Question

这是我第一次在我的App中使用推送通知。我已经通过示例应用程序和书籍，我得到了如何将推送通知发送到单个设备。但我没有得到我应该做什么更改在我的程序中向多个设备发送推送通知。我正在使用'PushMeBaby'应用程序进行服务器端编码。拜托，帮帮我吧。在此先感谢。

Answer 1

尝试此示例代码并根据您的环境进行修改。

    $apnsHost = '<APNS host>';
    $apnsPort = <port num>;
    $apnsCert = '<cert>';

    $streamContext = stream_context_create();
    stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);

    $apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 60, STREAM_CLIENT_CONNECT, $streamContext);

    $payload['aps'] = array('alert' => 'some notification', 'badge' => 0, 'sound' => 'none');
    $payload = json_encode($payload);

// Note: $device_tokens_array has list of 5 devices' tokens

    for($i=0; $i<5; $i++)
    {
            $apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $device_tokens_array[i])) . chr(0) . chr(strlen($payload)) . $payload;

            fwrite($apns, $apnsMessage);
    }?>

我发现你必须为每个fwrite创建一个新的stream_context_create，以防止苹果关闭一个坏令牌的连接。

这就是我所做的here

<?php 
        set_time_limit(0);
        $root_path = "add your root path here"; 
        require_once($root_path."webroot\cron\library\config.php");
        require_once($root_path."Vendor\ApnsPHP\Autoload.php");

            global $obj_basic;           
            // Basic settings

            $timezone = new DateTimeZone('America/New_York');
            $date = new DateTime();
            $date->setTimezone($timezone);
            $time =  $date->format('H:i:s');


            //Get notifications data to send push notifications
            $queueQuery = " SELECT `notifications`.*, `messages`.`mes_message`, `messages`.`user_id`, `messages`.`mes_originated_from`  FROM `notifications`
                                            INNER JOIN `messages`
                                            ON `notifications`.`message_id` = `messages`.`mes_id`

                                            WHERE `notifications`.`created` <= NOW()";

            $queueData = $obj_basic->get_query_data($queueQuery);

            if(!empty($queueData)) {

            // Put your private key's passphrase here:
            $passphrase = 'Push';

            $ctx = stream_context_create();

            exit("Failed to connect: $err $errstr" . PHP_EOL);

                foreach($queueData as $val) {

                        // Create message

                            // Get total unread messaged for receiver

                            $message .= " This is a test message.";


                        // Create the payload body
                        $body['aps'] = array(
