1:使用npm安装node-schedule模块

(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];
