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。
github地址:
安装
npm install node-schedule
1.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 j.cancel();
2.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!'); });
3.一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!'); });
