The general idea of the patch is that a denied ws upgrade should better
understand that it logically stays as http on both sides. It's
specifically aimed at failed ws upgrade case only.
The patch is making a failed ws upgrade negotiation response act just
like a http client getting an http response from the server.
So IIUI what you're asking is "how do I read http client bodies".

The minimal-http-client example does what you want. For example
$ ./bin/lws-minimal-http-client --path /git/noexist
goes to https://libwebsockets.org/git/noexist which blows a 403
Forbidden (libwebsockets.org itself is configured to return a valid page
for 404s with styles, /git is actually a reverse proxy to an instance of
gitohashi which will return a 403 for that suitable for this test).
If you enable this in the example
https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/http-client/minimal-http-client-attach/minimal-http-client-attach.c#n54
you will see the client example is dumping
[2020/03/09 06:37:37:7771] U: Connected to 46.105.127.147, http
response: 403
