Lumen使用笔记十六（封装redis缓存）

1. 封装 App\Cache\BaseCache.php

<?php

namespace App\Cache;

use Illuminate\Support\Facades\Redis;

abstract class BaseCache
{
    /**
     * 1 小时
     */
    public const ONE_HOUR = 60 * 60;

    /**
     * 1 天
     */
    public const ONE_DAY = self::ONE_HOUR * 24;

    /**
     * 7 天
     */
    public const SEVEN_DAY = self::ONE_DAY * 7;

    /**
     * 30 天
     */
    public const ONE_MONTH = self::ONE_DAY * 30;

    /**
     * 365 天
     */
    public const ONE_YEAR = self::ONE_DAY * 365;

    /**
     * @var string
     */
    protected static $connection = 'default';

    /**
     * 缓存默认前缀
     * @var string
     */
    public static $prefix = 'c_wop_';

    /** @var \Illuminate\Redis\Connections\PhpRedisConnection $redis */
    protected $redis;

    /**
     * BaseCache constructor.
     */
    public function __construct()
    {$this->redis = Redis::connection(static::$connection);
    }

    /**
     * @return \Illuminate\Redis\Connections\PhpRedisConnection
     */
    public function getRedis()
    {return $this->redis;}

    /**
     * Notes: 格式换 key
     *
     * @param $format
     * @param mixed ...$key
     * @return string
     */
    public function wrapKey($format, ...$key)
    {return static::$prefix . sprintf($format, ...$key);
    }

    /**
     * Notes: HSET 设置缓存
     *
     * 单个 filed-value (域 - 对) 设置到 hash 表 key 中, 并重置过期时间
     * @param $key
     * @param $field
     * @param $value
     * @param $expire
     * @return bool
     */
    public function hSetExpireReset($key, $field, $value, $expire)
    {$result = $this->redis->hset($key, $field, $value);
        if ($result) {$this->redis->expire($key, $expire);
            return true;
        }
        return false;
    }

    /**
     * Notes: HMSET 设置缓存
     *
     * 多个 filed-value (域 - 对) 设置到 hash 表 key 中, 并重置过期时间
     * @param $key
     * @param array $field
     * @param $expire
     * @return bool
     */
    public function hMsetExpireReset($key, array $field, $expire)
    {$result = $this->redis->hmset($key, $field);
        if ($result) {$setExipre = $this->redis->expire($key, $expire);
            if ($setExipre) {return true;}
            return false;
        }
        return false;
    }
}

2. 封装 App\Cache\AppCache.php

<?php

namespace App\Cache;

use WptCommon\Library\Facades\MLogger;

class AppCache extends BaseCache
{
    /**
     * @var string
     */
    public static $prefix = 'c_app_';

    /**
     * Notes: 设置账号状态 && 应用状态缓存, 重置过期时间
     *
     * @param $key
     * @param array $field
     * @param $expire
     * @return bool
     */
    public function setAppCacheReset($key, array $field, $expire = self::ONE_DAY)
    {
        $content = [
            'key' => $key,
            'filed' => $field,
            'expire' => $expire
        ];
        $key = $this->wrapKey($key);
        $result = $this->hMsetExpireReset($key, $field, $expire);
        if ($result) {return true;}
        MLogger::info('setAppCacheReset', ' 设置账号状态和应用状态缓存失败 ', $content);
        return false;
    }

    /**
     * Notes: 删除应用 key 缓存
     *
     * @param $key
     * @return bool
     */
    public function delAppCache($key)
    {$key = $this->wrapKey($key);
        $result = $this->getRedis()->del($key);
        if ($result) {return true;}
        MLogger::info('setAppCacheReset', ' 删除应用 key 缓存失败 ', ['key' => $key]);
        return false;
    }
}
