有的时候需要根据业务需要,晚上凌晨以后执行某些操作的时候,这个可能会有所帮助,我最近正在研究这个,欢迎共同探讨。

一、安装
npm install node-schedule
二、确定时间,例如:2012年11月21日,5:30
var schedule = require('node-schedule'); var date = new Date(2012, 11, 21, 5, 30, 0); var j = schedule.scheduleJob(date, function(){ console.log('The world is going to end today.'); }); 取消预设计划 [code] j.cancel();
三、每小时的固定分钟,例如:每个小时的42分钟
var schedule = require('node-schedule'); var rule = new schedule.RecurrenceRule(); rule.minute = 42; var j = schedule.scheduleJob(rule, function(){ console.log('The answer to life, the universe, and everything!'); });
四、.一个星期中的某些天的某个时刻,例如:每周四,周五,周六,周天的17点
var rule = new schedule.RecurrenceRule(); rule.dayOfWeek = [0, new schedule.Range(4, 6)]; rule.hour = 17; rule.minute = 0; var j = schedule.scheduleJob(rule, function(){ console.log('Today is recognized by Rebecca Black!'); });
五、每秒执行
var rule = new schedule.RecurrenceRule(); var times = []; for(var i=1; i<60; i++){ times.push(i); } rule.second = times; var c=0; var j = schedule.scheduleJob(rule, function(){ c++; console.log(c); });
node.js中使用node-schedule实现定时任务实例
