How to create a json file using the rapidjson library from vector<string> data?

How can i create json file (string) from:

vector<string>m_paths

I have code:

 rapidjson::Document jsonfile;
    jsonfile.SetObject();
    rapidjson::Document::AllocatorType& jsonallocator = jsonfile.GetAllocator();


    std::vector<String>::iterator itm;
    rapidjson::Value paths(rapidjson::kArrayType);

    for(itm = m_paths.begin(); itm != m_paths.end(); ++itm)
    {
        //rapidjson::Value jValueConverting;
       // jValueConverting.SetString(GetLogRpl().c_str(), (rapidjson::SizeType)GetLogRpl().size(), jsonallocator);
    }

    jsonfile.AddMember("paths", paths, jsonallocator);


    rapidjson::StringBuffer jsonstring;
    rapidjson::Writer<rapidjson::StringBuffer> jsonwriter(jsonstring);
    jsonfile.Accept(jsonwriter);

    String fullJsonString = jsonstring.GetString();

    return fullJsonString;

I must use rapidjson library and don't know what i should do after creating allocator. Thanks for any help!

        StringBuffer sb;
        PrettyWriter writer(sb);
        writer.StartObject();
        writer.String(_T("paths"));
        writer.StartArray();
        std::vector<String>::iterator itm;
        for(itm = m_paths.begin(); itm != m_paths.end(); ++itm)
        {
            writer.String(*itm);
        }
        writer.EndArray();
        writer.EndObject();

        std::string fullJsonString = sb.GetString();
