c++ - 如何使用 rapidjson 库从 vector 数据创建 json 文件？

Question

我如何创建 json 文件(字符串):

vector<string>m_paths

我有代码:

 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;

我必须使用 rapidjson 库并且不知道在创建分配器后我应该做什么。感谢您的帮助!

        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();
