node.js使用node-schedule实现定时任务
github地址：https://github.com/mattpat/node-schedule
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：
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);
});
