未使用 PHP 代码接收/发送推送通知 (iOS)

Question

我正在尝试实现 APNS（推送通知）。 我已经创建了证书，等等。一切都是像我已经完成了很多次一样创建的。 但我无法从苹果 APNS 服务器收到错误，似乎一切正常，但我仍然没有在设备中收到任何推送。 这是我用来制作魔法的 PHP 代码 :) 我确保 PORTS 在主机中打开。

基本上我从数据库中获取用户令牌并发送带有默认声音的推送文本。

有人可以看看并告诉我您是否可以在此代码中看到任何问题，或者让我知道如何从 APNS 服务器获得流程/响应的真实结果？

    $sql = "SELECT * FROM `registration` WHERE `chat_id` ='$opponent_id'";

    $result = mysql_query($sql);

    if (!$result) {
        echo "Could not successfully run query ($sql) from DB: " . mysql_error();

您无法从 Apple 获得错误响应，因为您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：

消息将以chr(1) 开头，然后是 4 个字节的消息 ID，4 个字节的过期时间，其余的消息将与您现在拥有的 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;
