《Introduction to Tornado》笔记04-tornado框架模板的操作-模板渲染+模板继承+静态文件与模板文件目录配置

简单的模板操作见这篇博客

使用tornado实现简单的模板渲染程序

模板继承与静态文件的引用等综合的例子看这个 *****

目录结构如下

—— static目录存放静态的css与js文件

——templates目录存放程序的模板文件：base.html是母版文件，index.html继承自这个母版文件

—— app.py是tornado的启动文件

模板文件如下

base.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>{{ page_title }}</title>
    <link rel="stylesheet" href="{{ static_url('css/style.css') }}" />
</head>
<body>
<div id="container">
    <header>
        {% block header %}<h1>Burt's Books</h1>{% end %}
    </header>
    <div id="main">
        <div id="content">
            {% block body %}{% end %}
        </div>
    </div>
    <footer>
        {% block footer %}
        <p>

        </p>
        {% end %}
    </footer>
</div>

<script src="{{ static_url('js/script.js') }}"></script>
</body>
</html>

index.html

{% extends "base.html" %}

{% block header %}
<h1>{{ header_text }}</h1>
{% end %}

{% block body %}
<div id="hello">
    <p>Welcome to Burt's Books!</p>
    <p>...</p>
</div>
{% end %}

app.py文件如下

import tornado.web
import tornado.httpserver
import tornado.ioloop
import tornado.options
import os.path
from tornado.options import define, options

define("port", default=8014, help="run on the given port", type=int)


class MainHandler(tornado.web.RequestHandler):

    def get(self):
        self.render(
            "index.html",
            page_title="Burt's Books | Home",
            header_text="Welcome to Burt's Books!",
        )


class Application(tornado.web.Application):

    def __init__(self):
        handlers = [
            (r"/", MainHandler),
        ]
        settings = dict(
            template_path=os.path.join(os.path.dirname(__file__),"templates"),
            static_path=os.path.join(os.path.dirname(__file__), "static"),
            debug=True,
        )
        # 执行父类中的__init__方法，super或者下面的方法
        super().__init__(handlers,**settings)
        # tornado.web.Application.__init__(self, handlers, **settings)


if __name__ == "__main__":
    # 命令行方式启动tornado程序
    tornado.options.parse_command_line()

    # 讲Application类实例化的对象传进去
    http_server = tornado.httpserver.HTTPServer(Application())

    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()
