１：使用npm安裝node-schedule模塊

npm install node-schedule

（１）每隔５分鐘執(zhí)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("執(zhí)行任務(wù)："+new Date()); });

?（２）上午８點到晚上２０點每隔５分鐘執(zhí)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("執(zhí)行任務(wù)："+new Date()); });

?

２：以下內(nèi)容參考：

http://www.codexpedia.com/javascript/nodejs-cron-schedule-examples/

Using the node-schedule to schedule a job to run at a specific time on a specific date. As the first example, the node-schedule module is imported and save it in the variable cron. In the following examle, the require statement will be ommitted and this variable cron will be used.

1 2 3 4 5 6

var cron = require('node-schedule'); /* run the job at 18:55:30 on Dec. 14 2018*/ var date = new Date(2018, 11, 14, 18, 56, 30); cron.scheduleJob(date, function(){ ????console.log(new Date(), "The world is going to end today.");??? });

?

Schedule a recurring job using the RecurrenceRule, example 1.

1 2 3 4 5

var rule = new cron.RecurrenceRule(); rule.second = 30; cron.scheduleJob(rule, function(){ ????console.log(new Date(), 'The 30th second of the minute.'); });

?

Schedule a recurring job using the RecurrenceRule, example 2.

1 2 3 4 5 6 7 8

/* This runs at 3:10AM every Friday, Saturday and Sunday. */ var rule2 = new cron.RecurrenceRule(); rule2.dayOfWeek = [5,6,0]; rule2.hour = 3; rule2.minute = 10; cron.scheduleJob(rule2, function(){ ????console.log('This runs at 3:10AM every Friday, Saturday and Sunday.'); });

?

Specify the schedule as an object literal.

1 2 3 4

/* This runs at 2:30AM on every Sunday */ cron.scheduleJob({hour: 2, minute: 30, dayOfWeek: 0}, function(){ ????console.log('This runs at 2:30AM on every Sunday'); });

?

Specify the schedule in unix cron syntax.

1 2 3 4

/* This runs at the 30th mintue of every hour. */ cron.scheduleJob('30 * * * * *', function(){ ????console.log('This runs at the 30th mintue of every hour.'); });
