//tuple
std::tuple<int, int, int, int, QString> Thorface::getUserInfoToJudgeOpendoor(QString strUserCode)
{
int iunpaidOrderList = 0;
int iunhandledOrderList = 0;
int istatus = 0;
int ibindFace = 0;
QString strUserName = "";
    return std::make_tuple(iunpaidOrderList, iunhandledOrderList, istatus, ibindFace, strUserName);
}

//tie解析
                int iunpaidOrderList = 0;
                int iunhandledOrderList = 0;
                int istatus = -1;
                int ibindFace = -1;
                QString strUserName = "";
                std::tie(iunpaidOrderList, iunhandledOrderList, istatus, ibindFace, strUserName) = getUserInfoToJudgeOpendoor(strName);
