Qt parsing JSON using QJsonDocument, QJsonObject, QJsonArray

Question

I'm using Qt5. I am trying to obtain values from a json object. Here is what the json object looks like that I am trying to get data from:

{     "success": true,     "properties": [         {             "ID": 1001,             "PropertyName": "McDonalds",             "key": "00112233445566778899aabbccddeeff"         },         {             "ID": 1002,             "PropertyName": "Burger King",             "key": "10112233445566778899aabbccddeeff"         },         {             "ID": 1003,             "PropertyName": "Taco Bell",             "key": "20112233445566778899aabbccddeeff"         }     ] } 

How can I create three arrays that contain properties[x].ID, properties[x].PropertyName, and properties[x].key in Qt?

Edit:

Using QScriptEngine I tried this:

QString data = (QString)reply->readAll();  QScriptEngine engine;  QScriptValue result = engine.evaluate(data);  qDebug() << result.toString(); 

Debug is saying "SyntaxError: Parse error"

I figured it out:

QStringList propertyNames; QStringList propertyKeys; QString strReply = (QString)reply->readAll(); QJsonDocument jsonResponse = QJsonDocument::fromJson(strReply.toUtf8()); QJsonObject jsonObject = jsonResponse.object(); QJsonArray jsonArray = jsonObject["properties"].toArray();  foreach (const QJsonValue & value, jsonArray) {     QJsonObject obj = value.toObject();     propertyNames.append(obj["PropertyName"].toString());     propertyKeys.append(obj["key"].toString()); }
