auto convert from struct to qjsonobject and qjsonobject to struct

To convert from a struct to a QJsonObject, you can create a function that iterates over the struct's members and adds them to the QJsonObject. Here is an example:

#include <QJsonObject>
#include <QJsonDocument>
#include <QDebug>

struct MyStruct {
    int id;
    QString name;
    bool active;
};

QJsonObject structToJsonObject(const MyStruct& myStruct) {
    QJsonObject jsonObject;
    jsonObject["id"] = myStruct.id;
    jsonObject["name"] = myStruct.name;
    jsonObject["active"] = myStruct.active;
    return jsonObject;
}

int main() {
    MyStruct myStruct{1, "John", true};
    
    QJsonObject jsonObject = structToJsonObject(myStruct);
    
    QJsonDocument jsonDoc(jsonObject);
    qDebug() << jsonDoc.toJson();
    
    return 0;
}

To convert from a QJsonObject to a struct, you can create a function that extracts the values from the QJsonObject and assigns them to the struct members. Here is an example:

#include <QJsonObject>
#include <QJsonDocument>
#include <QDebug>

struct MyStruct {
    int id;
    QString name;
    bool active;
};

MyStruct jsonObjectToStruct(const QJsonObject& jsonObject) {
    MyStruct myStruct;
    myStruct.id = jsonObject["id"].toInt();
    myStruct.name = jsonObject["name"].toString();
    myStruct.active = jsonObject["active"].toBool();
    return myStruct;
}

int main() {
    QString jsonStr = R"({
        "id": 1,
        "name": "John",
        "active": true
    })";
    
    QJsonDocument jsonDoc = QJsonDocument::fromJson(jsonStr.toUtf8());
    QJsonObject jsonObject = jsonDoc.object();
    
    MyStruct myStruct = jsonObjectToStruct(jsonObject);
    
    qDebug() << "id:" << myStruct.id;
    qDebug() << "name:" << myStruct.name;
    qDebug() << "active:" << myStruct.active;
    
    return 0;
}

Note: These examples assume you have the necessary Qt libraries and headers included. Make sure to include the appropriate headers and link against the necessary libraries for your project
