QJson and Qt Symbian C++

Hi guys...
 I will show an example class to connect with json  parser.
Before compiling the class, you need to download the QJson library from this link http://qjson.sourceforge.net/get_it/


#include "login.h"

#include <QString>

#include <parser.h>

#include <QtNetwork>

#include <QDebug>

#include <QNetworkAccessManager>

#include <QVariant>

#include <QObject>

#include <QMessageBox>

#include "serializer.h"

QString StringList::changeMsisdnUrl;

changeMsisdnService::changeMsisdnService()

{

}

void changeMsisdnService::changeMSISDN(QString userName,QString password){

        QNetworkAccessManager* netAccManager = new QNetworkAccessManager;

        QNetworkRequest request(QUrl(http://www.your loginserviceurl));

 // the url's out put should be a json type. not an object.

        request.setHeader(QNetworkRequest::ContentTypeHeader, "application/json");

        QVariantMap msisdnDetails;

        msisdnDetails.insert("userName",userName);

        msisdnDetails.insert("password",password);

        QJson::Serializer serializer;

        QByteArray json = serializer.serialize(msisdnDetails);

        QNetworkReply *reply = netAccManager->post(request, json);

        QEventLoop loop;

        QObject::connect(reply,SIGNAL(finished()),&loop,SLOT(quit()));

        loop.exec();

        QByteArray bytes = reply->readAll();

               if (reply->error() == QNetworkReply::NoError)

               {

                   QJson::Parser parser;

                   bool ok;

                   QVariantMap result = parser.parse (bytes, &ok).toMap();

                   if (!ok) {

                     qFatal("An error occured during parsing");

                     exit (1);

                   }

                   status=result["status"].toString();

               }else{

               }

               if (status=="Success") {

                    // Your code

               } else {                  

                    // Your code

               }

}
