您可以将目录树生成及其渲染分离为html.

要生成树,您可以使用简单的递归函数：

def make_tree(path):

tree = dict(name=os.path.basename(path), children=[])

try: lst = os.listdir(path)

except OSError:

pass #ignore errors

else:

for name in lst:

fn = os.path.join(path, name)

if os.path.isdir(fn):

tree['children'].append(make_tree(fn))

else:

tree['children'].append(dict(name=name))

return tree

为了将其呈现为HTML,您可以使用jinja2的循环递归特征：

Path: {{ tree.name }}

{{ tree.name }}

{%- for item in tree.children recursive %}

{{ item.name }}

{%- if item.children -%}

• {{ loop(item.children) }}

{%- endif %}

{%- endfor %}

要测试它,请访问http：// localhost：8888 /：

import os

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')

def dirtree():

path = os.path.expanduser(u'~')

return render_template('dirtree.html', tree=make_tree(path))

if __name__=="__main__":

app.run(host='localhost', port=8888, debug=True)
