node.js定时事务node-schedule

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。

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!');
});
