Redirect to login from Action

[jonathan doklovic, modifié il y a 13 années.]

Hi,

I have a portlet that has multiple actions.
One of these actions is linked to from guest available page, but requires an authenticated user.

How can I check if the user is logged in, and if not, redirect to login and have it redirect back to the action with the original parameters? Again, I need to do this from within and action, not a jsp.

Thanks.

Check the isSignedIn() method in ThemeDisplay.java. You have to get the user first either through PotalUtil object or ThemeDisplay object and then you can check if user is signed in and get required information.

Thanks

Easy enough to get the user, but if not logged in, how do i do the redirect properly to the login form and have it redirect back?

You may want to take a look at portal/action/LoginAction.java

Probably do something like this:

PortletURL portletURL = new PortletURLImpl(
request, PortletKeys.LOGIN, themeDisplay.getPlid(),
PortletRequest.RENDER_PHASE);

portletURL.setWindowState(WindowState.MAXIMIZED);
portletURL.setPortletMode(PortletMode.VIEW);

portletURL.setParameter("saveLastPath", "0");
portletURL.setParameter("struts_action", "/login/login");
portletURL.setParameter("redirect", [currentURL])

response.sendRedirect(redirect);

HI Amos,

i followed the same approach for redirection, but i m getting error like can not find symbol for PortletURLImpl.

i had imported the foll for PortletURLImpl.

import com.sun.portal.portletcontainer.portlet.impl.PortletURLImpl;

Plz suggest where i m getting deviated to error.

PortletURLImpl isn't accessible from plugins. Try this instead:

<%
LiferayPortletURL liferayPortletURL = PortletURLFactoryUtil.create(request, PortletKeys.LOGIN, themeDisplay.getPlid(), PortletRequest.RENDER_PHASE);

liferayPortletURL.setWindowState(WindowState.MAXIMIZED);
liferayPortletURL.setPortletMode(PortletMode.VIEW);

liferayPortletURL.setParameter("saveLastPath", "0");
liferayPortletURL.setParameter("struts_action", "/login/login");
liferayPortletURL.setParameter("redirect", PortalUtil.getCurrentURL(request));
%>

Hi everyone,

I intend to create my own login portlet. I got the authentication by using UserLocalServiceUtil.authenticateByEmailAddress (UserLocalServiceUtil.authenticateByScreenName)and put my login information to Session & Cookie (Just like LoginUtil in liferay) but I can't find the way to get in portal with my acc that i do the authentication. Are there something wrong or i'm missing something ? Please help T_T
I'm newbie so I use MVC Portlet not Struts Portlet

Thanks in advanced,
Tam Nguyen
