获取时间戳,注意在微信小程序按照时间戳对数据库内容排序时,orderBy的第一个参数类型为Number
var timeStamp = Date.parse(new Date());
timeStamp = timeStamp / 1000;
const cloud = require('wx-server-sdk')
cloud.init()
exports.main = async (event, context) => {
var value={}
console.log(value)
const db=cloud.database()
await db.collection('article')
.orderBy("timestamp",'desc')
.get()
.then(res=>{
console.log(res.data)
value.data=res.data
console.log(value)
})
return value
}
获取当前日期、时间并连接成如2022-04-19 19:40:10样式
var blank=""
var myDate = new Date();
var year=myDate.getFullYear();
var month=(myDate.getMonth() + 1 < 10 ? '0' + (myDate.getMonth() + 1) : myDate.getMonth() + 1);
var date=myDate.getDate() < 10 ? '0' + myDate.getDate() : myDate.getDate();
var hour=myDate.getHours() < 10 ? '0' + myDate.getHours() : myDate.getHours();
var min=myDate.getMinutes() < 10 ? '0' + myDate.getMinutes() : myDate.getMinutes();
var sec=myDate.getSeconds() < 10 ? '0' + myDate.getSeconds() : myDate.getSeconds();
var myTime=blank.concat(year,"-",month,"-",date," ",hour,":",min,":",sec);
