The oauth2 elpa package provides oauth2 authentication. The Oauth2
standard  works by passing around authentication tokens. The oauth2.el
appends the token to the url as a query parameter. This works with some
services, but the preferred way is to pass it in an
"Authorization: Bearer" header. Quote from RFC 6570:

    Because of the security weaknesses associated with the URI method
    (see Section 5), including the high likelihood that the URL
    containing the access token will be logged, it SHOULD NOT be used
    unless it is impossible to transport the access token in the
    "Authorization" request header field or the HTTP request entity-body.

oauth2.el should be able to use the header mechanism, either mandatory
or as a default.

My first attempt at dealing with this myself was unsuccessful. Is there 
an easy
way to log the http(s) requests that emacs sends, including headers?
(In url-http.el?) I found the buffers with the responses, but not the 
requests.
