This article mainly introduces the use of Python to implement a simple upload download HTTP server, is the basis of Python network programming learning, this article is based on Windows operating system implementation, the need for friends can refer to the following

Introduction: This is a lightweight file sharing server written in Python (based on the built-in SimpleHTTPServer module),
Support file upload and download, as long as you have installed python (recommended version 2.6 ~ 2.7, does not support 3.x),
Then go to the directory you want to share and execute:
python SimpleHTTPServerWithUpload.py 1234
Where 1234 is the port number you specified, if not written, the default is 8080
Then visit http: // localhost: 1234, localhost or 1234 please replace as appropriate.

"" "Simple HTTP Server With Upload.
This module builds on BaseHTTPServer by implementing the standard GET
and HEAD requests in a fairly straightforward manner.

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,
Since Windows does not support certain netty low-level APIs, this code can only be run under Linux:
