我正在尝试实现APNS(推送通知)。我已经创建了证书等等。一切都像我做过很多次的那样。但是我不能从苹果APNS服务器得到一个错误，似乎一切都很好，但我仍然没有在设备上得到任何推送。这是我使用的PHP代码，使魔术:)我确保主机上的端口是打开的。
基本上我从DB获取用户令牌并发送带有默认声音的推送文本。
有人可以看看，告诉我，如果你能在这个代码中看到任何问题，或者让我知道我怎么能从APNS服务器得到过程/响应的真实结果?

你无法从Apple获得错误响应，因为你使用的是不返回错误响应的简单二进制格式:
$msg = chr(0) . pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload;
如果你想要一种可以返回错误响应的格式，你可以使用一种增强格式。
例如，以1开头的格式:
消息将以chr(1)开头，后面是4字节的消息ID, 4字节的过期时间消息的其余部分将与您现在拥有的pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload相同
应该是这样的:
$msg = chr(1) . pack("N", $msg_id) . pack("N", $expiry) . pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload;
