我们正在为 iOS 设备开发 MDM 解决方案。

我们已经能够通过网站安装带有 MDM-Payload 的配置文件，并且我们已经收到 iOS 设备发送的包含 PushMagic、deviceToken 和其他值的 PUT 请求。

我们使用以下描述创建了一个 COMPANY.pem SSL 证书: http://www.softhinker.com/in-the-news/iosmdmvendorcsrsigning

我们尝试使用库 push-sharp 发送推送通知: https://github.com/Redth/PushSharp

我们使用这些命令构建 MDM.p12 文件

openssl pkcs12 -export -in ./COMPANY.pem -inkey ./customerPrivateKey.pem -certfile ./CertificateSigningRequest.certSigningRequest -out MDM.p12

发送此通知的程序没有抛出任何错误并正常退出。 但是我们在我们的设备上没有收到任何推送通知，也没有通过反馈服务收到任何东西。

另外值得一提的是，我们也尝试使用沙箱服务器和生产服务器。

这是我们使用 push-sharp 库的代码:

    using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.IO;
using System.Linq;
using System.Text;
using PushSharp;
using PushSharp.Apple;


namespace PushSharp.Sample
{
    class Program
    {
        static void Main(string[] args)
        {

            //Create our service    
            PushService push = new PushService();

            //Wire up the events
            push.Events.OnDeviceSubscriptionExpired += new Common.ChannelEvents.DeviceSubscriptionExpired(Events_OnDeviceSubscriptionExpired);
            push.Events.OnDeviceSubscriptionIdChanged += new Common.ChannelEvents.DeviceSubscriptionIdChanged(Events_OnDeviceSubscriptionIdChanged);
            push.Events.OnChannelException += new Common.ChannelEvents.ChannelExceptionDelegate(Events_OnChannelException);
            push.Events.OnNotificationSendFailure += new Common.ChannelEvents.NotificationSendFailureDelegate(Events_OnNotificationSendFailure);
            push.Events.OnNotificationSent += new Common.ChannelEvents.NotificationSentDelegate(Events_OnNotificationSent);

            //Configure and start Apple APNS
            // IMPORTANT: Make sure you use the right Push certificate.  Apple allows you to generate one for connecting to Sandbox,
            //   and one for connecting to Production.  You must use the right one, to match the provisioning profile you build your
            //   app with!
            //var appleCert = File.ReadAllBytes("C:\\TEMP\\apns-mdm.p12");
            var appleCert = File.ReadAllBytes(@".\MDM.p12");

            //IMPORTANT: If you are using a Development provisioning Profile, you must use the Sandbox push notification server 
            //  (so you would leave the first arg in the ctor of ApplePushChannelSettings as 'false')
            //  If you are using an AdHoc or AppStore provisioning profile, you must use the Production push notification server
            //  (so you would change the first arg in the ctor of ApplePushChannelSettings to 'true')
            push.StartApplePushService(new ApplePushChannelSettings(true, appleCert, "PWD"));


            //String p12File = @".\apns-mdm.p12";
            //String p12Password = "PWD";
            String pushMagicString = "00454668-00B2-4122-A1DC-72ACD64E6AFB";

            String test = "3d 58 64 4d 90 d3 18 09 22 5c 50 d2 12 16 b5 67 71 1e be 5c 13 6e 41 3c 3e 81 b5 52 30 68 09 a5";

            Console.WriteLine("PushMagic is: " + pushMagicString);

            DateTime dayAfterTomorrow = DateTime.Now.AddDays(2);
            Console.WriteLine("Expiry date is: " + dayAfterTomorrow.ToString());

            push.QueueNotification(NotificationFactory.Apple()
                .ForDeviceToken(test).WithExpiry(dayAfterTomorrow).WithCustomItem("mdm", pushMagicString));


            //push.Events.RaiseNotificationSent(NotificationFactory.Apple()
            //    .ForDeviceToken(hex).WithCustomItem("mdm", pushMagicString));

            //Stop and wait for the queues to drains
            push.StopAllServices(true);

