Qt : Accessing Secure Objects using session-id from a server - c++

Question

I am working on a Qt application in which I would like to retrieve objects which are tagged #Secured in the Spring-MVC based web-application. I have written the code on the server side for REST authentication and if I use the 'curl' tool, then I am able to access secure services on the server. I would like to know if there is anyway I can replicate the way I am accessing secured services in a QT application. Any help would be nice. Thanks a lot.
curl code :
curl -i -X POST -d j_username=email#email.de -d j_password=password -c /home/username/cookies.txt http://localhost:8080/j_spring_security_check
And for using the session-id to access secure services, I do :
curl -i --header "Accept:application/json" -X GET -b /home/cookies.txt http://localhost:8080/secure_service_method
How can I achieve the same thing in QT. Any help would be nice. Please note, I am not that of an expert in Qt, so please be patient. Thanks a lot.

Converting my comments into this answer:
Judging from your curl command you probably just need to send a POST request and handle the cookies using Qt . Qt provides everything necessary to accomplish this task, have a look at QNetworkAccessManager::post and QNetworkAccessManager::setCookieJar.
The basic steps you need to implement will look like this:
1.) Setup:
QNetworkAccessManager* manager = new QNetworkAccessManager(this);
manager->setCookieJar(new QNetworkCookieJar(manager));
connect(manager,SIGNAL(finished(QNetworkReply*)),this,SLOT(replyFinished(QNetworkReply*)));
2.) Request the cookie
QNetworkRequest request;
request.setUrl(QUrl("http://localhost:8080/j_spring_security_check"));
QByteArray postData;
postData.append("j_username=email#email.de&j_password=password");
manager->post(request,postData);
3.) Use the manager object which then has the cookie to request the protected files.
