场景:项目中到处可见的key，没有统一管理，极其难维护。大佬同事实现了一个。

代码

如图,Redis.php 是对redis的二次封装，对redis key模块的强制校验，FillerKeyTrait.php 是对filler模块的key获取。主要原理是:对redis二次封装，统一调用入口，对key的获取通过 方法获取，对key根据配置的MODULES进行校验。
一.对redis二次封装
Redis.php代码

<?php

namespace common\cache;

use common\cache\keys\FillerKeyTrait;
use common\tools\Dingtalk;
use yii\helpers\Inflector;
use yii\redis\Connection;

class Redis extends Connection
{
    const YEAR = 60*60*24*365;
    const DAY = 60*60*24;
    const MONTH = 60*60*24*31;
    use FillerKeyTrait;
    const checkCommands = [
        'set',
        'setex',
        'setnx',
        'getset',
        'hmset',
        'hset',
        'hsetnx',
        'lset',
        'psetex',
        'setbit',
        'incr',
        'incrby',
        'zincrby',
        'incrbyfloat',
        'hincrby',
        'hincrbyfloat',
        'decr',
        'decrby',
        'lpush',
        'lpushx',
        'rpush',
        'rpushx',
        'lset',
        'linsert',
        'sadd',
        'zadd',
    ];

    //均已空数组结尾
    const MODULES = [
        'filler' => [

        ],
    ];
    public function __call($name, $params)
    {
        $redisCommand = strtoupper(Inflector::camel2words($name, false));
        if (in_array($redisCommand, self::checkCommands)) {
            if (!$this->checkKey($params[0])) {
                return;
            }
        }

        return parent::__call($name, $params);
    }

    public function get($key)
    {
        $value = parent::get($key);
        $result = unserialize($value);
//        if (!empty($value) && empty($result)) {
//            $result = $value;
//        }

        return $result;
    }

    public function set($key, $value, ...$options)
    {
        if (!$this->checkKey($key)) {
            return;
        }
        $value = serialize($value);
        return parent::set($key, $value, $options);
    }

    public function setex($key, $seconds, $value)
    {
        $value = serialize($value);
        return parent::setex($key, $seconds, $value);
    }

    public function setnx($key, $value)
    {
        $value = serialize($value);
        return parent::setnx($key, $value);
    }

    public function hset($key, $field, $value)
    {
        $value = serialize($value);
        return parent::hset($key, $field, $value);
    }

    public function hget($key, $field)
    {
        $value = parent::hget($key, $field);
        $result = unserialize($value);

        return $result;
    }

    private function checkKey($key)
    {
        try {
            //格式校验, 字母
            $arr = explode(':', $key);
            $count = count($arr);
            if ($count <= 2) {
                throw_info('缓存键名不合法');
            }
            if (strlen($key) > 64) {
                throw_info('缓存键名长度不能大于64位');
            }
            $modules = self::MODULES;
            foreach ($arr as $k => $v) {
                if (($k+1) == $count) {
                    continue;
                }
                if (!isset($modules[$v])) {
                    throw_info('缓存键名未配置');
                }
                $modules = $modules[$v];
            }
            return true;
        } catch (\Throwable $e) {
            if (YII_ENV != 'prod') {
                Dingtalk::sendMessageToRobot(SYSTEM_EXCEPTIONS, "{$key}缓存键名异常".$e->getMessage(), [GUOJUENENG_MOBILE]);
            }
//            throw_info('系统繁忙,缓存异常');
            return false;
        }
    }
}
二、通过train 解耦和通过方法动态组建key

FillerKey.php

<?php

namespace common\cache\keys;

trait FillerKeyTrait
{
    public static function getFiller($platformType, $platformId, $day = '')
    {
        if (empty($day)) {
            $day = date('ymd');
        }
        return 'filler:' . $day . $platformId . ':' . $platformType;
    }
}

$key = Redis::getFiller(19,20,‘2023-12-12 09:12:23’);
三、yii2 redis初始化类直接调用 common\framework\Redis 或者读取后重启一个redis引用

return [
    //common\framework\Redis 
    'class' => 'yii\redis\Connection',
    'hostname'=>'xxxxxxxx',
    'port' => 6379,
    'database' => 1,
    'password' => 'xxxxxx',
//    'password' => '',
];

$goodsRedis = $redis;
$goodsRedis['database'] = 4;
$goodsRedis['class'] = 'common\framework\Redis';

四、全局入口

if (!function_exists('get_cache')) {

    /**
     * 获取商品专用redis对象
     * @return \common\framework\Redis
     */
    function get_cache()
    {
        return \Yii::$app->goodsRedis;
    }
}
