[Python-Dev] Allow custom headers in `http.server`

[Alex Yursha]

Hi CPython maintainers,

I need to test my CORS setup and looking for a possibility to set a custom Access-Control-Allow-Origin header in http.server. As of now, there is no such feature. Are you interested in me writing a patch to contribute a feature of setting custom headers directly to `http.server`?

Best,
- Alex

Hello.

This mailing list is to work on developing Python (adding new
features to Python itself and fixing bugs); if you're having problems
learning, understanding or using Python, please find another forum.
Probably python-list/comp.lang.python mailing list/news group is the
best place; there are Python developers who participate in it; you may
get a faster, and probably more complete, answer there. See
https://www.python.org/community/ for other lists/news groups/fora.
Thank you for understanding.

You can override method ``send_headers`` of the class
``HTTPRequestHandler`` and add your own headers. See an example at

https://docs.aws.amazon.com/polly/latest/dg/example-Python-server-code.html

Is this not something you can do yourself by calling send_header() after calling send_response()?

I thought about adding it as a command line option when invoked as `python3 -m http.server`.

Since this involves a potential suggested change (adding a feature to assign custom headers to http.server), python-ideas or the "Ideas" section of https://discuss.python.org/ would also be appropriate.
