This module provide the OpenID interface for the SWI-Prolog website. If
you want to run this for local installations, make sure that your server
is accessible through the public network and first direct your browser
to the public network. Logging in using Google should work than. Some
other providers have more strict requirements.
You can fake OpenID login using the debug interface:
- grant(+User, +Token) is det
- revoke(+User, +Token) is det
- Grant/revoke User (a UUID) the right to access Token.
- authenticate(+Request, +Token, -Fields)
- Get authentication for editing wiki pages. This now first tries
the OpenID login.
- site_user(+Request, -User)
- Demand the user to be logged on and, if this is the first logon,
verify the user and create a profile.
- site_user_logged_in(-User) is semidet
- True when User is logged on. Does not try to logon the user.
- Create a link to the profile of a user.
- yadis:xrds_specified_location(+Server, -XRDSLocation)[multifile]
- Hacks to deal with broken Yadis support.
- Google does not support Yadis discovery, but does have an
XRSD document, so we fake its location.
- stackexchange.com serves an OP Identifier Element instead
of an Claimed Identifier Element when doing Yadis
discovery on the real OpenID.
- google_client:login_existing_user(+Claim) is semidet[multifile]
- True if the user is know to us and thus we can perform the login
without further interaction.
- google_client:create_user(+Profile) is det[multifile]
- Create a new user for the given Google Profile.
- Create a link to login, which returns to the current page.
- Redirect a request to the master server, so we do not have to
deal with multiple versions of the database files.
The following predicates are exported, but not or incorrectly documented.
- current_user(Arg1, Arg2, Arg3)
- revoke(Arg1, Arg2)
- site_user_property(Arg1, Arg2)
