node.js中使用node-schedule实现定时任务实例
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:https://github.com/mattpat/node-schedule
npm install node-schedule
二、确定时间,例如:2012年11月21日,5:30
代码如下:
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();
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
代码如下:
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!');
});
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);
});
