web-socket-rubyWeb Socket 的 Ruby 实现

这是 Ruby 对 WebSocket 的实现，示例代码：

  # 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
