Detailed Description

OAuth service for Facebook as third-party authenticator.

The configuration of the service is done using properties, whose values need to match the values configured at Facebook.

For example:

<properties>
<property name="facebook-oauth2-redirect-endpoint">
http://localhost:8080/oauth2callback
</property>
<property name="facebook-oauth2-app-id">
1234567890123456
</property>
<property name="facebook-oauth2-app-secret">
a3cf1630b1ae415c7260d849efdf444d
</property>
</properties>

Like all service classes, this class holds only configuration state. Thus, once configured, it can be safely shared between multiple sessions since its state (the configuration) is read-only. A "const FacebookService" object is thus thread-safe.

Member Function Documentation

std::string Wt::Auth::FacebookService::authenticationScope ( ) const
virtual

Returns the scope needed for authentication.

This returns the scope that is needed (and sufficient) for obtaining identity information, and thus to authenticate the user.

See Also
OAuthProcess::getIdentity(), OAuthProcess::startAuthenticate()

Implements Wt::Auth::OAuthService.

std::string Wt::Auth::FacebookService::authorizationEndpoint ( ) const
virtual

Returns the authorization endpoint URL.

This is a remote URL which hosts the OAuth authorization user interface. This URL is loaded in the popup window at the start of an authorization process.

Implements Wt::Auth::OAuthService.

std::string Wt::Auth::FacebookService::clientId ( ) const
virtual

Returns the client ID.

This is the identification for this web application with the OAuth authorization server.

Implements Wt::Auth::OAuthService.

std::string Wt::Auth::FacebookService::clientSecret ( ) const
virtual

Returns the client secret.

This is the secret credentials for this web application with the OAuth authorization server.

Implements Wt::Auth::OAuthService.

bool Wt::Auth::FacebookService::configured ( )
static

Checks whether a FacebookAuth service is properly configured.

This returns true if a value is found for the three configuration properties.

OAuthProcess * Wt::Auth::FacebookService::createProcess ( const std::string &  scope) const
virtual

Creates a new authorizaiton process.

This creates a new authorization process for the indicated scope. Valid names for the scope are service provider dependent.

See Also
authenticationScope()

Implements Wt::Auth::OAuthService.

WString Wt::Auth::FacebookService::description ( ) const
virtual

Returns the provider description.

This returns a description useful for e.g. tool tips on a login icon.

See Also
name()

Implements Wt::Auth::OAuthService.

std::string Wt::Auth::FacebookService::name ( ) const
virtual

Returns the provider name.

This is a short identifier.

See Also
description()

Implements Wt::Auth::OAuthService.

int Wt::Auth::FacebookService::popupHeight ( ) const
virtual

Returns the desired height for the popup window.

See Also
popupWidth()

Implements Wt::Auth::OAuthService.

int Wt::Auth::FacebookService::popupWidth ( ) const
virtual

Returns the desired width for the popup window.

See Also
popupHeight()

Implements Wt::Auth::OAuthService.

std::string Wt::Auth::FacebookService::redirectEndpoint ( ) const
virtual

Returns the redirection endpoint URL.

This is the local URL to which the browser is redirect from the service provider, after the authorization process. You need to configure this URL with the third party authentication service.

A static resource will be deployed at this URL.

See Also
WServer::addResource()

Implements Wt::Auth::OAuthService.

std::string Wt::Auth::FacebookService::redirectEndpointPath ( ) const
virtual

Returns the deployment path of the redirection endpoint.

This returns the path at which the static resource is deployed that corresponds to the redirectEndpoint().

The default implementation will derive this path from the redirectEndpoint() URL.

Reimplemented from Wt::Auth::OAuthService.

std::string Wt::Auth::FacebookService::tokenEndpoint ( ) const
virtual

Returns the token endpoint URL.

This is a remote URL which hosts a web-service that generates access tokens.

Implements Wt::Auth::OAuthService.

Http::Method Wt::Auth::FacebookService::tokenRequestMethod ( ) const
virtual

Returns the HTTP method used for the token request.

While the current OAuth 2.0 draft mandates the use of POST, some implementations (like Facebook) use URL-encoding and a GET request.

The default implementation returns Http::Post (corresponding to the current draft).

Reimplemented from Wt::Auth::OAuthService.
