簡單 Redis 連接池示例

安裝 easyswoole/redis 組件：

composer require easyswoole/redis

定義 RedisPool 管理器：

基于 AbstractPool 實現：

新增文件 \App\Pool\RedisPool.php，內容如下：

<?php
/**
 * This file is part of EasySwoole.
 *
 * @link http://www.b3f21.cn
 * @document http://www.b3f21.cn
 * @contact http://www.b3f21.cn/Preface/contact.html
 * @license https://github.com/easy-swoole/easyswoole/blob/3.x/LICENSE
 */

namespace App\Pool;

use EasySwoole\Pool\AbstractPool;
use EasySwoole\Pool\Config;
use EasySwoole\Redis\Config\RedisConfig;
use EasySwoole\Redis\Redis;

class RedisPool extends AbstractPool
{
    protected $redisConfig;

    /**
     * 重寫構造函數，為了傳入 redis 配置
     * RedisPool constructor.
     * @param Config      $conf
     * @param RedisConfig $redisConfig
     * @throws \EasySwoole\Pool\Exception\Exception
     */
    public function __construct(Config $conf, RedisConfig $redisConfig)
    {
        parent::__construct($conf);
        $this->redisConfig = $redisConfig;
    }

    protected function createObject()
    {
        // 根據傳入的 redis 配置進行 new 一個 redis 連接
        $redis = new Redis($this->redisConfig);
        return $redis;
    }
}

或者基于 MagicPool 實現：

<?php
/**
 * This file is part of EasySwoole.
 *
 * @link http://www.b3f21.cn
 * @document http://www.b3f21.cn
 * @contact http://www.b3f21.cn/Preface/contact.html
 * @license https://github.com/easy-swoole/easyswoole/blob/3.x/LICENSE
 */

namespace App\Pool;

use EasySwoole\Pool\Config;
use EasySwoole\Pool\MagicPool;
use EasySwoole\Redis\Config\RedisConfig;
use EasySwoole\Redis\Redis;

class RedisPool1 extends MagicPool
{
    /**
     * 重寫構造函數，為了傳入 redis 配置
     * RedisPool constructor.
     * @param Config $config 連接池配置
     * @param RedisConfig $redisConfig
     * @throws \EasySwoole\Pool\Exception\Exception
     */
    public function __construct(Config $config, RedisConfig $redisConfig)
    {
        parent::__construct(function () use ($redisConfig) {
            $redis = new Redis($redisConfig);
            return $redis;
        }, $config);
    }
}

注冊連接池管理對象

在 EasySwooleEvent.php 中的 initialize/mainServerCreate 事件中注冊，然后可以在控制器中獲取連接池然后進行獲取連接：

<?php
/**
 * This file is part of EasySwoole.
 *
 * @link http://www.b3f21.cn
 * @document http://www.b3f21.cn
 * @contact http://www.b3f21.cn/Preface/contact.html
 * @license https://github.com/easy-swoole/easyswoole/blob/3.x/LICENSE
 */

namespace EasySwoole\EasySwoole;

use EasySwoole\EasySwoole\AbstractInterface\Event;
use EasySwoole\EasySwoole\Swoole\EventRegister;

class EasySwooleEvent implements Event
{
    public static function initialize()
    {
        date_default_timezone_set('Asia/Shanghai');

        $config = new \EasySwoole\Pool\Config();

        $redisConfig1 = new \EasySwoole\Redis\Config\RedisConfig(Config::getInstance()->getConf('REDIS1'));
        $redisConfig2 = new \EasySwoole\Redis\Config\RedisConfig(Config::getInstance()->getConf('REDIS2'));

        // 注冊連接池管理對象
        \EasySwoole\Pool\Manager::getInstance()->register(new \App\Pool\RedisPool($config, $redisConfig1), 'redis1');
        \EasySwoole\Pool\Manager::getInstance()->register(new \App\Pool\RedisPool($config, $redisConfig2), 'redis2');
    }

    public static function mainServerCreate(EventRegister $register)
    {

    }
}

調用

在控制器中獲取連接池中連接對象，進行調用：

<?php
/**
 * This file is part of EasySwoole.
 *
 * @link http://www.b3f21.cn
 * @document http://www.b3f21.cn
 * @contact http://www.b3f21.cn/Preface/contact.html
 * @license https://github.com/easy-swoole/easyswoole/blob/3.x/LICENSE
 */

namespace App\HttpController;

use EasySwoole\Http\AbstractInterface\Controller;

class Index extends Controller
{
    public function index()
    {
        // 取出連接池管理對象，然后獲取連接對象（getObject）
        $redis1 = \EasySwoole\Pool\Manager::getInstance()->get('redis1')->getObj();
        $redis2 = \EasySwoole\Pool\Manager::getInstance()->get('redis2')->getObj();

        $redis1->set('name', '仙士可');
        var_dump($redis1->get('name'));

        $redis2->set('name', '仙士可2號');
        var_dump($redis2->get('name'));

        // 回收連接對象（將連接對象重新歸還到連接池，方便后續使用）
        \EasySwoole\Pool\Manager::getInstance()->get('redis1')->recycleObj($redis1);
        \EasySwoole\Pool\Manager::getInstance()->get('redis2')->recycleObj($redis2);

        // 釋放連接對象（將連接對象直接徹底釋放，后續不再使用）
        // \EasySwoole\Pool\Manager::getInstance()->get('redis1')->unsetObj($redis1);
        // \EasySwoole\Pool\Manager::getInstance()->get('redis2')->unsetObj($redis2);
    }
}
