Answer 2

引用北上广的醋坛子的回答：
throw err;
}else{
connection.query("SELECT * FROM cash_daily_coin WHERE uid_fk="+results[0].uid+"",
function selectCb(err, daily, fields) {
if (err) {
throw err;
}else{
var datas = resultss[0];
datas.deviceid = deviceid;
datas.todaycoin = daily[0].todaycoin;
req.session["user"] = datas;
res.jsonp(datas);//返回JSON
}
}
);

里面写一个回掉函数，
