web-socket-ruby 介绍
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
