tornado框架之路二

二、路由系统

路由系统其实就是 url 和 类 的对应关系，这里不同于其他框架，其他很多框架均是 url 对应 函数，Tornado中每个url对应的是一个类。

#!/usr/bin/env python

import tornado.ioloop
import tornado.web

  
class MainHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Hello, world")



class WorkHanlder(tornado.web.RequestHandler): 
    def get(self,page): 
　　　　　self.write(page)


class StoryHandler(tornado.web.RequestHandler):
    def get(self, story_id):
        self.write("You requested the story " + story_id)


class BuyHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("buy.wupeiqi.com/index")
   

application = tornado.web.Application([
    (r"/index", MainHandler),
    (r"/story/([0-9]+)", StoryHandler),
　　 (r"/work/(?P<page>\d*)",WorkHanlder),
])


application.add_handlers('buy.wupeiqi.com$', [
    (r'/index',BuyHandler),
])

  
if __name__ == "__main__":
    application.listen(80)
    tornado.ioloop.IOLoop.instance().start()

分页（一页显示五条内容，每页显示11个页码）

if __name__ == "__main__":
    application.listen(8888)
