tornado简易聊天室

初学tornado，尝试写了一下简易聊天室。

class EchoHandler(tornado.websocket.WebSocketHandler):

users = set()

def check_origin(self, origin):

return True

def open(self):

self.users.add(self)

for u in self.users:

u.write_message('欢迎用户[%s]-[%s]' %(self.request.remote_ip,datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")))

@tornado.gen.coroutine

def on_message(self, message):

for u in self.users:

u.write_message(u"[%s]-[%s]-说:%s" % (self.request.remote_ip,datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S"),message))

def on_close(self):

self.users.remove(self)

for u in self.users:

u.write_message(u"[%s]-[%s]-离开了" % (self.request.remote_ip,datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")))

主要是借着websocket深层理解一下tornado的异步功能，写给以后的自己哈哈
