python2 -m SimpleHTTPServer
还有mongoose这是一个软件，是轻量的。
这两个都是web服务器，也就是可以单方向地传一些文件与信息。
应用一：当局域下有两台电脑，一台上开了一个网页，要在另了一台电脑上开同一个网页，可以保存这一个网页后开启web服务器
应用二：可以在另一个设置上用支持http的流媒体看一这台电脑上的视频。实验发现，SimpleHTTPServer对于流媒体不支持，反正不能正常工作。

Droopy
这是web的文件传输工作，运行这个，可以让别人给你传文件,在我路由下速度可达２５０Ｋ
Droopy is a mini Web server whose sole purpose is to let others upload files to your computer.
Does it work on my computer ?
You can use it on Unix (Linux, BSD, MacOSX) and Windows. Droopy is a python script so you’ll need to have Python installed.
How to use it ?
Note: A tutorial on how to set up Droopy on Windows was very kindly written by Ronan. The rest of this section focuses on Linux and MacOSX.
Droopy is a command-line program. I’ll suppose you’ve downloaded and saved the file in ~/bin/. Go to the directory where you want the uploaded files to be stored, for example:
mkdir ~/uploads
cd ~/uploads
Then, run droopy. You can give a message and a picture to display:
python ~/bin/droopy -m "Hi, it's me Bob. You can send me a file." -p ~/avatar.png
And it’s up and running on port 8000 of you computer. Check it out at http://localhost:8000, and give your computer’s address to your friends.
Type droopy -h to see all options:
Usage: droopy [options] [PORT]
