          goodsInfo: res.data,
          changePrice: res.data.current_price + 1
        })
        //根据发布者id去用户表中查询商品发布者信息
        wx.cloud.database().collection('userInfo').doc(res.data.publisher_id).get({
          success: (res) => {
            this.setData({
              publisher: res.data
            })
          }
        })
      }
    })
  },
  //底部加减价格

  //竞拍者出价

    let price = this.data.changePrice

    let userInfo = wx.getStorageSync('userInfo')
    //获取出价时间
    let nowTime = new Date().getTime()

    var util = require("../../util/time_transform.js")
    let timeFormat = util.js_date_time(nowTime)
    //弹窗确认
    wx.showModal({
      title: '确认出价',

          wx.showLoading({
            title: '正在出价...',
          })
          //保存竞拍记录到数据库
          wx.cloud.database().collection('goodsAuctionRecord').add({
              data: {
                goodsID: goods_id,
                userInfo: userInfo,
                putPrice: price,
                auctionTime: nowTime,
                auctionTimeFormat: timeFormat
              },
              success: res => {}
            }),
            //更新当前价
            wx.cloud.database().collection('goods').doc(goods_id).update({
              data: {
                current_price: price
              }
            })
          let _this = this
          setTimeout(function () {
            wx.hideLoading({
              success: (res) => {
                //刷新页面数据
                _this.onShow()
              }
            })
          }, 1000)
        } else {
          console.log('取消')
        }
      }
    })
  },
  //获取商品用户竞拍记录
  getAuctionRecord() {
    wx.cloud.database().collection('goodsAuctionRecord').where({
      goodsID: goods_id
    }).get({
      success: (res) => {
        this.setData({
          auctionRecord: res.data
        })
      }
    })
  },
  //获取竞拍结束时间，并计算倒计时
  countdown(goodsId) {
    wx.cloud.database().collection('goods').doc(goodsId).get({
      success: res => {
        //取出竞拍结束时间，精确到秒
        let auctionEndtime = res.data.end_time
        console.log(res)
        //获取当前系统时间,只精确到秒
        var nowTime = new Date().getTime() / 1000
        //剩余时间总的秒数
        var totalSecond = Math.floor(auctionEndtime - nowTime)
        console.log('剩余秒数', totalSecond)
        //计算倒计时
        this.doCountdown(totalSecond)
      }
    })
  },
  //计算商品倒计时
  doCountdown(totalSecond) {
    let _this = this
    //每隔一秒执行一次代码
    myTime = setInterval(function () {
      //如果竞拍已经结束
      if (totalSecond < 0) {
        _this.setData({
          clock: '已经截止'
        })
        clearInterval(myTime)
        return
      } else {
        //执行计算
        var time = _this.formatTime(totalSecond)
        _this.setData({
          clock: '剩余' + time
        })
      }
      totalSecond--;
    }, 1000)
  },
  //倒计时时间格式化
  formatTime(totalSecond) {
    //剩余天数
    var day = Math.floor(totalSecond / 3600 / 24)
    //n天后剩余小时数
    var hour = Math.floor(totalSecond / 3600 % 24)
    //n天n小时后剩余分钟数
    var min = Math.floor(totalSecond / 60 % 60)
    //n天n小时n分钟后剩余秒数
    var sec = Math.floor(totalSecond % 60)
    return day + "天" + hour + "小时" + min + "分" + sec + "秒"
  }
})

4、时间转化js代码

在util 下面新建一个time_transform.js文件

//时间戳转换成日期时间，传入时间精确到毫秒
function js_date_time(unixtime) {
  var date = new Date(unixtime)
  var y = date.getFullYear();
  var m = date.getMonth() + 1;
  m = m < 10 ? ('0' + m) : m;
  var d = date.getDate();
  d = d < 10 ? ('0' + d) : d;
  var h = date.getHours();
  h = h < 10 ? ('0' + h) : h;
  var minute = date.getMinutes();
  var second = date.getSeconds();
  minute = minute < 10 ? ('0' + minute) : minute;
  second = second < 10 ? ('0' + second) : second;
  return y + '-' + m + '-' + d + ' ' + h + ':' + minute + ':' + second;//年月日时分秒
  // return y + '-' + m + '-' + d + ' ' + h + ':' + minute;
  // return y + '-' + m + '-' + d;
}
module.exports = {
  js_date_time: js_date_time
}
