APN消息是在iOS设备上传递但未接收到的。

Question

我已经建立了一个转发/调度服务，按照苹果公司的声明/建议，它与an保持一个开放的连接，以防止DoS检测，并且该证书正在工作。

我已成功连接并成功发送消息，但没有在iOS设备(IPhone)上接收消息。(？！)发送的字节数等于fwrite返回的字节数。

最后，消息可能包含特定于国家的字符。APN是怎么处理的？如何将这些字符发送到APN服务器？

我已经尝试过了，无论有没有转发服务，但没有运气。:-(

在代码段中删除对日志的所有调用，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段，但是应该可以“猜测”日志消息的来源。

请在这些问题上帮助我。提前感谢

以这种方式建立连接：

$ctx = stream_context_create();
stream_context_set_option($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);
/* ... */

在侦听转发服务上的套接字的循环中：

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);
        }
    }
}
/* ... */

此外，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;
    }
}
}

发送给转发服务的消息：

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;
}

对于每个设备令牌，以下列方式生成一条消息：

$payload = '{"aps":{"alert":"'.$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]");
}
}

来自logdisp的日志消息来自转发服务，而来自日志的日志消息来自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。

我试图发送两种有效载荷：

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

重新生成证书之后，现在在连接时得到以下错误：

[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！原因很简单。证书的路径不正确。但是，在具有新证书的设备上仍未收到推送通知。

应用程序是否需要发布/发布新的证书才能运行？设备上既没有收到信息，也没有在生产中接收信息？

最后，它成功地接收了沙箱和生产/即席令牌的消息。

// 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);

不要混合沙箱和生产装置令牌的生产！

APN生产环境不允许沙箱令牌，并且在使用沙箱令牌时，它会静默地停止向生产令牌传递消息。

苹果已经改变了很多事情:虽然它仍然允许创建沙箱专用证书，但是生产证书可以在沙箱和生产环境中使用。
