Method Details

processOAuthInteraction

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

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<GoogleAccessTokenContext>

Parameters:

httpRequest -

httpResponse -

Returns:

InteractionState with state of OAuth interaction

Throws:

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

OAuthException - in case of some other error, which may be specific for this OAuth processor (Details are available in error code) Caller should be able to handle at least OAuthExceptionCode.USER_DENIED_SCOPE which happens when user denied scope (authorization screen in web of given social network)

OAuthException

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:

Parameters:

httpRequest -

httpResponse -

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

Returns:

Throws:
