Python编程语言很强大，能做出很多的工具供在不同环境下使用，今天介绍的python源码是：Python Tornado实现web实时消息聊天的方法源码。



tornado在Python语言的学习过程中会或多或少的接触一些。今天就来讲Tornado 实现实时消息聊天的方法，及源码下载。在网络上能找到很多类似这样的案例，我也参考着再写一次，当做练手了。



（1）代码用中到的前端是：

twitter 的项目 bootstrap

ajax 框架是 jquery



（2）Tornado实现web实时消息聊天基本原理和思路：

服务器端使用观察者模式，发现有消息更新，会第一时间调用所有监听点的 callback 函数； 网络方面用的是 tornado 的异步长连接，一直到收到 callback 才结束连接发出响应。-Python programming language is very powerful, able to make a lot of tools for use in different environments, today introduced python source code is: Python Tornado achieve real-time web chat message source method. tornado in the process of learning Python language will be more or less contact with some. Tornado method today in terms of real-time chat messages, and download the source code. On the network can find a lot of cases like this, I also refer to the write once, as a practiced hand. The front end (1) of the Code to be used: Project twitter bootstrap ajax framework is jquery (2) Tornado achieve instant messaging web chat basic principles and ideas: the server side using the Observer pattern, finds a message update, the first time to call callback function to listen to all points　networks using asynchronous tornado long connection until the callback received a response before the end of the connection.
