@mdonkers @amgodoi would you have an objection to set a FOSS license for your gist's code?

— to give more context, I'm assoc. professor in CS and if possible, I'd like to set a small assignment, reusing your PoC 😊

no objection @erikmd

@erikmd I wonder to what extend such simple code is licensable in the first place. But no objections. Hereby granting you (and everyone else) all the freedom to do with the code however you like.

OK thanks for your reply!

Awesome, thanks! Used in gist 36583dde8e0eb8e97e2cff2e7d9d2836

port

What host and port are you trying to run it on?

error when receiving the request result: headers responsible for the end of the data were not found

Thank you! This can be easily extended to handle https requests by adding
httpd.socket = ssl.wrap_socket(httpd.socket, server_side=True, keyfile="key.pem", certfile='cert.pem')
after line 36. However, ssl.wrap_socket() is deprecated. Does anyone know how to do this with SSLContext.wrap_socket()?

I tried with

context = ssl.create_default_context()
context.load_cert_chain(certfile='cert.pem', keyfile="key.pem")

but then context.wrap_socket(httpd.socket, server_side=True) complains about "check_hostname requires server_hostname". Adding a hostname, it complains that hostnames can only be used in client mode.

@maiphi any luck in getting the https to work ?

Seeing your question, I just looked into it again. This should do the job (note that I did only a very quick test):

context = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER)
context.load_cert_chain('cert.pem', 'key.pem')
httpd.socket = context.wrap_socket(httpd.socket, server_side=True)

Note that except for the deprecation warning the version using ssl.wrap_socket() works fine, too.
