【问题描述】：

我想将推送消息广播到多个设备。目前，如果数据库表中仅存储 2 个（可能是 1 个或 2 个）设备令牌，我可以发送消息。对于 3 个或更多设备令牌，我无法发送推送消息。它甚至不会向之前添加的 2 个设备发送消息。在服务器端，我可以看到消息已送达，但实际上并未送达。

我在开发人员配置文件和分发配置文件上都对其进行了测试，但是如果数据库表中仅保存 1 或 2 台设备，我只能在两者上发送消息。

在这两种情况下，我都使用了一个为开发和分发而配置的应用 ID。

我的服务器端php代码如下：

<?php
error_reporting(0);
 include 'classfiles/Tokens.php';

if(isset($_POST))


$sender = $_POST['sender'];
$message = $_POST['message'];


$token = new Tokens;
$arrtokens = $token->getTokens();


$devicetoken = $_POST['device_token'];

// Settings
$apnsCert = 'test.pem';//To be changed
$apnsHost = 'gateway.push.apple.com';//To be changed
$apnsPort = 2195;

// Connect to Apple Push Notification server
$streamContext = stream_context_create();
stream_context_set_option($streamContext, 'ssl', 'local_cert', $apnsCert);
stream_context_set_option($streamContext, 'ssl', 'passphrase', 'test123');
//60 -> timeout in seconds
$apns = stream_socket_client('ssl://' . $apnsHost . ':' . $apnsPort, $error, $errorString, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $streamContext);
if (!$apns) 
    die('Error creating ssl socket');


stream_set_blocking ($apns, 0);

echo 'Connected to APNS' . PHP_EOL;

if(is_array($arrtokens))

    //foreach($arrtokens as $key=>$deviceToken)
    for($i=0;$i<count($arrtokens);$i++)
    

        $incrementcount = 0;
        $tokenid = $arrtokens[$i][0];
        $badgecount = $arrtokens[$i][1];
        $incrementcount = $badgecount+1;

        // Prepare payload
        $payload = 
        array(
            'aps' => array(
            'alert' => $message,
            'badge' => $incrementcount,
            'sound' => 'default',
            'sender' => $sender
            )
        );
        $payload = json_encode($payload);

   /*
        // this was also working 

        $apnsMessage =
            chr(1)
            . pack('N', 88)
            . pack('N', time() + 86400)
            . chr(0) . chr(32) 
            . pack('H*', str_replace(' ', '', $tokenid)) 
            . chr(0) . chr(strlen($payload)) 
            . $payload . $payload;
   */

        $apnsMessage = chr(0) .pack('n',32) . pack('H*', str_replace(' ', '', $tokenid)) . chr(0) . chr(strlen($payload)) . $payload;

        // this was also working
        //   $apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $tokenid)) . chr(0) . chr(strlen($payload)) . $payload;

        // this was also working
        //  $apnsMessage = chr(0) . chr(0) . chr(32) . pack('H*', str_replace(' ', '', $device_tokens_array[i])) . chr(0) . chr(strlen($payload)) . $payload;

      //  $result =fwrite($apns, $apnsMessage);



            $result = fwrite($apns, $apnsMessage, strlen($apnsMessage));

        else
        
            $token->updateToken($tokenid,$incrementcount);  
            echo 'Message to the device ' . $arrtokens[$i][0] . ' successfully delivered' . '<br/>';

        


    //  sleep(10);


    

else if($devicetoken != "")

    $apnsMessage = 
            chr(1)
            . pack('N', 88)
            . pack('N', time() + 86400)
            . chr(0) . chr(32) 
            . pack('H*', str_replace(' ', '', $deviceToken))

    if(!$result)
        echo 'Message to the device ' . $token . ' not delivered' . PHP_EOL;
    else
        echo 'Message to the device ' . $token . ' successfully delivered' . PHP_EOL;



usleep(500000);

fclose($apns);



function checkAppleErrorResponse($apns)

$responseBinary = fread($apns, 6);
if ($responseBinary !== false && strlen($responseBinary) == 6)

    print(
        "\n"
        .'Error message recieved from Apple.'."\n"
        .'For the meaning, refer to: "Provider Communication with Apple Push Notification Service"'."\n"
    );

    var_dump($response);

【问题讨论】：

您应该返回并接受您之前提出的问题的答案。关于这个问题，所有注册的设备是否都处于生产模式（他们是否从 App Store 下载了应用程序）？

其中1个处于开发模式，其他4个设备处于生产模式。并且该应用不是从应用商店下载的，我们正在测试该应用。

【参考方案1】：

最可能的解释是第三个设备令牌无效。如果您首先发送到此设备令牌，Apple 会关闭套接字，并且忽略发送到其他两个设备的消息，即使它们似乎在服务器端已成功传递。 如果您正在混合开发和生产设备令牌，那就可以解释为什么其中一些是无效的。如果您使用生产证书打开到 APNS 服务器的套接字，则只有生产设备令牌对该连接有效（反之亦然）。

【讨论】：

现在我已经创建了新证书、新开发者资料、新应用程序 ID，现在我正在 4 台设备上进行测试，它表示已分发到所有设备，但它只发送到第一个设备。跨度>

您使用的是增强格式吗？您是否尝试阅读 Apple 返回的错误响应？您使用的设备令牌之一可能无效。仍然有可能 4 个设备令牌中的一些是开发令牌，而其他是生产令牌，这可以解释问题。也许您应该从数据库中删除设备令牌并从 4 个设备中获取新令牌，以确保它们都是有效的。

我创建了新的应用程序 ID、新的开发人员配置文件和服务器端的一些更改，它现在可以正常工作（我未注释的注释行）。我认为您适合开发人员和分发令牌 ID。我还删除了表中的所有条目。谢谢伊兰。

谢谢！你拯救了我的一天！
