 randomKey

从当前数据库中随机返回一个 key。
實例如：
<?php
use Workerman\Worker;
use Workerman\Redis\Client;
use Workerman\Connection\TcpConnection;
use Workerman\Timer;
require_once __DIR__ . '/vendor/autoload.php';
 
$worker = new Worker('http://0.0.0.0:6161');
 
$worker->onWorkerStart = function() {
 
};
 
$worker->onMessage = function(TcpConnection $connection, $data) {
    $redis = new Client('redis://127.0.0.1:6379');
    $redis->auth("xy220807",function($result){
        var_dump("auth:");
        var_dump($result);
    });
    $redis->randomKey(function($key) use ($redis) {
        var_dump("randomKey_key:".$key);
        $redis->get($key, function ($result) {
            var_dump("randomKey_val:".$result);
        }) ;
    });
 
};
 
Worker::runAll();
實例運行並有http客戶端訪問了兩次后如：
[root@localhost www.fpm.com]# /usr/local/php734/bin/php channelServer.php start
Workerman[channelServer.php] start in DEBUG mode
----------------------------------------- WORKERMAN -----------------------------------------
Workerman version:4.0.22          PHP version:7.3.4
------------------------------------------ WORKERS ------------------------------------------
proto   user            worker          listen                 processes    status
tcp     root            none            http://0.0.0.0:6161    1             [OK]
---------------------------------------------------------------------------------------------
Press Ctrl+C to stop. Start success.
