router.get('/test', function(req, res, next) {
    sqlQuery("select * from userinfo", (data) => {
        let type2num = {}
        data.forEach(({ id, type, num }) => {
            if (type2num[type])
                type2num[type] += num
            else
                type2num[type] = num
        })
        res.send({
            code: "200",
            message: "查询成功",
            data,
            type2num,
        });
    });
});
