Method Details

processOAuthInteraction

public InteractionState<FacebookAccessTokenContext> processOAuthInteraction(jakarta.servlet.http.HttpServletRequest httpRequest,
 jakarta.servlet.http.HttpServletResponse httpResponse,
 String scope)
                                                                     throws IOException

Description copied from interface: OAuthProviderProcessor

Possibility to create new OAuth interaction with custom scope (not just the scope which is provided in configuration of this OAuth processor)

Specified by:

processOAuthInteraction in interface OAuthProviderProcessor<FacebookAccessTokenContext>

Parameters:

httpRequest -

httpResponse -

scope - custom scope, which contains all scopes in single String divided by AccessTokenContext.DELIMITER

Returns:

Throws:

IOException

processOAuthInteraction

public InteractionState<FacebookAccessTokenContext> processOAuthInteraction(jakarta.servlet.http.HttpServletRequest httpRequest,
 jakarta.servlet.http.HttpServletResponse httpResponse)
                                                                     throws IOException

Description copied from interface: OAuthProviderProcessor

Process OAuth workflow for this OAuth provider (social network). Workflow is finished if returned InteractionState is in state InteractionState.State.FINISH and in this case, InteractionState should also have accessToken filled. If InteractionState is in state InteractionState.State.AUTH, then more redirections are needed. In this case, given HttpServletResponse should be already committed and prepared for redirection.

Specified by:

processOAuthInteraction in interface OAuthProviderProcessor<FacebookAccessTokenContext>

Parameters:

httpRequest -

httpResponse -

Returns:

InteractionState with state of OAuth interaction

Throws:

IOException - if IO error occured (for example if httpResponse.sendRedirect failed)

processOAuthInteractionImpl

protected InteractionState<FacebookAccessTokenContext> processOAuthInteractionImpl(jakarta.servlet.http.HttpServletRequest httpRequest,
 jakarta.servlet.http.HttpServletResponse httpResponse,
 FacebookProcessor facebookProcessor)
                                                                            throws IOException

Throws:

IOException

getPrincipal

public FacebookPrincipal getPrincipal(FacebookAccessTokenContext accessTokenContext)

Description copied from interface: GateInFacebookProcessor

Obtain informations about user from Facebook and wrap them into FacebookPrincipal object

Specified by:

getPrincipal in interface GateInFacebookProcessor

Parameters:

accessTokenContext - Facebook access token

Returns:

FacebookPrincipal

getAvatar

public String getAvatar(FacebookAccessTokenContext accessTokenContext)

Specified by:

getAvatar in interface GateInFacebookProcessor

saveAccessTokenAttributesToUserProfile

public void saveAccessTokenAttributesToUserProfile(org.exoplatform.services.organization.UserProfile userProfile,
 OAuthCodec codec,
 FacebookAccessTokenContext accessTokenContext)

Description copied from interface: OAuthProviderProcessor

Save accessToken data to given userProfile. Note that we are not calling any DB save operations, just filling data into given userProfile

Specified by:

saveAccessTokenAttributesToUserProfile in interface OAuthProviderProcessor<FacebookAccessTokenContext>

Parameters:

userProfile - where data about access token will be filled

codec - to encode some attributes (sensitive data) before save them to user profile

accessTokenContext - specific access token for this OAuth processor

Parameters:

userProfile - where data from access token will be obtained

codec - to decode data from userProfile

Returns:

accesstoken or null if accessToken is not found in persistent storage

removeAccessTokenFromUserProfile

public void removeAccessTokenFromUserProfile(org.exoplatform.services.organization.UserProfile userProfile)

Description copied from interface: OAuthProviderProcessor
