我正在尝试使用生产 APN 服务器将 MDM 推送通知发送到 iPad。但是,Push Sharp 说通知失败是因为标识符等于 1。PushSharp 代码库中的以下代码说明了它是如何得出这个结论的......

//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,但控制台中没有出现任何内容,因此我假设它从未收到此通知。

我的问题是...

  1. 它期望的这个标识符是什么?
  2. 有什么我做错了吗?

设备运行iOS 6。payload的结构如下...

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

返回的6个字节的byte[]中的值如下8,8,0,0,0,1

  1. 不知道,我从来没有研究过 PushSharp 如何处理 APNS 内部的细节。

  2. 您不应该在通知负载中发送 "aps":{} 部分,所以这可能是 APNS 无法通知的原因。

我成功地使用带有以下代码的 PushSharp 1.0.17 进行 MDM 通知,因此它通常可以正常工作。

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);

对于 PushSharp v3.0+,您应该能够直接包含在 ApnsNotification 的有效负载中。

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