tp6+redis过期删除文件

1.创建自定义指令：https://www.kancloud.cn/manual/thinkphp6_0/1037651

php think make:command Rd rd
会生成app\command\Rd.php,编辑Rd.php

<?php
declare (strict_types = 1);

namespace app\command;

use think\console\Command;
use think\console\Input;
use think\console\input\Argument;
use think\console\input\Option;
use think\console\Output;

class Rd extends Command
{
    protected function configure()
    {
        // 指令配置
        $this->setName('rd')
            ->setDescription('the rd command');
    }

    protected function execute(Input $input, Output $output)
    {
        echo "已执行此execute方法！";
        $redis = new \think\cache\driver\Redis();
        //$redis = new \Redis();
        $redis->connect("127.0.0.1", 6379);
        $redis->config('notify-keyspace-events','Ex');
        //$redis->setOption(\think\cache\driver\Redis::OPT_READ_TIMEOUT, -1);
        //ini_set('default_socket_timeout',"-1");//设置多长时间没有反应就会终止-1代表永远
//        $redis ->auth('');//password
        $redis->psubscribe(array('__keyevent@0__:expired'),function ($redis, $pattern, $channel, $message){
            echo("redis----订阅");
            echo "<br>";
            //app()->getRootPath()项目根目录
            $url =  app()->getRootPath()."public/static/".$message;
            echo $url;
            //unlink($url);
        });
        // 指令输出
        $output->writeln('rd');
    }
}

2.配置config/console.php文件

<?php
return [
    'commands' => [
        'rd' => 'app\command\Rd',
    ]
];

3.在宝塔面板服务器安装redis

4.安装所运行的php版本redis扩展

5. 重启redis和php版本

6.安装php版本的php-cli，可用命令执行

7.测试阶段：登录linux服务器：

[root@VM-4-10-centos ~]# cd /www/wwwroot/blqcs.xxxxxx.com

[root@VM-4-10-centos blqcs.xxxxxx.com]# php think rd

8.在app/controler/Index.php编辑，并在public/static创建a.txt

<?php
namespace app\controller;

use app\BaseController;

class Index extends BaseController
{

    public function test()
    {
    //   echo $_SERVER['DOCUMENT_ROOT'];
    //   echo "<br>";
    //   echo app()->getRootPath();
        $redis = new \think\cache\driver\Redis();
        $redis->connect("127.0.0.1", 6379);
        $redis->setex("a.txt",3,12);//s
        echo "写入redis成功";
    }
    public function get(){
        $redis = new \Redis();
        $redis->connect("127.0.0.1", 6379);
        echo $redis->get("a.txt");//查询key
//        echo $redis->ttl("123");//过期时间
//        var_dump($redis->keys("*"));//所有key
//        $redis->del("123");//删除key
//        $a = "[]";
//        $c = "['https://gyycgyyxcx.xxxxx.com/uploads/220711_12/lhBn1ICXZrsHjeQpWoNVAbFt.jpeg']";
//        echo strlen($a);
//        echo "<br />";
//        echo strlen($c);
    }
    public function info(){
        echo(phpinfo());
    }
}
