc"));
request.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");

QUrlQuery postArray;
postArray.addQueryItem("TARGET" , "https://xxtest.emp->oyees.www.uprr.com/hmp/alert-handler/1.0/secure/jas/fetch-session-cookie");
postArray.addQueryItem("USER" , "abcd1234");
postArray.addQueryItem("PASSWORD" , "frtg4567");
QNetworkAccessManager *manager = new QNetworkAccessManager(this);
connect(manager,SIGNAL(finished(QNetworkReply*)),this,SLOT(postFinished(QNetworkReply*)));
manager->post(request, postArray.toString(QUrl::FullyEncoded).toUtf8());

}

Still getting str as "" .

Thanks

This may be helpful. Try to check your return in postFinished().
m_reply = m_networkAccessManager.post( request, byte_array );
if ( nullptr != m_reply ) {
    if ( m_reply->isRunning() ) {
        connect( m_reply, &QNetworkReply::finished,
                 this,    &MyClass::postFinished );
    }
    else { /* may be finished immediately*/
        postFinished();
    }
}

Sorry that didnt work.

@ndiwan
Put a breakpoint on entry to onPostAnswer(). Use the watch window to have a dig around in *reply to see what you can see there! Anything interesting? You say returned state code is 0, which I don't think is a code HTTP would return at all. I did also suggest you verify you do not get any error.

[JoeCFD]

print out the error message while m_reply has to be global in the class.
void MyClass::postFinished()
{
if ( nullptr != m_reply ) {
if ( QNetworkReply::NoError == m_reply->error() ) { /* update is successful */
}

[JoeCFD]

Try your QUrl with the following format:
http://user:password@domain.com/

HI All,

If you notice the body of my request, it has a target url that will return a cookie. That cookie should append to the final post request.
So is there any other way to handle cookies ?

Thanks