            Console.WriteLine("Queue Finished, press return to exit...");
            Console.ReadLine();
        }

        static void Events_OnDeviceSubscriptionIdChanged(Common.PlatformType platform, string oldDeviceInfo, string newDeviceInfo)
        {
            //Currently this event will only ever happen for Android GCM
            Console.WriteLine("Device Registration Changed:  Old-> " + oldDeviceInfo + "  New-> " + newDeviceInfo);
        }

        static void Events_OnNotificationSent(Common.Notification notification)
        {
            Console.WriteLine("Sent: " + notification.Platform.ToString() + " -> " + notification.ToString());
        }

        static void Events_OnNotificationSendFailure(Common.Notification notification, Exception notificationFailureException)
        {
            Console.WriteLine("Failure: " + notification.Platform.ToString() + " -> " + notificationFailureException.Message + " -> " + notification.ToString());
        }

        static void Events_OnChannelException(Exception exception)
        {
            Console.WriteLine("Channel Exception: " + exception.ToString());
        }

        static void Events_OnDeviceSubscriptionExpired(Common.PlatformType platform, string deviceInfo)
        {
            Console.WriteLine("Device Subscription Expired: " + platform.ToString() + " -> " + deviceInfo);
        }
    }
}

我们使用这个网站对接收到的 deviceToken 进行了编码: http://home.paulschou.net/tools/xlate/ 从 base64 到 HEX。

我们还在 iOS 设备上使用 APS/PC 日志记录配置文件，以通过 IPCU 提供的调试控制台获得更多输出。

最佳答案

发送到推送通知服务的消息不得包含 aps 键。该消息应仅包含 PushMagic 字符串作为 mdm 键的值。例如，使用您定义为 pushMagicString 的值，推送通知服务的消息应如下所示:

{"mdm":"00454668-00B2-4122-A1DC-72ACD64E6AFB"}

我没有使用过你正在使用的 push-sharp 库。但是，我简要浏览了代码，似乎 AppleNotificationPayload.ToJson 方法总是向消息添加 aps 键。我建议注释掉第 114 行然后尝试。这是注释掉该行的 ToJson 方法:

    public string ToJson()
    {
        JObject json = new JObject();

        JObject aps = new JObject();

        if (!this.Alert.IsEmpty)
        {
            if (!string.IsNullOrEmpty(this.Alert.Body)
                && string.IsNullOrEmpty(this.Alert.LocalizedKey)
                && string.IsNullOrEmpty(this.Alert.ActionLocalizedKey)
                && (this.Alert.LocalizedArgs == null || this.Alert.LocalizedArgs.Count <= 0)
                && !this.HideActionButton)
            {
                aps["alert"] = new JValue(this.Alert.Body);
            }
            else
            {
                JObject jsonAlert = new JObject();

                if (!string.IsNullOrEmpty(this.Alert.LocalizedKey))
                    jsonAlert["loc-key"] = new JValue(this.Alert.LocalizedKey);

                if (this.Alert.LocalizedArgs != null && this.Alert.LocalizedArgs.Count > 0)
                    jsonAlert["loc-args"] = new JArray(this.Alert.LocalizedArgs.ToArray());

                if (!string.IsNullOrEmpty(this.Alert.Body))
                    jsonAlert["body"] = new JValue(this.Alert.Body);

                if (this.HideActionButton)
                    jsonAlert["action-loc-key"] = new JValue((string)null);
                else if (!string.IsNullOrEmpty(this.Alert.ActionLocalizedKey))
                    jsonAlert["action-loc-key"] = new JValue(this.Alert.ActionLocalizedKey);

                aps["alert"] = jsonAlert;
            }
        }

        if (this.Badge.HasValue)
            aps["badge"] = new JValue(this.Badge.Value);

        if (!string.IsNullOrEmpty(this.Sound))
            aps["sound"] = new JValue(this.Sound);

        if (this.ContentAvailable.HasValue)
            aps["content-available"] = new JValue(this.ContentAvailable.Value);

        //json["aps"] = aps;

        foreach (string key in this.CustomItems.Keys)
        {
            if (this.CustomItems[key].Length == 1)
                json[key] = new JValue(this.CustomItems[key][0]);
            else if (this.CustomItems[key].Length > 1)
                json[key] = new JArray(this.CustomItems[key]);
        }

        string rawString = json.ToString(Newtonsoft.Json.Formatting.None, null);

        StringBuilder encodedString = new StringBuilder();
        foreach (char c in rawString)
        {
            if ((int)c < 32 || (int)c > 127)
                encodedString.Append("\\u" + String.Format("{0:x4}", Convert.ToUInt32(c)));
            else
                encodedString.Append(c);
        }
        return rawString;// encodedString.ToString();
    }
