[New-bugs-announce] [issue37666] urllib.requests.urlopen doesn't support cadata=

[Gregory P. Smith]

New submission from Gregory P. Smith <greg at krypto.org>:

The underlying https://docs.python.org/3/library/ssl.html#ssl.SSLContext.load_verify_locations API supports cafile, capath and cadata.

urlopen() only offers up cafile and capath.  It should also support cadata for completeness.

This matters for applications that embed their root certificate pem as data.  Requiring the user to write that to a file or ship that as a file just so the library can read it rather than passing it in as a string is gross.

Lets add cadata support to urlopen().
