thinkphp Queue message queue

Queue Message Queue:

Thinkphp official team developed a dedicated support queue service expansion pack, using the composer management, ease of use

Queue Message Queuing advantages:

1. Queue built Redis, Database, Topthink, Sync these four drivers, as used herein, Redis drive.

2. Queue message queue for large or complicated a little longer and return results require third party interface batch operations, may be used to send text messages, e-mail transmission, push the APP.

3. Message Queue message may be distributed or acquired, execution, deletion, retransmission failure handling, delayed execution, timeout control and other operations.

Queue Message Queue disadvantages:

1. Once the need to process the data added to the task can not be deleted

https://packagist.org/packages/topthink/think-queue

Installation and Configuration:

1. Is installed, command Composer: composer require topthink / think-queue 2.0.x-dev (here, since the version 3.0 supports tp6 used herein, it is mounted tp5.1 Version 2.0.x-dev)

2. Configuration files are located in application / config / queue.php

3. As used herein, the type is Redis, if your current environment is not Redis, then install it yourself

4. Configuration files are as follows:

   <?php
    return [
        'connector'  => 'Redis',               // 可选驱动类型：sync(默认)、Redis、database、topthink等其他自定义类型
        'expire'     => 60,                    // 任务的过期时间，默认为60秒; 若要禁用，则设置为 null
        'default'    => 'default',             // 默认的队列名称
        'host'       => '127.0.0.1',           // redis 主机ip
        'port'       => 6379,                  // redis 端口
        'password'   => '',                    // redis 连接密码
        'select'     => 0,                     // 使用哪一个 db，默认为 db0
        'timeout'    => 0,                     // redis连接的超时时间
        'persistent' => false,                 // 是否是长连接
    ];
   

5. The controller application \ test \ controller \ Index.php

   <?php
   
   namespace app\test\controller;
   
   use think\Controller;
   use think\facade\Cache;
   use think\Queue;
   
   class Index extends Controller
   {
       public function index()
       {
       }
   
       /**
       * 一个使用了队列的 action
       */
       public function actionWithHelloJob()
       {
   
           // 1.当前任务将由哪个类来负责处理。 
           //   当轮到该任务时，系统将生成一个该类的实例，并调用其 fire 方法
           $jobHandlerClassName  = 'app\test\controller\Hello';
   
           // 2.当前任务归属的队列名称，如果为新队列，会自动创建
           $jobQueueName = "helloJobQueue";
   
           // 3.当前任务所需的业务数据 . 不能为 resource 类型，其他类型最终将转化为json形式的字符串
           //   ( jobData 为对象时，存储其public属性的键值对 )
           $jobData = [
               'name' => 'supperl',
               'age' => 22
           ];
   
           // 4.将该任务推送到消息队列，等待对应的消费者去执行
           $isPushed = Queue::push($jobHandlerClassName, $jobData, $jobQueueName);
   
           // database 驱动时，返回值为 1|false  ;   redis 驱动时，返回值为 随机字符串|false
           if ($isPushed !== false) {
               echo date('Y-m-d H:i:s') . " a new Hello Job is Pushed to the MQ" . "<br>";
           } else {
               echo 'Oops, something went wrong.';
           }
       }
   }
   

6. The controller application \ test \ controller \ Hello.php

                   print("<warn>Hello Job has been retried more than 3 times!" . "</warn>\n");
   
                   $job->delete();

                   //$job->release(2); //$delay为延迟时间，表示该任务延迟2秒后再执行
               }

7. Perform create producers pushed to consumers php index.php test/index/actionWithHelloJob

   1. display 2020-03-26 16:13:48 a new Hello Job is Pushed to the MQ<br>

8. Consumer spending php think queue:work --queue helloJobQueue

   1. display

      <info>Hello Job Started. job Data is: array (
      'name' => 'supperl',
      'age' => 22,
      )</info> 
      <info>Hello Job is Fired at 2020-03-26 16:21:34</info> 
      <info>Hello Job is Done!</info> 
      <info>Hello Job has been done and deleted</info>
