我正在尝试实现 APNS(推送通知)。我已经创建了证书等。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 在主机中是打开的。

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?

<?php
    error_reporting(0);
    header("Content-type: application/json; charset=utf-8");

    $users = array();

    $opponent_id = $_REQUEST['opponent_id'];
    $sender_id = $_REQUEST['sender_id'];
    $message = $_REQUEST['message'];

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

    $result = mysql_query($sql);

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

    if (mysql_num_rows($result) == 0) {
        echo "No rows found, nothing to print so am exiting";
        exit;
    }

    while ($row = mysql_fetch_assoc($result)) {
            $token = $row['token'];

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:

msg 以 开头chr(1),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相同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;
