HTML5 Web Socket server/client implementation in Ruby. For server, em-websocket ( https://github.com/igrigorik/em-websocket ) may be a better choice, especially if you want to use EventMachine. * How to run sample - Run sample Web Socket server (echo server) with: $ ruby samples/echo_server.rb localhost 10081 - Run sample Web Socket client and type something: $ ruby samples/stdio_client.rb ws://localhost:10081 Ready hoge Sent: "hoge" Received: "hoge" * Usage example Server: # Runs the server at port 10081. It allows connections whose origin is example.com. server = WebSocketServer.new(:port => 10081, :accepted_domains => ["example.com"]) server.run() do |ws| # The block is called for each connection. # Checks requested path. if ws.path == "/" # Call ws.handshake() without argument first. ws.handshake() # Receives one message from the client as String. while data = ws.receive() puts(data) # Sends the message to the client. ws.send(data) end else # You can call ws.handshake() with argument to return error status. ws.handshake("404 Not Found") end end Client: # Connects to Web Socket server at host example.com port 10081. client = WebSocket.new("ws://example.com:10081/") # Sends a message to the server. client.send("Hello") # Receives a message from the server. data = client.receive() puts(data) * Supported WebSocket protocol versions WebSocketServer class (server) accepts version hixie-75, hixie-76, hybi-07, hybi-10. WebSocket class (client) speaks version hixie-76. * Tips: JavaScript client implementation Google Chrome Dev Channel natively supports Web Socket. For other browsers, you can use an implementation using Flash: http://github.com/gimite/web-socket-js/tree/master * WebSocket protocol versions The server supports the protocol defined in RFC 6455, draft versions hixie-75 and hixie-76. The client speaks draft version hixie-76. * License New BSD License.
