php - APNs 消息已发送但未在 iOS 设备上接收

Question

我已经设置了一个转发/调度服务，该服务保持与 APN 的开放连接，如 Apple 所述/推荐的那样，以防止 DoS 检测并且证书正在运行......

我已成功连接并成功发送消息，但 iOS 设备(iPhone)未收到消息...(？!？)发送的字节数等于 fwrite 返回的字节数。

最后，消息可能包含特定国家/地区的字符。 APNs 是如何处理的？以及这些字符应该如何发送到 APNs 服务器？

我尝试过使用和不使用转发服务，但都没有成功。 :-(

代码片段中删除了所有对日志的调用以避免混淆。这意味着粘贴的日志消息不能直接映射到代码片段中，但应该可以“猜测”日志消息的来源。

请帮我解决这些问题。提前致谢

连接是这样建立的:

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', $certPath);
stream_context_set_option($ctx, 'ssl', 'passphrase', $passPhrase);
$this->apn_link = stream_socket_client($url, $err, $errstr, 60,                                       STREAM_CLIENT_CONNECT | STREAM_CLIENT_PERSISTENT, $ctx);
/* ... */

在转发服务上监听套接字的循环中:

foreach ($changed as $changed_socket) {
    while(isset($changed_socket) && socket_recv($changed_socket, $buf, 1024, 0) >= 1)
    {
        $buf = trim($buf);
        if ($buf != '') {
            $this->msg2apn($buf);
        }
    }
}
/* ... */

进一步我以这种方式发送消息:

public function msg2apn($msg) {
if (isset($this->apn_link)) {
    while(!$result = fwrite($this->apn_link, $msg, strlen($msg))) {
        usleep(400000); //400 msec
    }

    if ($result) {
        fflush($this->apn_link);
        return True;
    }
}
}

发送到转发服务的消息:

private function send_pn_iosproxy($msg) {
    $address = IOS_APNPROXY_HOST;
    $port = IOS_APNPROXY_PORT;
    $fp = fsockopen($address,$port);
    if (!$fp) {
        elog("Connection to [".$address.":".$port."] could not be established");
        return False;
    }
    $result = fwrite($fp, $msg, strlen($msg));

    if (isset($fp)) fflush($fp);
    if (isset($fp)) fclose($fp);
    return True;
}

通过以下方式为每个设备 token 生成一条消息:

$payload = '{"aps":{"alert":"'.$message['message'].'","badge" : "1","sound":"default"}}';

foreach($deviceTokens as $deviceToken) {
// Build the binary notification
$msg = chr(0) . pack('n', 32) . base64_decode($deviceToken) . pack('n',    strlen($payload)) . $payload;

// see function above
$result = $this->send_pn_iosproxy($msg);

if ($result) {
    ilog("Message delivered");
    dlog("DeviceToken[$deviceToken], Payload[$payload]");
} else {
    wlog("Message not properly delivered");
    dlog("Msg[$msg]");
    dlog("DeviceToken[$deviceToken], Payload[$payload]");
}
}

logdisp的日志消息来自转发服务，而log的日志消息来自app-/web服务器。 Web 服务器使用 127.0.0.1/localhost 连接到转发服务，因此 Web 服务器和转发服务器托管在同一台物理计算机上。

我尝试发送两种负载:

{"aps" : {"alert" : "message","badge" : "1","sound" : "default"}} 
{"aps" : { "alert" : { "title" : "My Title", "body" : "My Message" }, "badge" : 2, "sound" : "default" } }

重新生成证书后，我现在在连接时收到以下错误:

[vagrant@server backend-src]$ php -f dispatcher.php
Log path: [/srv/backend/log/log.txt], Log level: [0],
Binding info: address[127.0.0.1], port[6060]

我现在可以连接了!这里的原因很简单。证书的路径不正确。但是，具有新证书的设备仍未收到推送通知。

应用程序是否需要使用新证书发布/发布才能运行？？？无论是在开发中还是在生产中，设备上都没有收到消息？？？

最后，它成功接收了沙盒和生产/临时 token 的消息。

// 64 chars token
// Sandbox and productions tokens have the same length and 
// they cannot be distinguished    
$deviceToken='1234567890123456789012345678901234567890123456789012345678901234';

$body['aps'] = array('alert' => 'Sample message', 'sound' => 'default');
$payload = json_encode($body);

$deviceToken = str_replace(' ', '', $deviceToken);
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

fwrite($apn_link, $msg, strlen($msg));
fflush($apn_link);

不要在生产环境中混用沙箱和生产设备 token !

APN 生产环境不允许沙箱 token 并且当已使用沙盒 token 。

不要在生产环境中混用沙箱和生产设备 token !

APN 生产环境不允许使用沙盒 token ，并且在使用沙盒 token 时它会自动停止向生产 token 传送消息。
