504 Gateway Time-out When sendNotification > 500

[bcat95]

Thanks for this library. I have integrated it into my website and conducted a test submission.

Size subscriptions	Time 1 (s)	Time 2 (s)
100	4	3.7
200	8	7.4
400	14	14.4
800	504 Gateway Time-out	504 Gateway Time-out

It seems that my code was not optimal when sending in bulk! Give me a solution to solve this

Code:

$webPush - > setDefaultOptions([
    'TTL' => 86400, // if undelivered after 1 day, expire the notification
]);

$subscriptions = $this - > getReceiverSubscriptions();

foreach($subscriptions AS $subscription) {
    $authData = json_decode($subscription['data'], true);

    $payload['subscriber_id'] = $subscription['endpoint_id'];

    $array = [
        'endpoint' => $subscription['endpoint'],
        'publicKey' => $authData['key'],
        'authToken' => $authData['token'],
        'contentEncoding' => $authData['encoding']
    ];

    try {
        $webPush - > setAutomaticPadding($this - > getEndpointPadding($subscription['endpoint']));

        $subObj = Subscription::create($array);

        $webPush - > sendNotification(
            $subObj,
            json_encode($payload)
        );
    } catch (\Exception $e) {
        // generally indicates that the payload is too big which at ~3000 bytes shouldn't happen for a typical alert...
        continue;
    }
}

foreach($webPush - > flush() as $report) {
    $results[] = $report - > jsonSerialize();
}
