For a test suite I need to create a local SSL-enabled HTTPS server in my Python project. I googled around and found various recipes using pyOpenSSL, but all of those are quite complicated, and I didn’t even get the referenced one to work.
Also, Python has shipped its own built-in SSL module for quite a while. After reading some docs and playing around, I eventually got it to work with a remarkably simple piece of code using the builtin
from http.server import HTTPServer, SimpleHTTPRequestHandler import ssl context = ssl.SSLContext(ssl.PROTOCOL_TLS_SERVER) context.load_cert_chain(certfile='/tmp/cert.pem', keyfile='/tmp/key.pem') context.check_hostname = False with HTTPServer(("localhost", 4443), SimpleHTTPRequestHandler) as httpd: httpd.socket = context.wrap_socket(httpd.socket, server_side=True) httpd.serve_forever()
(I use port 4443 so that I can run the tests as normal user; the usual port 443 requires root privileges).
Way to go, Python!
