ubuntu11.04(unix 就可以了) 共享文件以及支持上传文件

我这两个功能是分开实现的。。。

共享文件：

很简单，就一条命令:

python -m SimpleHTTPServer

如果要指定端口号直接在刚才的命令后面加上你要的端口号。接着别人就可以用你的IP访问了。（在哪个目录下使用这条命令就共享该文件夹）

支持上传文件：

首先建一个droop文件，写入以下代码（代码最后才列出），然后放到~/bin/目录下，接着敲下面的命令：

mkdir ~/uploads

cd ~/uploads

python -m "Hi, I am alfred! Here you can upload you file to me:)" -p ~/bin/mypicture

这样人家就可以根据你的ip访问了，以下是截图

droop的代码：
