Guzzle 6 Pool: sink and filename in fulfilled, how to get?

Question

PHP

Please help with guzzle.
There is the following code

$requests = function ($total) use ($client) {
            foreach($this->downloadLinks as $key => $link) {

                preg_match('/([0-9]*)\.mp4/', $link, $matches);
                $resource = getcwd().'/videos/'.$this->downloadPath.'/'.$matches[0];

                yield function () use ($client, $link, $resource) {
                    return $client->getAsync($link, [
                        'sink' => $resource,
                        'proxy' => 'tcp://'.$this->proxies[ mt_rand(0, count($this->proxies)-1)]
                    ]);
                };
            }
        };





        $pool = new Pool($this->browser, $requests(count($requests)), [
            'concurrency' => $concurrency,
            'fulfilled' => function ($response, $index) {
               
               как тут получить имя скачанного фала?

            },
            'rejected' => function ($reason, $index) {
              echo 'rejcted';
            },
        ]);

        $promise = $pool->promise();
        $promise->wait();

Files are downloaded as expected, but how to get the name of the downloaded file in fulfilled?
I can't figure it out.
Thank you!

Answer 1

I did it via middlewears docs.guzzlephp.org/en/latest/handlers-and-middlewa... I
added the necessary data to the Response and already in fulfilled I got them $request->getHeader('custom_header');

Answer 2

Or add an identifier to yield if you need to get something of your own.
Or look repsonse, there should be all the headers and etc.
