我想将推送消息广播到多个设备。目前，如果数据库表中只存储了2个（可能是1个或2个）设备令牌，则可以发送消息。对于3个或更多设备令牌，我无法发送推送消息。它甚至不会向先前添加的2个设备发送消息。在服务器端，我可以看到传递的消息，但它们实际上并未传递。
我在开发者资料和分发配置文件上测试了它，但是如果在DB表中只保存了1或2个设备，我只能发送消息。
在这两种情况下，我都使用了一个app id，它被配置用于开发和分发。
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);
/*

}else
{
$token->updateToken($tokenid,$incrementcount);
echo 'Message to the device ' . $arrtokens[$i][0] . ' successfully delivered' . '<br/>';
}
// sleep(10);
}
}
else if($devicetoken != "")
{

答案 0 :(得分：4)
最可能的解释是第3个设备令牌无效。如果您首先发送到此设备令牌，Apple将关闭套接字并忽略其他两个设备的消息，即使它们似乎在服务器端成功传送。 如果您正在混合开发和生产设备令牌，这可以解释为什么其中一些是无效的。如果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）。
