Method Detail

getRealRequest

public static javax.servlet.http.HttpServletRequest getRealRequest(javax.servlet.http.HttpServletRequest request)

Return the request that the system should be dealing with, given the request that the browse just sent. If the incoming request is from a redirect resulting from successful authentication, a request object corresponding to the original request that prompted authentication is returned. Otherwise, the request passed in is returned.

Parameters:

request - the incoming HTTP request

Returns:

the HTTP request the DSpace system should deal with

resumeInterruptedRequest

public static void resumeInterruptedRequest(javax.servlet.http.HttpServletRequest request,
                                            javax.servlet.http.HttpServletResponse response)
                                     throws IOException

Resume a previously interrupted request. This is invoked when a user has been successfully authenticated. The request which led to authentication will be resumed.

Parameters:

request - current HTTP request

response - HTTP response

Throws:

IOException

startAuthentication

public static boolean startAuthentication(Context context,
                                          javax.servlet.http.HttpServletRequest request,
                                          javax.servlet.http.HttpServletResponse response)
                                   throws javax.servlet.ServletException,
                                          IOException

Start the authentication process. This packages up the request that led to authentication being required, and then invokes the site-specific authentication method. If it returns true, the user was authenticated without any redirection (e.g. by an X.509 certificate or other implicit method) so the process that called this can continue and send its own response. A "false" result means this method has sent its own redirect.

Parameters:

context - current DSpace context

request - current HTTP request - the one that prompted authentication

response - current HTTP response

Returns:

true if authentication is already finished (implicit method)

Throws:

javax.servlet.ServletException

IOException

loggedIn

public static void loggedIn(Context context,
                            javax.servlet.http.HttpServletRequest request,
                            EPerson eperson)

Store information about the current user in the request and context

Parameters:

context - DSpace context

request - HTTP request

eperson - the eperson logged in

loggedOut

public static void loggedOut(Context context,
                             javax.servlet.http.HttpServletRequest request)

Log the user out

Parameters:

context - DSpace context

request - HTTP request
