"""
  简介:这是一个 python 写的轻量级的文件共享服务器(基于内置的SimpleHTTPServer模块),
  支持文件上传下载,只要你安装了python(建议版本2.6~2.7,不支持3.x),
  然后去到想要共享的目录下,执行:
    python SimpleHTTPServerWithUpload.py 1234    
  其中1234为你指定的端口号,如不写,默认为 8000
  然后访问 http://localhost:1234 即可,localhost 或者 1234 请酌情替换。

"""Simple HTTP Server With Upload.

将以上代码保存为文件SimpleHTTPServerWithUpload.py,可以放到PYTHONPATH中直接以模块方式调用,如下所示:

python -m SimpleHTTPServerWithUpload 8888

或者放到任意目录,以脚本方式运行,如下:

python SimpleHTTPServerWithUpload.py 8888

说明:

python自带了一个SimpleHTTPServer也可以直接使用,不过上述版本支持上传功能,不光可以作为httpserver用来调试程序,还可以用于上传共享文件,甚是方便。不过性能略差,作为调试或者内部使用足矣。
