Mvc-Auth-Token implementation for zend framework 2

This module will take care of HTTP Token authentication as described in the draft-hammer-http-token-auth-01. It should be used with zf-mvc-auth.

The purpose of this module is to provide an extendable interface for validating Tokens. The validation of the Token should be done in a custom adapter.

Query params

In some situations, it is not possible to add the Authentication header to the request. Therefor the token parameters can also be added as query parameters:

http://yourserver.local/endpoint
    ?token[realm]=realm
    &token[token]=token
    &token[coverage]=coverage
    &token[nonce]=nonce
    &token[timestamp]=timestamp
    &token[auth]=auth

Note: This part of the authentication is not in the official draft, but could be useful in some situations.

Installation

curl -s https://getcomposer.org/installer | php
php composer.phar install

Module Installation

Add to composer.json

"phpro/zf-mvc-auth-token": "dev-master"

Add module to application.config.php

return array(
    'modules' => array(
        'Phpro\MvcAuthToken',
        // other libs...
    ),
    // Other config
);

Add a new listener and adapter in your module 'module.config.php'

return array(
    'service_manager' => array(
        'invokables' => array(
            'YourModule\Authentication\Adapter\TokenAdapter' => 'YourModule\Authentication\Adapter\TokenAdapter',
        )
    ),
    'mvc-auth-token-authentication-listener' => array(
        'YourModule\Authentication\Listener\TokenListener' => array(
            'adapter' => 'YourModule\Authentication\Adapter\TokenAdapter',
        ),
    ),
);

*Note: * The listener is not an actual class. The AbstractAuthenticationListener will create an AuthenticationListener for you, which is configured with your custom adapter.

Add a TokenAdapter class to your Module.

e.g. YourModule\Authentication\Adapter\TokenAdapter

This custom class will implement the AdapterInterface and should be used to validate your token:

class YourModule\Authentication\Adapter\TokenAdapter 
    implements \Phpro\MvcAuthToken\Adapter\AdapterInterface
{
    // Implement your own Token Adapter logica
}

Add a new listener in your Module::onBootstrap

Now the last step is to add your configured AuthenticationListener to the MvcAuthEvent. When the Authentication event is triggered, your listener will handle Token Authorization.

/**
 * @param MvcEvent $e
 */
public function onBootstrap(MvcEvent $e)
{
    $app      = $e->getApplication();
    $events   = $app->getEventManager();
    $services = $app->getServiceManager();

    $events->attach(MvcAuthEvent::EVENT_AUTHENTICATION, $services->get('YourModule\Authentication\Listener\TokenListener'), 1000);
}

Note: Make sure that the priority is above the current zf-mvc-auth authentication priority.

How to retrieve the authenticated user?

/** @var \Zend\Authentication\AuthenticationService $authentication */
$authentication = $serviceLocator->get('authentication');
$identity = $authentication->getIdentity();
