awe*_*wef 5 python simplehttpserver
我真的很喜欢如何使用SimpleHTTPServer在网络上轻松共享文件,但我希望有一个选项,如"下载整个目录".是否有一种简单(单线程)的方式来实现这一点？
谢谢
看看源,例如在线这里.现在,如果您使用URL作为目录调用服务器,index.html则会提供其文件,或者缺少该文件的list_directory方法.大概,你想要zip用目录的内容(递归地,我想象)制作一个文件,并提供服务吗？显然没有办法用单行更改,因为你想要替换现在的68-80行(在方法中send_head)加上整个方法list_directory,第98-137行 - 这已经至少改变了50行;-).
如果你可以更改几十行,而不是一行,并且我所描述的语义是你想要的,你当然可以将所需的zipfile作为ZipFile类的cStringIO.StringIO对象构建,并用os填充它.walk在相关目录上(假设你想要递归地获取所有子目录).但它绝对不会是一个单线;-).
我为您做了修改，但我不知道是否有更好的方法可以做到，但是：
只需保存文件（例如：ThreadedHTTPServer.py）并以以下方式访问：
$ python -m /path/to/ThreadedHTTPServer PORT
修改也以线程方式工作，因此您不会在下载和导航的同时遇到问题，代码没有组织，但是：
