作为很多地方都介绍过的，python自带的SimpleHTTPServer，只需要一个命令就可成为一个web服务器，可以实现文件的共享（下载）功能。 一个命令：python -m SimpleHTTPServer 默认就会监听0.0.0.0:8000，其输出信息中有 “Serving HTTP on 0.0.0.0 port 8000”等。 然后，用浏览器打开 http://server_ip:8000/ 的 URL 即可看到一个web页面展示着启动的目录下各个文件。 当然，你想换个端口（假设8888），命令改一下即可：python -m SimpleHTTPServer 8888 不过，原生的SimpleHTTPServer不支持文件的上传；因为有时候，不想给用户名密码给别人，但就临时想让同事传个文件到某服务器上，那么就可以考虑引入下面这个 SimpleHTTPServerWithUpload.py 代码见：https://github.com/smilejay/python/blob/master/py2016/SimpleHTTPServerWithUpload.py 使用方法：python SimpleHTTPServerWithUpload.py 也可以加上8888这样的端口号。 然后浏览器中的web页面的上方就有选择文件并上传的功能（upload），之后是目录中文件的列表可供下载（download）。 使用起来还是很方便的，临时需求可以用用。 代码实际来源：https://github.com/tualatrix/tools/blob/master/SimpleHTTPServerWithUpload.py #!/usr/bin/env python """Simple HTTP Server With Upload. https://github.com/tualatrix/tools/blob/master/SimpleHTTPServerWithUpload.py This module builds on BaseHTTPServer by implementing the standard GET and HEAD requests in a fairly straightforward manner.
