How to parse Json array give below

[Vikram.Saralaya]

QJsonDocument jsonResponse = QJsonDocument::fromJson(strReply.toUtf8());
QJsonObject jsonObject = jsonResponse.object();
QJsonValue value = jsonObject.value("enclosures");
QJsonArray array = value.toArray();

This code should work fine.

qDebug() << array;

qDebug() << array;

To copy to clipboard, switch view to plain text mode 

gives the output as expected:

QJsonArray([{"data":{"enclosure_id":"0","enclosure_model":"MD1220 ","no_of_fans":"4","no_of_power_supplies":"2","no_of_slots":"24","product_revision_level":"1.01","temp_sensor_count":"4","vendor":"DELL "}}])

QJsonArray([{"data":{"enclosure_id":"0","enclosure_model":"MD1220 ","no_of_fans":"4","no_of_power_supplies":"2","no_of_slots":"24","product_revision_level":"1.01","temp_sensor_count":"4","vendor":"DELL "}}])

Make sure your file/json is not corrupt. You can easily do that by adding a qDebug() statement after each line and see what you have then..

Edit:
Apparently I see there is a problem with how you read from this array in your first post:

Working version:

foreach (const QJsonValue & val, array)
{
    QJsonObject dataObj = val.toObject().value("data").toObject();
    qDebug() << dataObj.value("enclosure_id").toString();
}

foreach (const QJsonValue & val, array)
{
    QJsonObject dataObj = val.toObject().value("data").toObject();
    qDebug() << dataObj.value("enclosure_id").toString();
}

To copy to clipboard, switch view to plain text mode 

PS: If you want to store enclosure_id as integer remove the double quotes.
