How to use Grails Spring Security Plugin to require logging in before access an action?
- by Hoàng Long
Hi all,
I know that I can use annotation or Request mapping to restrict access to an ACTION by some specific ROLES. But now I have a different circumstance.
My scenario is: every user of my site can create posts, and they can make their own post public, private, or only share to some other users. I implement sharing post by a database table PERMISSION, which specify if a user have the right to view a post or not.
The problem arises here is that when a customer access a post through a direct link, how can I determine he/she have the privilege to view it? There's 3 circumstances:
The post is public, so it can be viewed by anyone (include not-login
user)
The post is private, so only the login-owner can view it
The post is sharing, it means only the login-user that is shared and the
owner can view it.
I want to process like this:
If the requested post is public: ok.
If the requested post is private/sharing: I want to redirect
the customer to the login page; after
logging in, the user will be re-direct
to the page he wants to see.
The problem here is that I can redirect the user to login controller/ auth action, but after that I don't know how to redirect it back. The link to every post is different by post_id, so I can't use SpringSecurityUtils.securityConfig.successHandler.defaultTargetUrl
Could anyone know a way to do this?
