Hello. I'm a big fan of the http.server module to quickly serve some files in a local network with `python3 -m http.server`. I regularly needed to get some files from other people too, but getting everyone to install/run python3 was not such a simple task. Eventually I wrote a subclass of SimpleHTTPRequestHandler that added a form with a file input and accepted POST requests, so people could also upload files to my computer. I think this would be a fine addition to SimpleHTTPRequestHandler, so I'm attaching a potential patch that implements this and adds a new cli parameter so this feature is only enabled explicitly.

There is PEP 594 (draft), which - when accepted - will remove cgi.FieldStorage

https://www.python.org/dev/peps/pep-0594/

https://discuss.python.org/t/pep-594-removing-dead-batteries-from-the-standard-library/1704

This comes from an idea to relief the burden of maintenance for the maintainers.



Some off-topic comments...

cgi.FieldStorage has quite some unresolved issues, partially open for many years, although there are also some pull requests, waiting for review.

While cgi.FieldStorage is certainly a niche thing, it is used by Zope, by Plone, by webob... 

The latter even has a 250 line compat module to accomodate for current bugs ( https://github.com/Pylons/webob/blob/5c062aef9397b27915c5cc2ed2f202bff7494eca/src/webob/compat.py ).

If you, Javier, are also a fan of cgi.FieldStorage want to improve the situation with cgi.FieldStorage, maybe you could help reviewing the open issues and the open pull requests for cpython?

I see. To be honest I didn't know FieldStorage at all, it was the best way I found of dealing with file data in requests using just the standard library. If you think this feature makes sense and it could be included, I could look into removing the FieldStorage dependency.

Disclaimer: I am not cpython maintainer - I just wanted to give a bit of context for using `cgi.FieldStorage`.

Personally, I'd rather not include this in the std, but create a small package for PyPI. But that's only me.

Wait until you get feedback from a cpython maintainer.

I would find this very useful.
