如何將推送通知發送到多個設備？

Question

這是我第一次在App中使用推送通知。我已經通過示例應用程序以及書籍瞭解瞭如何將推送通知發送到單個設備。但是，我的程序發送推送通知給多個設備。我使用'PushMeBaby'應用程序進行服務器端編碼。 請幫我一把。 在此先感謝。

Answer 1

嘗試此示例代碼並根據您的環境進行修改。

$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); 
    }?>

我發現，你必須創建一個新的stream_context_create每個fwrite都會阻止蘋果關閉壞連接。

這是我做了什麼here

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

      global $obj_basic;   
      // Basic settings 

      $timezone = new DateTimeZone('America/New_York'); 
      $date = new DateTime();
