Qjson

Hi,
I am using the QJson for parsing. But I am stuck up with some issues. I have used the following code.

void CityBook ::getCityList(QUrl url)
{
//!connect(cityReply, SIGNAL(readyRead()),this, SLOT(httpReadyRead()));
cityGuideNetworkAccessManager = new QNetworkAccessManager(this);
connect(cityGuideNetworkAccessManager, SIGNAL(finished(QNetworkReply*)),
this, SLOT(httpReadyRead(QNetworkReply*)));
QNetworkRequest cityRequest(url);
cityGuideNetworkAccessManager->get(cityRequest);
}

void CityBook::httpReadyRead(QNetworkReply *reply)
{
QMessageBox::information(this, tr("HTTP"),
tr(reply->readAll()),QMessageBox::NoButton
);
QJson::Parser parser;
bool ok;
const QByteArray &resultbyte = reply->readAll();
qDebug() << resultbyte;
QVariant result1 = parser.parse(reply->readAll(), &ok);
qDebug() << result1;
QVariantList result=parser.parse(resultbyte,&ok).toList();
qDebug()<< result.size();
if (!ok)
{
qFatal("An error occurred during parsing");
exit (1);
}
qDebug() <<"error String"<< parser.errorString();
qDebug() <<"error" //! QVariantList entries = result["name"].toList();
foreach (QVariant city, result) {
QVariantMap names = city.toMap();
qDebug() << "\t-" << names.value("name");
}
}

The output is

Starting /Users/QT Developement/CityBook-build-desktop/CityBook.app/Contents/MacOS/CityBook...
""
QVariant(, )
0
error String ""
error 0

Please help me .. Where I have done mistake… Thanks is advance.

Code:

---

const QByteArray &resultbyte = reply->readAll();

---

What does this mean and do?

The meaning of the QByteArray is to provide the array of the bytes. Here The reply->readAll returns the byte array.

I know what a byte array is.

I want to read from you what this line exactly does. I know what it does, but I want you to see the mistakes.

Sorry. here i just assign the result to that particular variable.

What happens if you use

Code:

---

QByteArray resultbyte = reply->readAll();

---

?

I am also getting the same output.

Hi,

I can see the parsing the result. Just I made one chance in the code based on the following link http://stackoverflow.com/questions/3...ng-some-issues.

Thank u very much tbscope..

Thanks a lot.

Ohh, I didn't see the first readAll()
