本篇实现的作用是利用Jinja2模板根据需要生成html 页面。
ghtml.py内容如下：
# cat ghtml.py
#!/usr/bin/env python
# coding=utf-8
# code from www.361way.com
import os
from jinja2 import Environment, FileSystemLoader
PATH = os.path.dirname(os.path.abspath(__file__))
TEMPLATE_ENVIRONMENT = Environment(
autoescape=False,
loader=FileSystemLoader(os.path.join(PATH, 'templates')),
trim_blocks=False)
def render_template(template_filename, context):
return TEMPLATE_ENVIRONMENT.get_template(template_filename).render(context)
def create_index_html():
fname = "output.html"
urls = ['http://www.361way.com/tag/python', 'http://www.361way.com/tag/linux', 'http://www.361way.com/tag/mysql']
context = {
'urls': urls
}
#
with open(fname, 'w') as f:
html = render_template('index.html', context)
f.write(html)
def main():
create_index_html()
########################################
if __name__ == "__main__":
main()templates/index.html模板内容如下：
# cat templates/index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>generating html</title>
</head>
<body>
<center>
<h1>generating html</h1>
<p>{{ urls|length }} links</p>
</center>
<ol align="left">
{% for url in urls -%}
<li><a href="{{ url }}">{{ url }}</a></li>
{% endfor -%}
</ol>
</body>
</html>执行后生成的内容如下：
# cat output.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>generating html</title>
</head>
<body>
<center>
<h1>generating html</h1>
