Question

我正在尝试实施APNS（推送通知）。我已经创建了证书等等。一切都是像iv'e做了很多次。但我不能从苹果APNS服务器得到一个错误，似乎一切都好，但我仍然没有得到任何推动设备。这是我用来制作魔法的PHP代码:) 我确保PORTS在托管中开放。

基本上我从数据库中获取用户令牌并使用默认声音发送推送文本。

有人可以看看并告诉我你是否可以在这段代码中看到任何问题，或者让我知道如何从APNS服务器获得过程/响应的真实结果？

    $result = mysql_query($sql);

您无法从Apple获得错误响应，因为您使用的是不会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;

如果您想要一种可以返回错误响应的格式，您可以使用其中一种增强格式。

例如，以1：

开头的格式

msg将以chr(1)开头，后跟4个字节的消息ID，4个字节的到期时间，其余信息将与您现在拥有的pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload

它应该是这样的：

$msg = chr(1) . pack("N", $msg_id) . pack("N", $expiry) . pack('n', 32) . pack('H*', $token) . pack('n', strlen($payload)) . $payload;
