简单demo 演示swoole_timer_tick 消费redis 的队列-优快云博客

本文介绍如何使用PHP和Redis构建一个简单的消息队列系统。通过实例演示了消息的生产和消费过程，包括PHP脚本如何连接到Redis服务器、设置认证、推送消息到列表以及定时消费这些消息。

先上生产对象

<?php

$redis=new Redis();

$redis->connect('127.0.0.1',6379);

$redis->auth('tb');

for($i=0;$i<10;$i++){
  $res[]=$redis->lpush('lists',$i);
}

var_dump($res);

生产

root@tb:/usr/share/nginx/swoole_redis# php producter.class.php 
array(10) {
  [0]=>
  int(71)
  [1]=>
  int(72)
  [2]=>
  int(73)
  [3]=>
  int(74)
  [4]=>
  int(75)
  [5]=>
  int(76)
  [6]=>
  int(77)
  [7]=>
  int(78)
  [8]=>
  int(79)
  [9]=>
  int(80)
}

通过cli看看list长度

127.0.0.1:6379> llen lists
(integer) 80
127.0.0.1:6379>

上消费对象

<?php
  class Customer{
  private static $_instance;
  private static $host;
  private static $port;
  private static $password;
  private static $list;
  private static $redisObj;


  private function __construct(){

        $redis=new Redis();
        $redis->connect(self::$host,self::$port);
        $redis->auth=self::$password;
        self::$_instance=$this;
        self::$redisObj=$redis;
        return self::$_instance;
  }

  public static function instance(array $param){
    self::$host=$param['host'];
    self::$port=$param['port'];
    self::$password=$param['password'];
    self::$list=$param['list'];
    if(!empty(self::$_instance)){
      return self::$_instance;
    }else{
      return new self();
    }
  }

  public function getMsg(){
    return self::$redisObj->rPop(self::$list);
  }
｝

swoole_timer_tick('1000',function(){
  $params['host']='127.0.0.1';
  $params['port']=6379;
  $params['password']='tb';
  $params['list']='lists';//KEY 为lists
  $s=Customer::instance($params);
  var_dump( $s->getMsg());
});

消费，

root@tb:/usr/share/nginx/swoole_redis# php  customer.php 
string(1) "0"
string(1) "1"
string(1) "2"
string(1) "3"
string(1) "4"
string(1) "5"
string(1) "6"
string(1) "7"
string(1) "8"
string(1) "9"
string(1) "0"
string(1) "1"
string(1) "2"
string(1) "3"
string(1) "4"
^C
root@tb:/usr/share/nginx/swoole_redis#

消费了15个，还剩下65个

127.0.0.1:6379> llen lists
(integer) 80
127.0.0.1:6379> llen lists
(integer) 65
127.0.0.1:6379>
