如何使用Kue每个星期四安排一次工作? [英] How to schedule a job once every Thursday using Kue?

问题描述

使用 Kue ，我该如何安排每个星期四执行一次作业? Kue自述文件提到我可以延迟Job，但是在特定时间重复执行Job怎么办?

Using Kue, how do I schedule a job to be executed once every Thursday? The Kue readme mentions that I can delay a Job, but what about repeatedly executing the Job at a specific time?

我可以通过Cron来做我想做的事，但是我喜欢Kue的功能.

I can do what I want with a cron job, but I like Kue's features.

我想要的是在星期四的任何时候处理一次作业，但是只能处理一次.

What I want is to process a Job once anytime on Thursday, but only once.

推荐答案

我有一个类似的问题，基本上我提出了以下问题.如果其他人有不同的解决方案，我很乐意看到其他一些想法.

I had a similar question and I basically came up with the following. If anyone else has a different solution I would love to see some other ideas.

var jobQueue = kue.createQueue();

// Define job processor
jobQueue.process('thursday-jobs', function (job, done) {

  var milisecondsTillThurs = // TODO: Get the time until next thursday.  For this I used moment.js

  // do this job again next Thursday
  jobQueue.create('thursday-jobs').delay(milisecondsTillThurs).save();

  // For Example purpose this job waits then calls done
  setTimeout(function () {
      done();
  }, 10000);


});

// Use some initialization code to check if the job exists yet, and create it otherwise
kue.Job.rangeByType('thursday-jobs','delayed', 0, 10, '', function (err, jobs) {
    if (err) {return handleErr(err);}
    if (!jobs.length) {
        jobQueue.create('thursday-jobs').save();
    }
    // Start checking for delayed jobs.  This defaults to checking every 5 seconds
    jobQueue.promote();
});

Kue 的文档很少，但是源代码的注释很好并且易于阅读

Kue has minimal documentation, but the source is well commented and easy to read
