web文件管理器有很多，基于asp、php等语言，由于需要经常从电脑上下载文件，没有其他ftp、php环境，只安装了python，于是用tornado写了一个文件管理器。

功能说明：

读取电脑所有盘符下的文件
只有下载功能
文本修改功能待增加

核心代码：

#coding=utf-8
from tornado import web,httpserver,ioloop
import os
import base64
import random
import time,datetime
import tornado.options


tornado.options.define("root", default='')
tornado.options.define("pswd", default='')
tornado.options.pswd = ''
tornado.options.pwd = '123'
tornado.options.html = '''<html>

tornado.options.upload = '''<html>

}

# 路由
application = web.Application([

if __name__ == '__main__':
	http_server = httpserver.HTTPServer(application)
	# 监听端口
	http_server.listen(8080)
	#print('http://127.0.0.1:8080/')
	ioloop.IOLoop.current().start()

效果如下：
