use Hyperf\Utils\Parallel;
use Hyperf\Guzzle\ClientFactory;

/** @var ClientFactory $clientFactory */
$clientFactory = null;

$client = $clientFactory->create([
    'base_uri' => 'https://fcm.googleapis.com/v1/projects/abcedfg/messages:send',
    'timeout' => 5,
    'proxy' => 'tcp://111.222.111.222:1111'
]);

$targets = []; // 数组很大 100000+
$parallel = new Parallel();
foreach($targets as $target) {
    $parallel->add(function () use ($client){
        try {
            $client->post('', [
                'body'    => json_encode(['xxx']),
                'headers' => [
                    'Authorization' => 'Bearer abc...efg',
                    'Content-Type'  => 'application/json',
                ],
            ]);

} catch (\GuzzleHttp\Exception\ClientException $e) {

} catch (\GuzzleHttp\Exception\BadResponseException $e) {

} catch (\GuzzleHttp\Exception\TransferException $e) {
            echo $e->getMessage() . PHP_EOL;
        }
    });
}
$parallel->wait();

```
