PRG Pattern sample for me

app.py

import tornado.ioloop
import tornado.web
from jinja2 import Environment, FileSystemLoader


class MainHandler(tornado.web.RequestHandler):
    def get(self):
        env = Environment(loader=FileSystemLoader('./', encoding='utf8'))
        template = env.get_template('./login.html')
        self.write(template.render())


class RegisterHandler(tornado.web.RequestHandler):
    def post(self):
        # 登録処理
        self.redirect(r"/thanks")


class ThanksHandler(tornado.web.RequestHandler):
    def get(self):
        self.write("Thanks!!")


def make_app():
    return tornado.web.Application([
        (r"/", MainHandler),
        (r"/register", RegisterHandler),
        (r"/thanks", ThanksHandler),
    ])


if __name__ == "__main__":
    app = make_app()
    app.listen(8888)
    tornado.ioloop.IOLoop.current().start()
