WebSocketProxy is a lightweight C# library which allows you to connect to an HTTP server and websocket server through the same TCP port. This library is independent on which web frameworks are used for handling websocket and http requests.
Installation can be done using NuGet.
Install-Package WebSocketProxy
The project "WebSocket.Sample" contains a sample usage using NancyFX and Fleck.
The first step is to build the configuration object in which you set the endpoints that are listening for HTTP (Nancy) and WebSocket requests (Fleck) and the public endpoint which will be listening to both kinds of requests.
TcpProxyConfiguration configuration = new TcpProxyConfiguration()
{
PublicHost = new Host()
{
IpAddress = IPAddress.Parse("0.0.0.0"),
Port = 8080
},
HttpHost = new Host()
{
IpAddress = IPAddress.Loopback,
Port = 8081
},
WebSocketHost = new Host()
{
IpAddress = IPAddress.Loopback,
Port = 8082
}
};Then, initialize Nancy and Fleck, followed by the WebSocketServer.
using (var nancyHost = new NancyHost(new Uri("http://localhost:8081")))
using (var websocketServer = new WebSocketServer("ws://0.0.0.0:8082"))
using (var tcpProxy = new TcpProxyServer(configuration))
{
// Initialize Nancy
nancyHost.Start();
// Initialize Fleck
websocketServer.Start(connection =>
{
connection.OnOpen = () => Console.WriteLine("Connection on open");
connection.OnClose = () => Console.WriteLine("Connection on close");
connection.OnMessage = message => Console.WriteLine("Message: " + message);
});
// Initialize the proxy
tcpProxy.Start();
Console.WriteLine("Press [Enter] to stop");
Console.ReadLine();
}By pointing the web browser to the port 8080, you will receive an html page which initializes a websocket connection.
This library supports HTTPS and WSS. Simply pass the certificate path and password in the configuration object and all incoming requests will be unencrypted and routed to the corresponding library.
