iterate and retrieve nested object in JSON using rapidjson

Question

I am parsing a JSON structure which is similar as follows

{
    \"item1\" : \"value1\"
    \"item2\" : \"value2\"
    // ...
    \"itemn\" : {
          


        

Answer 1

void parseRecursive(std::string scope
                    , rapidjson::Value::ConstMemberIterator object
                    , std::unordered_map& values)
{
    if (scope.empty())
    {
        scope = object->name.GetString();
    }
    else
    {
        scope = scope + "::" + object->name.GetString();
    }
    auto inElement = scope + "::";

    if (object->value.IsObject())
    {
        for (auto it = object->value.MemberBegin(); it != object->value.MemberEnd(); ++it)
        {
            parseRecursive(scope, it, values);
        }
    }
    else if (object->value.IsDouble())
    {
        values.emplace(inElement, std::to_string(object->value.GetDouble()));
    }
    else if (object->value.IsInt())
    {
        values.emplace(inElement, std::to_string(object->value.GetInt()));
    }
    else
    {
        LOGW("Unsuported: " << inElement << object->name.GetString());
    }
}

And start with document: rapidjson::Document document;

for (auto it = document.MemberBegin(); it != document.MemberEnd(); ++it)
{
    parseRecursive("", it, _values);
}
