Question

我只是在寻找有关json答案的帮助。

当我在postgres数据库上使用查询时，得到以下结果：

select sum(total_value), CAST(date_start AS DATE) 
  from result 
 where DATE(date_start) BETWEEN '2019-07-11' AND '2019-07-18' 
 group by CAST(date_start AS DATE) 
 order by CAST(date_start AS DATE);

"16.81" "2019-07-11"
"15.42" "2019-07-12"
"40.08" "2019-07-15"
"11.45" "2019-07-16"
"91.52" "2019-07-17"
"25.34" "2019-07-18"

但是，如果我尝试使用pg模块的nodejs：

app.get('/getData', function(req, res) {
  var date = new Date()
  var lastWeek = new Date();
  lastWeek.setDate(lastWeek.getDate()-7)
  date1 = date.getFullYear() +"-"+ (date.getMonth()+1) +"-"+ date.getDate()
  date2 = lastWeek.getFullYear() +"-"+ (lastWeek.getMonth()+1) +"-"+ lastWeek.getDate()
  console.log(date1, date2)
  pool.query('select sum(total_value), CAST(date_start AS DATE) from result where DATE(date_start) BETWEEN '2019-07-11' AND '2019-07-18' GROUP BY CAST(date_start AS DATE) ORDER BY CAST(date_start AS DATE)', 
  (error, results) => {
    if (error) {
      throw error
    }
    res.status(200).json(results.rows)
  })
})

我得到了这个JSON答案：

[{"sum":"16.81","date_start":"2019-07-10T22:00:00.000Z"}, 
{"sum":"15.42","date_start":"2019-07-11T22:00:00.000Z"}, 
{"sum":"40.08","date_start":"2019-07-14T22:00:00.000Z"}, 
{"sum":"11.45","date_start":"2019-07-15T22:00:00.000Z"}, 
{"sum":"91.52","date_start":"2019-07-16T22:00:00.000Z"}, 
{"sum":"25.34","date_start":"2019-07-17T22:00:00.000Z"}]

为什么我的日子不一样？
