【问题描述】：

我已经在 c# 中为 ios 中的推送通知开发了代码，但它没有在移动设备中发送通知。 我用过 pushsharp 库。

我的代码如下：

PushNotificationApple pushNotification = new PushNotificationApple();
pushNotification.SendNotification(postData);

我的 PushNotificationApple 构造函数代码如下：-

public PushNotificationApple()
        
            if (_pushBroker == null)
            
                //Create our push services broker
                _pushBroker = new PushBroker();

                //Wire up the events for all the services that the broker registers
                _pushBroker.OnNotificationSent += NotificationSent;
                _pushBroker.OnChannelException += ChannelException;
                _pushBroker.OnServiceException += ServiceException;
                _pushBroker.OnNotificationFailed += NotificationFailed;
                _pushBroker.OnDeviceSubscriptionExpired += DeviceSubscriptionExpired;
                _pushBroker.OnDeviceSubscriptionChanged += DeviceSubscriptionChanged;
                _pushBroker.OnChannelCreated += ChannelCreated;
                _pushBroker.OnChannelDestroyed += ChannelDestroyed;


                var appleCert = File.ReadAllBytes(System.Web.Hosting.HostingEnvironment.MapPath("~/Certificates" + ConfigSettings.SnaptymAPNSCertificate));


                _pushBroker.RegisterAppleService(new ApplePushChannelSettings(false, appleCert,ConfigSettings.SnaptymAPNSPassword)); //Extension method                
            
        

我的 SendNotification 功能如下：-

public bool SendNotification(GcmNotificationPostDataModel postData)
        

            if (_pushBroker != null)
            
                foreach (var registrationId in postData.RegistrationIds)
                

                    _pushBroker.QueueNotification(new AppleNotification()
                                                .ForDeviceToken(registrationId) //the recipient device id
                                                .WithAlert(postData.Data.Message) //the message
                                                .WithBadge(1)
                                                .WithSound("sound.caf"));

                
            

            return true;
        

【问题讨论】：

您收到什么错误？您可以在推送代理的不同事件中跟踪该过程。检查是否有异常

确保你不是这种情况***.com/questions/28499395/…

@patel 很好地呼吁生产环境，但目前 OP 正在发送到沙箱。可以在new ApplePushChannelSettings(false, ....)的第一个参数中看到，而且，这会引发异常。

您的代码正在向苹果的沙箱服务器发送消息。确保您的 ios 应用程序也配置为在沙盒服务器上注册（即使用开发配置文件构建！），就像@patel 所说：为所有推送代理的事件添加处理程序，并查看是否引发任何错误事件。

【参考方案1】：

我正在使用 PushSharp 4.0.10，以下代码适用于我。

     private void SendMessage()
        
            //IOS
            var MainApnsData = new JObject();
            var ApnsData = new JObject();
            var data = new JObject();

            MainApnsData.Add("alert", Message.Text.Trim());
            MainApnsData.Add("badge", 1);
            MainApnsData.Add("Sound", "default");

            data.Add("aps", MainApnsData);

            ApnsData.Add("CalledFromNotify", txtboxID.Text.Trim());
            data.Add("CustomNotify", ApnsData);

            //read the .p12 certificate file
            byte[] bdata = System.IO.File.ReadAllBytes(Server.MapPath("~/App_Data/CertificatesPushNew.p12"));

 //create push sharp APNS configuration
            var config = new ApnsConfiguration(ApnsConfiguration.ApnsServerEnvironment.Sandbox,bdata,"YourPassword");


            //create a apnService broker
            var apnsBroker = new ApnsServiceBroker(config);

            // Wire up events
            apnsBroker.OnNotificationFailed += (notification, aggregateEx) => 

                aggregateEx.Handle(ex => 

                    // See what kind of exception it was to further diagnose
                    if (ex is ApnsNotificationException)
                    
                        var notificationException = (ApnsNotificationException)ex;

                        // Deal with the failed notification
                        var apnsNotification = notificationException.Notification;
                        var statusCode = notificationException.ErrorStatusCode;

                        Console.WriteLine($"Apple Notification Failed: ID=apnsNotification.Identifier, Code=statusCode");

                    
                    else
                    
                        // Inner exception might hold more useful information like an ApnsConnectionException           
                        Console.WriteLine($"Apple Notification Failed for some unknown reason : ex.InnerException");
                    

                    // Mark it as handled
                    return true;
                );
            ;

            apnsBroker.OnNotificationSucceeded += (notification) => 
                Console.WriteLine("Apple Notification Sent!");
            ;

            var fbs = new FeedbackService(config);
            fbs.FeedbackReceived += (string deviceToken1, DateTime timestamp) =>
            
                //Remove the deviceToken from your database
                // timestamp is the time the token was reported as expired
                Console.WriteLine("Feedback received!");
            ;
            fbs.Check();

            // Start the broker
            apnsBroker.Start();

            var deviceToken = "Your device token";
            // Queue a notification to send
            apnsBroker.QueueNotification(new ApnsNotification
            
                DeviceToken = deviceToken,
                Payload= data

 );

            // Stop the broker, wait for it to finish   
            // This isn't done after every message, but after you're
            // done with the broker
           apnsBroker.Stop();
