這是一個采用Ruby實現的HTML5 Web Socket 服務器/客戶端。

* 如何運行示例


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"



使用示例

服務器:
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
客戶端:
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)

提示: JavaScript 客戶端實現

Google Chrome Dev Channel 原生支持 Web Socket. 對于其它瀏覽器，你可以使用一個Flash實現代替:http://github.com/gimite/web-socket-js/tree/master</pre>
