Question

我正在尝试使用生产APN服务器向iPad发送MDM推送通知。但是，Push Sharp表示通知失败，因为标识符等于1.来自PushSharp代码库的以下代码说明了它是如何得出结论的......

//We now expect apple to close the connection on us anyway, so let's try and close things
// up here as well to get a head start
//Hopefully this way we have less messages written to the stream that we have to requeue


try { stream.Close(); stream.Dispose(); }
catch { }

//Get the enhanced format response
// byte 0 is always '1', byte 1 is the status, bytes 2,3,4,5 are the identifier of the notification

var identifier = IPAddress.NetworkToHostOrder(BitConverter.ToInt32(readBuffer, 2));

int failedNotificationIndex = -1;
SentNotification failedNotification = null;

//Try and find the failed notification in our sent list
for (int i = 0; i < sentNotifications.Count; i++)
{
    var n = sentNotifications[i];

    if (n.Identifier.Equals(identifier))
    {
        failedNotificationIndex = i;
        failedNotification = n;
        break;
    }
}

基本上，在将有效负载写入流之后，它会尝试关闭连接，在此期间它期望来自APN服务的响应，我认为它称为通知标识符。

我已将设备插入iPhone设备配置实用程序，但控制台中没有任何内容，因此我认为它从未收到此通知。

我的问题是......

它期待的标识符是什么？
我有什么问题吗？

设备正在运行iOS 6.有效负载的结构如下......

{"aps":{},"mdm":"80369651-5802-40A2-A0AE-FCCF02F99589"}

6字节的返回字节[]中的值如下8,8,0,0,0,1

不知道，我从未详细研究过PushSharp如何处理APNS内部细节。
您不应该在通知有效负载中发送＆＃34; aps＆＃34;：{}部分，这可能是APNS未通知的原因。

我已成功使用PushSharp 1.0.17以及以下MDM通知代码，因此它绝对有效。

var pushService = new PushService();
// attach event listeners

// override the production/development auto-detection as it doesn't
// work for MDM certificates
var cert = null; // load your push client certificate
var channel = new ApplePushChannelSettings(true, cert, true);
pushService.StartApplePushService(channel);

// create and send the notification
var notification = NotificationFactory
    .Apple()
    .ForDeviceToken("your-device-token-received-from-checkin")
    .WithExpiry(DateTime.UtcNow.AddDays(1))
    .WithCustomItem("mdm", "your-push-magic-received-in-checkin");
pushService.QueueNotification(notification);

Answer 2

对于PushSharp v3.0 +，您应该能够直接包含在ApnsNotification的Payload中。

public void SendIosMdm(string deviceToken, string pushMagic)
    {
        _apnsBroker.QueueNotification(new ApnsNotification
        {
            DeviceToken = deviceToken,
            Payload = JObject.FromObject(new {
                mdm = pushMagic
            })
        });
    }

无法使用Push Sharp发送iOS MDM推送通知
