laravel 監聽redis key過時的進行回調

1.修改redis 配置

開啓redis.conf 文件中 notify-keyspace-events Ex

或者 在redis-cli 客戶端輸入以下命令:
config set notify-keyspace-events Ex

2.修改laravel database.php

//datebase.php配置頁面
'redis' => [
        'client' => 'predis',
        'default' => [
            'host' => env('REDIS_HOST', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_PORT', 6379),
            'database' => 0,
            "queue" => '{default}',//queue站點默認走的redis
        ],
        'publisher' => [ //redis 訂閱監聽
                    'host' => env('REDIS_HOST', '127.0.0.1'),
                    'password' => env('REDIS_PASSWORD', null),
                    'port' => env('REDIS_PORT', 6379),
                    'database' => 0,
                    "read_write_timeout"=>0,//長鏈接不要斷
                ],
           ]

3.在腳本的地方實現監聽方法

$redis=Redis::connection('publisher');//建立新的實例
        $redis->psubscribe(['__keyevent@*__:expired'], function ($message, $channel) {
            echo $channel.PHP_EOL;//訂閱的頻道
            echo $message.PHP_EOL;//過時的key
            echo '---'.PHP_EOL;
        });
