GNOME Online Accounts - Single sign-on framework for GNOME

==========================================================

Facebook

--------

OAuth 2.0:

https://developers.facebook.com/docs/authentication/

https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow

https://developers.facebook.com/docs/reference/dialogs/oauth/

https://developers.facebook.com/tools/explorer/

Scopes: https://developers.facebook.com/docs/authentication/permissions/

Notes:

The client-side flow returns the access_token and expires_in in the URI's

fragment, and does not provide a refresh_token. However, if the user denied

access then the error is returned in the URI's query. The URIs look like this:

  - <get_redirect_uri>?#access_token=...

  - <get_redirect_uri>?error=access_denied...#_=_

Sometimes the documentation does not mention the OAuth2 scopes that need to be

specified in the source code. In such cases, the following can be useful:

We are allowed to embed the client_secret in the source code. See

Notes:

We do not need the client_secret because we are marked as a desktop or mobile

application, and we use https://login.live.com/oauth20_desktop.srf as the

redirect_uri.
