How to exclude a controller action from authentica

Question

I'm trying to find a way so that one specific action in controller is excluded from auth and made public.

I need this to be done for API integration purposes.

Is there a place I could look at to change or include any functions to do this?

Below is what I have in Bootstrap.php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initAutoload()
    {
        $moduleLoader = new Zend_Application_Module_Autoloader(array(
            'namespace' => '',
            'basePath' => APPLICATION_PATH));

        $options = array(
            'layout'     => 'layout',
            'layoutPath' => APPLICATION_PATH.'/views/layouts/',
        );

        $layout = Zend_Layout::startMvc($options);

        return $moduleLoader;
    }


}

Answer 1

use a plugin that extends Zend_Controller_Plugin_Abstract and then in the plugin code

public function preDispatch(Zend_Controller_Request_Abstract $request)
    {
        $controller = $request->controller;
        $action = $request->action;
        if (strtolower($controller) == 'zona' && strtolower($action) == 'xml')
            {
                return ;
                }
        else
        {
        //check auth
        }
}

This is how i do my ACL controller plugin that has roles + resources where resources are combos of {{module}}_{{controller}} => array({{actions}})

<?php
class My_Controller_Plugin_Acl extends Zend_Controller_Plugin_Abstract
{
    public function preDispatch(Zend_Controller_Request_Abstract $request)
    {
        // set up acl
        $obj_acl = new Zend_Acl();

        // add the roles
    $obj_acl->addRole(new Zend_Acl_Role('guest'));
    $obj_acl->addRole(new Zend_Acl_Role('member'), 'guest');
    $obj_acl->addRole(new Zend_Acl_Role('admin'), 'member');

        // define all role/resource/actions
        $arr_role_resources = array(
            // role     => array of resources
            'guest'     => array(
                'default_index'                             => array('index', 'about-us', 'testimonials', 'interns', 'staff', 'contact-us'),
                'default_error'                             => array('error', 'denied'),
                'default_account'                           => array('index', 'login', 'register', 'logout', 'forgot-password'),
                'store_index'                               => array('index'),
                'store_category'                            => array('index', 'list', 'view'),
                'store_search'                          => array('index', 'results',),

                'store-admin_index'                     => array('login')
            ),
            'member'        => array(
                'default_account'                           => array('index', 'me', 'update', 'change-password', 'orders', 'view-order'),
            ),
            'admin' => array(
                'store-admin_index'                     => array('index'),
