Fleck is a WebSocket server implementation in C#. Branched from the Nugget project, Fleck requires no inheritance, container, or additional references.
The following is an example that will echo to a client.
var server = new WebSocketServer("ws://localhost:8181");
server.Start(socket =>
{
socket.OnOpen = () => Console.WriteLine("Open!");
socket.OnClose = () => Console.WriteLine("Close!");
socket.OnMessage = message => socket.Send(message);
});
Fleck supports several WebSocket versions of modern web browsers
- Hixie-Draft-76/Hybi-00 (Safari 5, Chrome < 14, Firefox 4 (when enabled))
- Hybi-07 (Firefox 6)
- Hybi-10 (Chrome 14-16, Firefox 7)
- Hybi-13 (Chrome 17+)
Enabling secure connections requires two things: using the scheme wss instead
of ws, and pointing Fleck to an x509 certificate containing a public and
private key
var server = new WebSocketServer("wss://localhost:8431");
server.Certificate = new X509Certificate2("MyCert.pfx");
server.Start(socket =>
{
//...use as normal
});To enable negotiation of subprotocols, specify the supported protocols on
the WebSocketServer.SupportedSubProtocols property. The negotiated
subprotocol will be available on the socket's ConnectionInfo.NegotiatedSubProtocol.
If no supported subprotocols are found on the client request (the Sec-WebSocket-Protocol header), the connection will be closed.
var server = new WebSocketServer("ws://localhost:8181");
server.SupportedSubProtocols = new []{ "superchat", "chat" };
server.Start(socket =>
{
//socket.ConnectionInfo.NegotiatedSubProtocol is populated
