好吧，表示单单输出一句话，好像没什么难度，并且显示也很丑。

那就使用模版吧。一听模版是不是瞬间感觉高大上了。（偷笑中）

现在开始！

poemmaker.py

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')
        verb = self.get_argument('verb')
        noun3 = self.get_argument('noun3')
        self.render('poem.html', roads=noun1, wood=noun2, made=verb,
                difference=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()

再来一个模版index.html

<!DOCTYPE html>
<html>
    <head><title>Poem Maker Pro</title></head>
    <body>
        <h1>Enter terms below.</h1>
        <form method="post" action="/poem">
        <p>Plural noun<br><input type="text" name="noun1"></p>
        <p>Singular noun<br><input type="text" name="noun2"></p>
        <p>Verb (past tense)<br><input type="text" name="verb"></p>
        <p>Noun<br><input type="text" name="noun3"></p>
        <input type="submit">
        </form>
    </body>
</html>

poem.html

<!DOCTYPE html>
<html>
    <head><title>Poem Maker Pro</title></head>
    <body>
        <h1>Your poem</h1>
        <p>Two {{roads}} diverged in a {{wood}}, and I—<br>
I took the one less travelled by,<br>
And that has {{made}} all the {{difference}}.</p>
    </body>
</html>
