服務端代碼：

def new_client(client, server):
server.send_message_to_all("Hey all, a new client has joined us")
def mysend(client,server,msg):
print(msg)
server.send_message(client,"哈哈哈哈哈")
if(msg == "_end"): #如果收到了_end 消息，那麼斷開連接
server.server_close()
server = WebsocketServer(5005, host='127.0.0.1', loglevel=logging.INFO)
server.set_fn_new_client(new_client)
server.set_fn_message_received(mysend)
server.run_forever()
server.server_close()
if __name__ == "__main__":
startWebsocketServer()
