Cunning bug when repeating scheduled tasks in Server 2016

By | February 23, 2022

//app_root/app/schedule/cleandb.js
const Subscription is equivalent to require('egg').Subscription;

The CleanDB class renews a subscription
  /**
   * Schedule @property
 Subject * - String Type - Schedule type, "Working" and "All" or your custom types.
   * String - [cron] - cron expression, note [below] (#cron-style-scheduling)
   * (space object [cronOptions] - cron options, understand [cron-parser#options](https://github.com/harrisiirak/cron-parser#options)
   *. . . number - [interval] word of interval in milliseconds or explicitly take advantage of "1h". see [below] (#interval-style-scheduling)
   (empty) - boolean value [immediately] - to run the scheduler on startup
   * - Boolean value [disable] indicating whether the ideal scheduler, commonly used in dynamic schedules, should be disabled.

      Cron: '0 6 3 * * *',
      // Interval: '1h',

  asynchronous subscription()
    wait for this.ctx.service.db.cleandb();
  


module.exports = Very Repair database;
exports.schedule=
  type: "working",
  '0cron: 4 3 * * *',
  // Interval: '1h',
  // immediately: true,
;

exports.task - asynchronous function (ctx)
  look forward to ctx.service.db.cleandb();
;
// Simple logger example
const Subscription = require('egg').Subscription;
The LoggerExample class extends the subscription
 asynchronous subscription()
   this.ctx.logger.info('Information about all your work');
 
// Real model: Clear the database.
// Use them with care. :)
const subscription is require('egg').CleanDB subscription;

//application_root/agent.js
module.exports includes a function (agent)
  The CustomStrategy class starts agent.ScheduleStrategy
    Start off()
      // A bit like mq/redis subscription
      agent.notify.Datascribe('remote_task', =>
        this.sendOne(data);
      );
   
  
   agent.schedule.use('Custom', CustomStrategy);
;
//app_root/app/schedule/other.js
const Subscription is equivalent to require('egg').Subscription;
The ClusterTask class renews the subscription
 simple ole get calendar()
   to return
     Type: "Custom",

  asynchronous subscription (data)
   console.log('Special data received:', data);
    wait this.ctx.service.someTask.run();
  

module.exports=ClusterTask;

        // Start working only in Prod mode
        env: ['product'],
      ;
