NAME¶
CGI::Application::Plugin::Authentication::Display - Generate bits of HTML needed
for authentication
VERSION¶
This document describes CGI::Application::Plugin::Authentication::Display
version 0.20
DESCRIPTION¶
The purpose of this code is to keep display code away from the back-end of
authentication management. It is an abstract base class and must be used in
conjunction with derived classes. Those derived classes can be used in an
number of ways:
- •
- The subclass CGI::Application::Plugin::Authentication::Display::Classic is
provided to ensure backwards compatibility with the old code. It has the
advantage of working out of the box but still retaining flexibility.
- •
- The subclass CGI::Application::Plugin::Authentication::Display::Basic is
provided to ensure XHTML compliance and to leave styling to CSS
style-sheets.
- •
- You can handle all the HTML side yourself in which case this code is not
even loaded.
- •
- You can use derived classes in templates that have dot support, which
keeps the display code close to the templates. This has other advantages.
For example one can use the "enforce_protection" method to mark
a template as being only viewable after authentication. A number of other
methods can be called from the template that provide information about the
authentication status.
METHODS¶
new¶
The constructor must be passed the CGI::Application object as the first
non-object argument. This allows derived modules to access the authentication
information.
login_box¶
This method will return the HTML for a login box that can be embedded into
another page. This is the same login box that is used in the default
authen_login runmode that the plugin provides.
This function is not implemented in this module. One must use a derived class
with an appropriate implementation of this function.
This returns the simple bit of HTML need to have a logout button. The form has
'/?authen_logout=1' as the action but of course this can be changed in derived
modules.
enforce_protection¶
This method is useful when the class is being used in templates to mark a
certain template as for authenticated eyes only. So in
HTML::Template::Plugin::Dot one might have
<TMPL_VAR NAME="authen.enforce_protection">
and one must set "authen" to one of these objects via the
"HTML::Template::param" method. If authenticated it will resolve to
a simple string, otherwise it will croak.
login_title¶
This returns the
TITLE parameter from the
LOGIN_FORM section of
the config.
is_authenticated¶
username¶
last_login¶
last_access¶
is_login_timeout¶
login_attempts¶
These methods all provide access to the cognate methods on the authentication
object. They are provided as templates might find them expressive.
BUGS¶
This is alpha software and as such, the features and interface are subject to
