想用SPRING MVC,NODE.JS EXPRESS,TORNADO实现同一个功能，开阔一下视野。
先来TORNADO的吧。。
客户端代码都差不多，主要是服务端代码。
TORNADO的说法：
http://www.tornadoweb.org/en/stable/websocket.html
Override on_message to handle incoming messages, and use write_message to send messages to the client. You can also override open and on_close to handle opened and closed connections.
websocket事件说法：
https://html.spec.whatwg.org/multipage/comms.html#network
服务端代码：
import tornado.webimport tornado.websocketimport tornado.httpserverimport tornado.ioloopclass WebSocketHandler(tornado.websocket.WebSocketHandler): def open(self): pass def on_message(self, message): self.write_message(u"Your message was: " + message) print message self.write_message(u"hahhahahah") def on_close(self): passclass IndexPageHandler(tornado.web.RequestHandler): def get(self): self.render("websockets.html")class Application(tornado.web.Application): def __init__(self): handlers = [ (r'/', IndexPageHandler), (r'/ws', WebSocketHandler) ] settings = { 'template_path': 'static' } tornado.web.Application.__init__(self, handlers, **settings)if __name__ == '__main__': ws_app = Application() server = tornado.httpserver.HTTPServer(ws_app) server.listen(8888) tornado.ioloop.IOLoop.instance().start() js代码：
Tornado WebSockets Message to Send:
