Python Web Server

A Python web server as a docker container:

FROM python:3.10-slim

ENTRYPOINT ["python3", "-m", "http.server", "-d", "/path/to/webroot/", "8000"]

 

Upload via a HTTP form:

#/usr/bin/python
#
# HTTP server with a HTML form that allows to upload files to the server.
# Files are stored in a folder named "files" inside the current directory.

from os import curdir
from os.path import join as pjoin

from http.server import BaseHTTPRequestHandler, HTTPServer

from cgi import FieldStorage

<html><body>
<form enctype="multipart/form-data" method="post">
<p>File: <input type="file" name="file"></p>
<p><input type="submit" value="Upload"></p>
</form>
</body></html>
"""
