Use Python to implement a simple HTTP server that can be uploaded and downloaded

This article mainly introduces how to use Python to implement a simple HTTP server capable of uploading and downloading. it is the basis for learning Python network programming. This example is implemented based on the Windows operating system, for more information, see

1. httpserver
========================================================
This httpserver is a enhanced version of SimpleHTTPServer.
It was write in python, I use some code from bottle [https://github.com/defnull/bottle]
It support resuming download, you can set the document root, it has more
Friendly error hit, and it can handle mimetype gracefully

Https://github.com/lerry/httpserver/blob/master/httpserver.py

2. SimpleHTTPServer based on java netty,

Because windows does not support some netty low-level APIs, this code can only run in linux:
