PHP / Swoole Http Server - 如何动态加载ssl？

I need load different ssl certificates on the fly, on process request. I try do it like in code below, but server still loading cert1 certificate on handling request, not cert2 as I trying to do in code.

How can I dynamically reload different certificates on the fly? Is it possible?

Code example:

<?php

require 'vendor/autoload.php';


$server = new swoole_http_server("192.168.10.10", 443, SWOOLE_BASE, SWOOLE_SOCK_TCP | SWOOLE_SSL);

// setup the location of ssl cert files and key files
$ssl_dir = __DIR__.'/ssl_certs';
$server->set([
    'max_conn'           => 500,
    'daemonize'          => false,
    'dispatch_mode'      => 2,
    'buffer_output_size' => 2 * 1024 * 1024,
    'ssl_cert_file' => $ssl_dir . '/cert1.local.crt',
    'ssl_key_file' => $ssl_dir . '/cert1.local.key',
    'open_http2_protocol' => true, // Enable HTTP2 protocol
]);

$server->on('request', function ($request, $response) use ($server) {
    $server->set([
        'ssl_cert_file' => $ssl_dir . '/cert2.local.crt',
        'ssl_key_file' => $ssl_dir . '/cert2.local.key',
    ]);
    $response->end("<h1>Hello World. #".rand(1000, 9999)."</h1>");
});

$server->start();
