This is a .NET library for interacting with the Pusher REST API.

Registering at http://pusher.com and use the application credentials within your app as shown below.

Comprehensive documenation can be found at http://pusher.com/docs/.

This is a 2.0.0 BETA version. Version 1.3 with the previous API can be found here .

Install-Package PusherServer -Pre

The latest 2.0.0 BETA can be found here: http://cl.ly/3E1a472Z1I30/pusher-dotnet-server-2.0.0-beta.2.zip

var Pusher = new Pusher(APP_ID, APP_KEY, APP_SECRET);

To trigger an event on one or more channels use the trigger function.

var result = pusher.Trigger( "channel-1", "test_event", new { message = "hello world" } );

var result = pusher.Trigger( new string[]{ "channel-1", "channel-2" ], "test_event", new { message: "hello world" } );

In order to avoid the person that triggered the event also receiving it the trigger function can take an optional ITriggerOptions parameter which has a SocketId property. For more informaiton see: http://pusher.com/docs/publisher_api_guide/publisher_excluding_recipients.

var result = pusher.Trigger(channel, event, data, new TriggerOptions() { SocketId = "1234.56" } );

To authorise your users to access private channels on Pusher, you can use the Authenticate function:

var auth = pusher.Authenticate( channelName, socketId );
var json = auth.ToJson();

The json can then be returned to the client which will then use it for validation of the subscription with Pusher.

For more information see: http://pusher.com/docs/authenticating_users

Using presence channels is similar to private channels, but you can specify extra data to identify that particular user:

var channelData = new PresenceChannelData() {
	user_id: "unique_user_id",
	user_info: new {
	  name = "Phil Leggetter"
	  twitter_id = "@leggetter"
	}
};
var auth = pusher.Authenticate( channelName, socketId, channelData );
var json = auth.ToJson();

The json can then be returned to the client which will then use it for validation of the subscription with Pusher.

For more information see: http://pusher.com/docs/authenticating_users

It is possible to query the state of your Pusher application using the generic Pusher.Get( resource ) method and overloads.

For full details see: http://pusher.com/docs/rest_api

You can get a list of channels that are present within your application:

IGetResult<ChannelsList> result = pusher.Get<ChannelsList>("/channels");

You can provide additional parameters to filter the list of channels that is returned.

IGetResult<ChannelsList> result = pusher.Get<ChannelsList>("/channels", new { filter_by_prefix = "presence-" } );

Retrive information about a single channel:

IGetResult<object> result = pusher.Get<object>("/channels/my_channel" );

Note: object has been used above because as yet there isn't a defined class that the information can be serialized on to

Retrive a list of users that are on a presence channel:

IGetResult<object> result = pusher.Get<object>("/channels/presence-channel/users" );

Note: object has been used above because as yet there isn't a defined class that the information can be serialized on to

• Developed using Visual Studio 2010 or Visual Studio 2012
• PusherServer acceptance tests presently need the PusherClient DLL. Eventually this will be changed to fetch via NuGet.

You should be familiar with creating an publishing NuGet packages.

From the pusher-dotnet-server directory:

1. Update pusher-dotnet-server.nuspec with new version number etc.
2. Run package.cmd
3. Run `tools/nuget.exe push Download/PusherServer.{VERSION}.nupkg'
