c#中的苹果推送通知提供商

Question

我对苹果推送通知服务完全陌生。我正在尝试为我的应用程序实现它。我在google和stackoverflow中搜索得很好，但并不满意。我正在尝试在c#中实现provider。我也尝试过MoonAPNs。

这里有没有人能给我推荐一步一步的教程，这很简单。我已经获得了ios开发人员证书和apn证书以及p12密钥。我需要你的帮助。提前谢谢。

Answer 1

下面是我正在使用的基础设施和流程：

简介:我使用PushSharp与APNS服务器进行通信。我有一个SQL Server后端数据库设置来处理所有订阅和发送的通知。我也有一个虚拟服务器(实际上是几个)，所有的.p12证书都被复制到它们上面。这些服务器具有进程，该进程检查表中需要发出的任何推送通知，然后将数据集传递给PushSharp进程。

详细规格:表1- APNS_Subscriptions

CREATE TABLE [dbo].[APNS_Subscriptions](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [DeviceToken] [varchar](250) NULL,
    [DeviceID] [varchar](250) NULL,
    [NetworkID] [varchar](250) NULL,
    [Application] [varchar](250) NULL,
    [AddedOn] [datetime] NULL,
    [Active] [bit] NULL,
    [Dev] [bit] NULL,
    [BadgeCount] [int] NOT NULL,
 CONSTRAINT [PK_APNSSubscriptions] PRIMARY KEY CLUSTERED 
(
    [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

表2- APNS_PushNotifications

CREATE TABLE [dbo].[APNS_PushNotifications](
    [id] [int] IDENTITY(1,1) NOT NULL,
    [DeviceToken] [varchar](250) NULL,
    [AlertMessage] [varchar](250) NULL,
    [BadgeNumber] [int] NULL,
    [SoundFile] [varchar](250) NULL,
    [ApplicationName] [varchar](250) NULL,
    [AddedOn] [datetime] NULL,
    [AddedBy] [varchar](250) NULL,
    [ProcessedOn] [datetime] NULL,
    [ViewedOnDeviceDateTime] [datetime] NULL,
 CONSTRAINT [PK_APNS_PushNotifications] PRIMARY KEY CLUSTERED 
(
    [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

我通过此SP添加订阅(通过实现APNS的每个iPhone应用程序通过app服务调用此SP：

这是从几个不同数据库中的几个不同位置调用的。执行ins_APNS_PushNote @NetworkID，@iOSApplicationName，@AlertMessage，@SoundFile，@RequestedBy

检索虚拟服务器(PushSharp)的以下APNS请求的SP：

[get_APNSToSend]
AS 
    BEGIN

        DECLARE @CurrentTimestamp AS DATETIME = CURRENT_TIMESTAMP

        UPDATE dbo.APNS_PushNotifications
        SET ProcessedOn = CURRENT_TIMESTAMP
        WHERE ProcessedOn IS NULL

        SELECT  id ,
                DeviceToken ,
                AlertMessage ,
                BadgeNumber ,
                SoundFile ,
                ai.APNSDistCertFile AS APNSCertFile
        FROM    dbo.APNS_PushNotifications apns
                INNER JOIN dbo.ApplicationInfo ai ON ai.ApplicationName = apns.ApplicationName
        WHERE   ProcessedOn = @CurrentTimestamp
                AND ai.APNSDistCertFile IS NOT NULL


    END 

现在来看我对PushSharp应用程序所做的更改。实际上可以归结为两个方法: static void Main(string[] args) { checkForPushRequest()；}

    static void checkForPushRequest()
    {
        string YourConnString = "YourConnectionStringToTheDBGoesHere";

            Stored_Procedure SP = new Stored_Procedure {
            Name = "get_APNSToSend",
            Parameters = new List<SqlParameter>()
        };

        try {
            System.Data.DataTable dt = DatabaseOperations.Execute_Database_Command(YourConnString, SP, true);

            if ((dt != null) && !(dt.Rows.Count < 1)) {
                foreach (System.Data.DataRow dRow in dt.Rows) {
                    string deviceToken = Convert.ToString(dRow[1]);
                    string alertMessage = Convert.ToString(dRow[2]);
                    int badgeNumber =  Convert.ToInt16(dRow[3]);
                    string soundFile = Convert.ToString(dRow[4]);
                    string apnsCertFileToUse = Convert.ToString(dRow[5]);
                    sendPush(deviceToken, alertMessage, soundFile, badgeNumber, apnsCertFileToUse);
                }
            }
        } catch (Exception ex) {
            // Handle your exception
        }
    }

    static void sendPush(string DeviceToken, string AlertMessage, string SoundFile, int BadgeNumber, string apnsCertFileToUse)
    {
        //Create our service    
        PushService push = new PushService();

        //Wire up the events
        push.Events.OnDeviceSubscriptionExpired += new PushSharp.Common.ChannelEvents.DeviceSubscriptionExpired(Events_OnDeviceSubscriptionExpired);
        //push.Events.OnDeviceSubscriptionIdChanged += new PushSharp.Common.ChannelEvents.DeviceSubscriptionIdChanged(Events_OnDeviceSubscriptionIdChanged);
        push.Events.OnChannelException += new PushSharp.Common.ChannelEvents.ChannelExceptionDelegate(Events_OnChannelException);
        push.Events.OnNotificationSendFailure += new PushSharp.Common.ChannelEvents.NotificationSendFailureDelegate(Events_OnNotificationSendFailure);
        push.Events.OnNotificationSent += new PushSharp.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!  
        //  This comes from the ApplicationInfo table.  Each app that supports APNS has it's own certfile name in the column
        string certFileToUse = "C:\\APNS_Certs\\" + apnsCertFileToUse;

        var appleCert = File.ReadAllBytes(certFileToUse);

        //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(false, appleCert, "P12PasswordHere"));

        //Fluent construction of an iOS notification
        //IMPORTANT: For iOS you MUST MUST MUST use your own DeviceToken here that gets generated within your iOS app itself when the Application Delegate
        //  for registered for remote notifications is called, and the device token is passed back to you
        push.QueueNotification(NotificationFactory.Apple()
            .ForDeviceToken(DeviceToken)
            .WithAlert(AlertMessage)
            .WithSound(SoundFile)
            .WithBadge(BadgeNumber));

        //Console.WriteLine("Waiting for Queue to Finish...");

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

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

我向PushSharp解决方案添加了一个控制台项目，并将控制台部署到APNS服务器。此控制台应用程序基于每分钟运行一次的计划任务触发。

如果你有更多的问题，请告诉我。在过去的一年里，我一直在企业环境中使用这个过程，没有遇到任何问题。工作完美无瑕。

Answer 2

在使用MoonAPNS时，我建议您阅读由库作者撰写的关于Sending Apple Push Notifications in ASP.NET and C#的4部分指南。

Answer 3

在C# web page.First中使用创建APNS推送通知以创建web应用程序并启动web表单。
