简单demo 演示swoole_timer_tick 消费redis 的队列

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>
