如何在没有排队的情况下从C#发送APNS推送通知(iOS)

Question

似乎每个人都使用PushSharp从C#向iOS设备发送推送通知.但是该库有一个它使用的队列,而不是直接发送通知,这意味着您需要一个Windows服务或其他东西来正确托管它(根据自己的文档)这对我来说是过度的.我有一个传入Web请求到我的ASP.NET Web服务,作为处理它的一部分,我想立即发送推送通知.就那么简单.

任何人都可以告诉我如何使用PushSharp立即发送一个(绕过其队列机制)或如何正确发送推送通知自己？我已经有了制定JSON消息的代码,但我不知道如何将.p12文件应用于请求.我找不到任何Apple文档来说明如何做到这一点.

我花了很多时间试图找到一种推送通知的方法，然后我找到了一段可以帮我做到这一点的代码。

首先确保您正确安装了证书，这里有一个可以帮助您的链接。 https://arashnorouzi.wordpress.com/2011/04/13/sending-apple-push-notifications-in-asp-net-%E2%80%93-part-3-apns-certificates-registration-on-windows /

这是我用来推送通知的代码：

public static bool ConnectToAPNS(string deviceId, string message)
    {
        X509Certificate2Collection certs = new X509Certificate2Collection();

        // Add the Apple cert to our collection
        certs.Add(getServerCert());

        // Apple development server address
        string apsHost;
        /*
        if (getServerCert().ToString().Contains("Production"))
            apsHost = "gateway.push.apple.com";
        else*/
        apsHost = "gateway.sandbox.push.apple.com";

        // Create a TCP socket connection to the Apple server on port 2195
        TcpClient tcpClient = new TcpClient(apsHost, 2195);

        // Create a new SSL stream over the connection
        SslStream sslStream1 = new SslStream(tcpClient.GetStream());

        // Authenticate using the Apple cert
        sslStream1.AuthenticateAsClient(apsHost, certs, SslProtocols.Default, false);

        PushMessage(deviceId, message, sslStream1);

        return true;
    }

private static X509Certificate getServerCert()
    {
        X509Certificate test = new X509Certificate();

        //Open the cert store on local machine
        X509Store store = new X509Store(StoreLocation.CurrentUser);

        if (store != null)
        {
            // store exists, so open it and search through the certs for the Apple Cert
            store.Open(OpenFlags.ReadOnly);
            X509Certificate2Collection certs = store.Certificates;

            if (certs.Count > 0)
            {
                int i;
                for (i = 0; i < certs.Count; i++)
                {
                    X509Certificate2 cert = certs[i];

                    if (cert.FriendlyName.Contains("Apple Development IOS Push Services"))
                    {
                        //Cert found, so return it.
                        Console.WriteLine("Found It!");
                        return certs[i];
                    }
                }
            }
            return test;
        }
        return test;
    }

private static byte[] HexToData(string hexString)
    {
        if (hexString == null)
            return null;

        if (hexString.Length % 2 == 1)
            hexString = '0' + hexString; // Up to you whether to pad the first or last byte

        byte[] data = new byte[hexString.Length / 2];

        for (int i = 0; i < data.Length; i++)
            data[i] = Convert.ToByte(hexString.Substring(i * 2, 2), 16);

        return data;
    }

请注意，此代码用于开发证书“Apple Development IOS Push Services”。
