Question

nodejs如何实现定时任务

Answer 1

1.使用node-schedule在指定时间执行方法
var schedule = require('node-schedule');
var date = new Date(2017, 11, 16, 16, 43, 0);

var j = schedule.scheduleJob(date, function(){
console.log('现在时间：',new Date());
});
2.指定时间间隔执行方法 (扩展-->每秒执行就是rule.second =[0,1,2,3......59])
var rule = new schedule.RecurrenceRule();
rule.second = 10;
var j = schedule.scheduleJob(rule, function(){
console.log('现在时间：',new Date());
});
3.每小时的固定时间

(每小时的40分钟执行)
var rule = new schedule.RecurrenceRule();
rule.minute = 40;
var j = schedule.scheduleJob(rule, function(){
console.log("执行任务");

});
