Question

我正在尝试向我们应用程序的用户发送FCM推送通知，我需要向每个用户发送13k定制消息，其中每个通知都包含他的姓名和一些数据，因此我需要为每个用户发送FCM请求，我的问题是

如何在不降低性能的情况下发送此数量的请求并增加服务器负载？

因为我尝试了许多答案，并使用“内部服务器错误”使服务器停机，但我也尝试对请求进行循环，并且每个循环使PHP睡眠（1）或更多秒，并且使我超时，所以我尝试了使用set_time_limit和init最大执行时间来增加超时时间，但是一旦我运行PHP文件，它也会给我内部服务器错误。

我正在使用ajax从cPanel调用此PHP文件并且应该做这份工作在PHP脚本中，我每次将用户划分为1000个用户。

$curlResults = array();

$curlRequests = array_chunk($curlRequests, 250);

foreach ($curlRequests as $requests) {

    try {
        $results = $this->executeFCMRequests($requests);
        $curlResults = array_merge($curlResults, $results);
        sleep(2);
    } catch (Exception $e) {
        echo 'Caught exception: ', $e->getMessage(), "\n";

    }
}




function executeFCMRequests($requests)
{

    try {
        $master = curl_multi_init();


        $requests_count = count($requests);

        $curl_arr = array();

        for ($i = 0; $i < $requests_count; $i++) {
            $request = $requests[$i];
            $curl_arr[$i] = $request;
            curl_multi_add_handle($master, $curl_arr[$i]);
        }

        $running = null;
        do {
            curl_multi_exec($master, $running);
        } while ($running > 0);


        for ($i = 0; $i < $requests_count; $i++) {
            $results[] = curl_multi_getcontent($curl_arr[$i]);
            curl_multi_remove_handle($master, $curl_arr[$i]);

        }
        curl_multi_close($master);
    } catch (Exception $e) {
        echo 'Caught exception: ', $e->getMessage(), "\n";

    }

    return $results;
}

如何创建每个请求的请求数组

function createFCMCurlRequest($regIds, $title, $message, $image, $shouldOpen, $shopId, $url, $notificationId)
{

    // API access key from Google API's Console
    define('API_ACCESS_KEY', 'AAAATQ-------------------------------------------');
    $registrationIds = $regIds;

    $msg = array
    (
        'body' => $message,
        'title' => $title,
        // 'Link' => $link
    );



    $data = Array(
        'shouldOpen' => $shouldOpen,
        'notificationId' => $notificationId,
        'shopId' => $shopId,
    );

    if ($url != null) {
        $data['url'] = $url;
    }

    $fields = array
    (
        'registration_ids' => $registrationIds, //$registrationIds,
        'notification' => $msg,
        'data' => $data,
        'content_available' => true,
        'priority' => 'high',
    );

    $headers = array
    (
        'Authorization: key=' . API_ACCESS_KEY,
        'Content-Type: application/json'
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
    curl_setopt($ch, CURLOPT_TIMEOUT, 400);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    return $ch;
}

当我发送请求时，最多2K个请求代码可以正常工作，但超过该服务器的返回值，却出现内部服务器错误或超时甚至ERR空响应。

尝试使用php发送超过10K curl请求时出现问题
