nodejs定時任務node-schedule

１：使用npm安裝node-schedule模塊

npm install node-schedule

（１）每隔５分鐘執行一次：

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("執行任務：" + new Date());
});

 （２）上午８點到晚上２０點每隔５分鐘執行一次：
 

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("執行任務：" + new Date());
});

 

２：如下內容參考：

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.

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.
 

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.
 

/* 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.
 

/* 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.
 

/* This runs at the 30th mintue of every hour. */

cron.scheduleJob('30 * * * * *',function(){

    console.log('This runs at the 30th mintue of every hour.');

});
