How does Node.js get the value of the out parameter after executing the mysql stored procedure with the out parameter?

how does Node.js get the value of the out parameter after executing the mysql stored procedure with the out parameter? I want to get the values of the two parameters _ totalcount,_pagecount, but the return value is not in rows. The code is as follows:

        ssql = "call sp_MvcCommonDataSource(?,?,?,?,?,?,?,@_totalcount,@_pagecount,@ss)";
        sqlParam=["*","article","","id",pageindex,pagesize,""];
        connection.query(sql,sqlParam, function (err, rows, fields) {
            if (err) {
                throw err;
                console.log(":" + err);
            }
            else {
                json = JSON.stringify(rows)
                console.log(":" + json);
            
              //  res.send(json);
            }
