Guzzle Pool: ba da proxy na kowane aiki ga requestAsync

Saka proxy na kowane aikin Guzzle a kan aikin async da pool ke farawa. A cikin saitin abokin ciniki da ke akwai, yi amfani da masana'antun alkawari:

$operations = function () use ($client, $jobs) {
    foreach ($jobs as $id => $job) {
        yield $id => function () use ($client, $job) {
            return $client->requestAsync('GET', $job['url'], [
                'proxy' => $job['proxy'],
                'timeout' => 20,
            ]);
        };
    }
};

$pool = new GuzzleHttp\Pool($client, $operations(), [
    'concurrency' => 4,
]);
$pool->promise()->wait();

Kowane ingantaccen aiki yana ba da manufa da proxy.
