const gchar *
goa_oauth_provider_get_request_uri (GoaOAuthProvider *provider);

http://tools.ietf.org/html/rfc5849section-2.1

This is a pure virtual method - a subclass must provide an implementation.

goa_oauth_provider_get_request_uri_params ()

goa_oauth_provider_get_request_uri_params
                               (GoaOAuthProvider *provider);

Gets additional parameters for the request URI.

http://tools.ietf.org/html/rfc5849section-2.1

This is a virtual method where the default implementation returns NULL.

goa_oauth_provider_get_authorization_uri ()

const gchar *
goa_oauth_provider_get_authorization_uri
                               (GoaOAuthProvider *provider);

Gets the authorization uri.

http://tools.ietf.org/html/rfc5849section-2.2

This is a pure virtual method - a subclass must provide an implementation.

const gchar *
goa_oauth_provider_get_token_uri (GoaOAuthProvider *provider);

Gets the token uri.

http://tools.ietf.org/html/rfc5849section-2.3

This is a pure virtual method - a subclass must provide an implementation.

goa_oauth_provider_get_callback_uri ()

const gchar *
goa_oauth_provider_get_callback_uri (GoaOAuthProvider *provider);

Gets the callback uri.

http://tools.ietf.org/html/rfc5849section-2.1

This is a pure virtual method - a subclass must provide an implementation.

goa_oauth_provider_get_consumer_key ()

const gchar *
goa_oauth_provider_get_consumer_key (GoaOAuthProvider *provider);

Gets the consumer key identifying the client.

This is a pure virtual method - a subclass must provide an implementation.

goa_oauth_provider_get_consumer_secret ()

const gchar *
goa_oauth_provider_get_consumer_secret
                               (GoaOAuthProvider *provider);

Gets the consumer secret identifying the client.

This is a pure virtual method - a subclass must provide an implementation.

goa_oauth_provider_build_authorization_uri ()

gchar *
goa_oauth_provider_build_authorization_uri
                               (GoaOAuthProvider *provider,
                                const gchar *authorization_uri,
                                const gchar *escaped_oauth_token);

Builds the URI that can be opened in a web browser (or embedded web browser widget) to start authenticating an user.

The default implementation just returns the expected URI (e.g. http://example.com/dialog/oauth?auth_token=1234567890)

The authorization_uri parameter originate from the result of the the goa_oauth_provider_get_authorization_uri() method. The escaped_oauth_token parameter is the temporary credentials identifier escaped using g_uri_escape_string().

goa_oauth_provider_get_use_mobile_browser ()

gboolean
goa_oauth_provider_get_use_mobile_browser
                               (GoaOAuthProvider *provider);

Returns whether there is a need for the embedded browser to identify itself as running on a mobile phone in order to get a more compact version of the approval page.

This is a virtual method where the default implementation returns FALSE.

goa_oauth_provider_is_deny_node ()

gboolean
goa_oauth_provider_is_deny_node (GoaOAuthProvider *provider,
                                 WebKitDOMNode *node);

Checks whether node is the HTML UI element that the user can use to deny permission to access his account. Usually they are either a WebKitDOMHTMLButtonElement or a WebKitDOMHTMLInputElement.

Please note that providers may have multiple such elements in their UI and this method should catch all of them.

This is a virtual method where the default implementation returns FALSE.

goa_oauth_provider_is_identity_node ()

gboolean
goa_oauth_provider_is_identity_node (GoaOAuthProvider *provider,
                                     WebKitDOMHTMLInputElement *element);

Checks whether element is the HTML UI element that the user can use to identify herself at the provider.

This is a pure virtual method - a subclass must provide an implementation.

goa_oauth_provider_is_password_node ()

gboolean
goa_oauth_provider_is_password_node (GoaOAuthProvider *provider,
                                     WebKitDOMHTMLInputElement *element);

Checks whether element is the HTML UI element that the user can use to enter her password. This can be used to offer a GoaPasswordBased interface by saving the user's password. Providers usually frown upon doing this, so this is not recommended.

This is a virtual method where the default implementation returns FALSE.

goa_oauth_provider_add_account_key_values ()

void
goa_oauth_provider_add_account_key_values
                               (GoaOAuthProvider *provider,
                                GVariantBuilder *builder);

Hook for implementations to add key/value pairs to the key-file when creating an account.

This is a virtual method where the default implementation does nothing.

goa_oauth_provider_get_identity_sync ()

gchar *
goa_oauth_provider_get_identity_sync (GoaOAuthProvider *provider,
                                      const gchar *access_token,
                                      const gchar *access_token_secret,
                                      gchar **out_presentation_identity,
                                      GCancellable *cancellable,
                                      GError **error);

Method that returns the identity corresponding to access_token and access_token_secret .

The identity is needed because all authentication happens out of band. In addition to the identity, an implementation also returns a presentation identity that is more suitable for presentation (the identity could be a GUID for example).

The calling thread is blocked while the identity is obtained.

This is a pure virtual method - a subclass must provide an implementation.

goa_oauth_provider_get_access_token_sync ()

gchar *
goa_oauth_provider_get_access_token_sync
                               (GoaOAuthProvider *provider,
                                GoaObject *object,
                                gboolean force_refresh,
                                gchar **out_access_token_secret,
                                gint *out_access_token_expires_in,
                                GCancellable *cancellable,
                                GError **error);

Synchronously gets an access token for object . The calling thread is blocked while the operation is pending.

The resulting token is typically read from the local cache so most of the time only a local roundtrip to the storage for the token cache (e.g. gnome-keyring-daemon) is needed. However, the operation may involve refreshing the token with the service provider so a full network round-trip may be needed.

Note that multiple calls are serialized to avoid multiple outstanding requests to the service provider.

This operation may fail if e.g. unable to refresh the credentials or if network connectivity is not available. Note that even if a token is returned, the returned token isn't guaranteed to work - use goa_provider_ensure_credentials_sync() if you need stronger guarantees.

goa_oauth_provider_parse_request_token_error ()

gchar *
goa_oauth_provider_parse_request_token_error
                               (GoaOAuthProvider *provider,
                                RestProxyCall *call);

Tries to parse the headers and payload within call to provide a human readable error message in case the request token could not be fetched.

This is a pure virtual method - a subclass must provide an implementation.
