１：使用npm安装node-schedule模块
npm install node-schedule
（１）每隔５分钟执行一次：
var schedule = require('node-schedule');
var rule = new schedule.RecurrenceRule();
rule.minute = [0,5,10,15,20,25,30,35,40,45,50,55];
var j = schedule.scheduleJob(rule,function(){
console.log("执行任务："+new Date());
});
（２）上午８点到晚上２０点每隔５分钟执行一次：
var schedule = require('node-schedule');
var rule = new schedule.RecurrenceRule();
rule.hour = [8,9,10,11,12,13,14,15,16,17,18,19,20];
rule.minute = [0,5,10,15,20,25,30,35,40,45,50,55];
var j = schedule.scheduleJob(rule,function(){
console.log("执行任务："+new Date());
});
