How to get elements from json array

[Dy3zz]

I have the next JSON:

{"Number of people":3,"person":["Marian Marian","Badea Valentin","Ion Andrei"]}

response1 is my string with json format, and i want to print every person name. i tried jsonObject["person"][i] but it doesn't work. any help?

        QString qstr = QString::fromStdString(response1);
        QJsonDocument jsonResponse = QJsonDocument::fromJson(qstr.toUtf8());
        QJsonObject jsonObject = jsonResponse.object();
        int nr_rows=jsonObject["Number of people"].toInt();
        
        for(int i=0;i<nr_rows;i++){
            cout<<jsonObject["person"][i]; // how to print every element?

        }

@Dy3zz You need to use QJsonArray interface

QJsonArray a = jsonObject["person"].toArray();
for (int i = 0; i < a.size(); i++){
cout << a.at(i).toString();
}

@Dy3zz
Your array is a QJsonArray. I can't quite recall the syntax (not tested), but you'll want something like

jsonObject["person"].toArray()[i]

@Dy3zz You need to use QJsonArray interface

QJsonArray a = jsonObject["person"].toArray();
for (int i = 0; i < a.size(); i++){
cout << a.at(i).toString();
}

@Gojir4 said in How to get elements from json array:

QJsonArray a = jsonObject["person"].toArray();

I tried it but i have an error: calling toArray with incomplete return type

@Dy3zz You need to add #include <QJsonArray>

@Gojir4 Thanks it worked.
