Tornado，展示一下模板渲染

按网上一步一步走一下。

感觉模板和DJANGO的差不多，但更灵活，不限制PYTHON的使用。

前端和后端，这模板使用的规则在哪里呢？

import os.path

import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web

from tornado.options import define, options
define("port", default=8000, help="run on the given port", type=int)

class IndexHandler(tornado.web.RequestHandler):
    def get(self):
        self.render('index.html')

class PoemPageHandler(tornado.web.RequestHandler):
    def post(self):
        noun1 = self.get_argument('noun1')
        noun2 = self.get_argument('noun2')
        noun3 = self.get_argument('noun3')
        verb = self.get_argument('verb')
        self.render('poem.html', roads=noun1, wood=noun2,
                    made=verb, defference=noun3)

if __name__ == "__main__":
    tornado.options.parse_command_line()
    app = tornado.web.Application(
        handlers=[
            (r"/", IndexHandler),
            (r"/poem", PoemPageHandler),
            ],
        template_path=os.path.join(os.path.dirname(__file__), "templates")
        )
    http_server = tornado.httpserver.HTTPServer(app)
    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()
