Thanks @nstansby -- you're right, a second NopCloser not needed since you can just log the message as you've demonstrated above, then create just the one NopCloser for r.Body to continue on.

Mine was mainly a quick paste-in for debugging, so I didn't invest too much time in it.

Yours is nicer and could be used for debugging or production logging. Thanks again for adding your improvements!
