PushSharp v4.0

PushSharp is a server-side library for sending Push Notifications to iOS/OSX (APNS), Android/Chrome (GCM/FCM), Windows/Windows Phone, Amazon (ADM) and Blackberry devices!

PushSharp v3.0+ is a complete rewrite of the original library, aimed at taking advantage of things like async/await, HttpClient, and generally a better infrastructure using lessons learned from the old code.

PushSharp will now follow semver versioning, so major version numbers will go up as there are any breaking api changes.

Sample Usage

The API in v3.x+ series is quite different from 2.x. The goal is to simplify things and focus on the core functionality of the library, leaving things like constructing valid payloads up to the developer.

APNS Sample Usage

Here is an example of how you would send an APNS notification:

// Configuration (NOTE: .pfx can also be used here)
var config = new ApnsConfiguration (ApnsConfiguration.ApnsServerEnvironment.Sandbox, 
    "push-cert.p12", "push-cert-pwd");

// Create a new 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 notificationException) {

            // 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!");
};

// Start the broker
apnsBroker.Start ();

foreach (var deviceToken in MY_DEVICE_TOKENS) {
    // Queue a notification to send
    apnsBroker.QueueNotification (new ApnsNotification {
        DeviceToken = deviceToken,
        Payload = JObject.Parse ("{\"aps\":{\"badge\":7}}")
    });
}

// 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 ();

Apple Notification Payload

More information about the payload sent in the ApnsNotification object can be found here.

Apple APNS Feedback Service

For APNS you will also need to occasionally check with the feedback service to see if there are any expired device tokens you should no longer send notifications to. Here's an example of how you would do that:

var config = new ApnsConfiguration (
    ApnsConfiguration.ApnsServerEnvironment.Sandbox, 
    Settings.Instance.ApnsCertificateFile, 
    Settings.Instance.ApnsCertificatePassword);

var fbs = new FeedbackService (config);
fbs.FeedbackReceived += (string deviceToken, DateTime timestamp) => {
    // Remove the deviceToken from your database
    // timestamp is the time the token was reported as expired
};
fbs.Check ();

GCM/FCM Sample Usage

Here is how you would send a GCM/FCM Notification:

// Configuration GCM (use this section for GCM)
var config = new GcmConfiguration ("GCM-SENDER-ID", "AUTH-TOKEN", null);
var provider = "GCM";

// Configuration FCM (use this section for FCM)
// var config = new GcmConfiguration("APIKEY");
// config.GcmUrl = "https://fcm.googleapis.com/fcm/send";
// var provider = "FCM";

// Create a new broker
var gcmBroker = new GcmServiceBroker (config);

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

    aggregateEx.Handle (ex => {

        // See what kind of exception it was to further diagnose
        if (ex is GcmNotificationException notificationException) {

            // Deal with the failed notification
            var gcmNotification = notificationException.Notification;
            var description = notificationException.Description;

            Console.WriteLine ($"{provider} Notification Failed: ID={gcmNotification.MessageId}, Desc={description}");
        } else if (ex is GcmMulticastResultException multicastException) {

            foreach (var succeededNotification in multicastException.Succeeded) {
                Console.WriteLine ($"{provider} Notification Succeeded: ID={succeededNotification.MessageId}");
            }

            foreach (var failedKvp in multicastException.Failed) {
                var n = failedKvp.Key;
                var e = failedKvp.Value;

                Console.WriteLine ($"{provider} Notification Failed: ID={n.MessageId}, Desc={e.Description}");
            }

        } else if (ex is DeviceSubscriptionExpiredException expiredException) {

            var oldId = expiredException.OldSubscriptionId;
            var newId = expiredException.NewSubscriptionId;

            Console.WriteLine ($"Device RegistrationId Expired: {oldId}");

            if (!string.IsNullOrWhiteSpace (newId)) {
                // If this value isn't null, our subscription changed and we should update our database
                Console.WriteLine ($"Device RegistrationId Changed To: {newId}");
            }
        } else if (ex is RetryAfterException retryException) {

            // If you get rate limited, you should stop sending messages until after the RetryAfterUtc date
            Console.WriteLine ($"{provider} Rate Limited, don't send more until after {retryException.RetryAfterUtc}");
        } else {
            Console.WriteLine ("{provider} Notification Failed for some unknown reason");
        }

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

gcmBroker.OnNotificationSucceeded += (notification) => {
    Console.WriteLine ("{provider} Notification Sent!");
};

// Start the broker
gcmBroker.Start ();

foreach (var regId in MY_REGISTRATION_IDS) {
    // Queue a notification to send
    gcmBroker.QueueNotification (new GcmNotification {
        RegistrationIds = new List<string> { 
            regId
        },
        Data = JObject.Parse ("{ \"somekey\" : \"somevalue\" }")
    });
}

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

Components of a GCM/FCM Notification

GCM notifications are much more customizable than Apple Push Notifications. More information about the messaging concepts and options can be found here.

WNS Sample Usage

Here's how to send WNS Notifications:

// Configuration
var config = new WnsConfiguration ("WNS_PACKAGE_NAME", "WNS_PACKAGE_SID", "WNS_CLIENT_SECRET");

// Create a new broker
var wnsBroker = new WnsServiceBroker (config);

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

    aggregateEx.Handle (ex => {

        // See what kind of exception it was to further diagnose
        if (ex is WnsNotificationException notificationException) {
            Console.WriteLine ($"WNS Notification Failed: {notificationException.Message}");
        } else {
            Console.WriteLine ("WNS Notification Failed for some (Unknown Reason)");
        }

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

wnsBroker.OnNotificationSucceeded += (notification) => {
    Console.WriteLine ("WNS Notification Sent!");
};

// Start the broker
wnsBroker.Start ();

foreach (var uri in MY_DEVICE_CHANNEL_URIS) {
    // Queue a notification to send
    wnsBroker.QueueNotification (new WnsToastNotification {
        ChannelUri = uri,
        Payload = XElement.Parse (@"
            <toast>
                <visual>
                    <binding template=""ToastText01"">
                        <text id=""1"">WNS_Send_Single</text>
                    </binding>  
                </visual>
            </toast>")
    });
}

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

How to Migrate from PushSharp 2.x to 3.x and higher

Please see this Wiki page for more information: https://github.com/Redth/PushSharp/wiki/Migrating-from-PushSharp-2.x-to-3.x

Roadmap

  • APNS - Apple Push Notification Service
    • Finish HTTP/2 support (currently in another branch)
  • GCM - Google Cloud Messaging
    • XMPP transport still under development
  • Other
    • More NUnit tests to be written, with a test GCM Server, and eventually Test servers for other platforms
    • New Xamarin Client samples (how to setup each platform as a push client) will be built and live in a separate repository to be less confusing
