Foreach Through QJsonObject to get Key/Value Pair - c++

Question

I am wondering how I would foreach through a QJsonObject to get the key/value pairs in C++? So far, I am only able to get the value.
//main.cpp
QFile file(":/geoip.json");
file.open(QIODevice::ReadOnly);
QByteArray rawData = file.readAll();
file.close();
QJsonDocument doc(QJsonDocument::fromJson(rawData));
QJsonObject json = doc.object();
foreach(const QJsonValue &value, json) {
QJsonObject obj = value.toObject();
qDebug() << value;
}
//geoip.json
{
"Afghanistan": "58.147.159.255",
"Albania": "31.22.63.255",
"Algeria": "105.235.143.255",
"American Samoa": "202.70.115.241",
"Andorra": "109.111.127.255",
"Angola": "105.175.255.255",
"Anguilla": "208.66.50.44",
"Antarctica": "46.36.195.10"
}

John already gave the answer. Using keys() a complete working solution would be:
#include <QCoreApplication>
#include <QFile>
#include <QByteArray>
#include <QJsonDocument>
#include <QJsonObject>
#include <QJsonValue>
#include <QDebug>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
//main.cpp
QFile file("path/to/geoip.json");
file.open(QIODevice::ReadOnly);
QByteArray rawData = file.readAll();
file.close();
QJsonDocument doc(QJsonDocument::fromJson(rawData));
QJsonObject json = doc.object();
foreach(const QString& key, json.keys()) {
QJsonValue value = json.value(key);
qDebug() << "Key = " << key << ", Value = " << value.toString();
}
return a.exec();
}

I know this post is old but to answer Nuclear
With the method proposed by Twisq it is possible to browse a JSON by obtaining the keys and values ​​without problem.
But you are talking about iterating a JSON...?
With "QJsonObject::const_iterator" objects it is possible with the code below:
#include<QJsonDocument>
#include<QJsonObject>
#include<QFile>
int main (int nbArg, char* listArg[])
{
QFile file("my_file.json");
file.open(QIODevice::ReadOnly);
QByteArray rawData = file.readAll();
file.close();
QJsonDocument doc(QJsonDocument::fromJson(rawData));
QJsonObject myJson = doc.object();
QJsonObject::const_iterator myIterator = myJson.constBegin();
QJsonObject::const_iterator myIteratorEnd = myJson.constEnd();
do
{
qDebug() << myIterator.key();
qDebug() << myIterator.value();
myIterator++;
}
while(myIterator!=myIteratorEnd);
}
