Package TWiki::AccessControlException

Exception used raise an access control violation. This exception has the following fields:

  • web - the web which was being accessed
  • topic - the topic being accessed (if any)
  • user - canonical username of the person doing the accessing. Use the methods of the TWiki::Users class to get more information about the user.
  • mode - the access mode e.g. CHANGE, VIEW etc
  • reason a text string giving the reason for the refusal.

The exception may be thrown by plugins. If a plugin throws the exception, it will normally be caught and the browser redirected to a login screen (if the user is not logged in) or reported (if they are and just don't have access).

  • $mode - mode of access (view, change etc)
  • $user - canonical user name of user doing the accessing
  • $web - web being accessed
  • $topic - topic being accessed
  • $reason - string reason for failure

All the above fields are accessible from the object in a catch clause in the usual way e.g. $e->{web} and $e->{reason}
