This is a PHP client library for the LibLynx Connect identity and access management API. The API allows a publisher to control access to electronic resources without being concerned about the method used, e.g. IP, Shibboleth, SAML, OpenID Connect etc.

This library is open source, but access to the API requires a commercial agreement with LibLynx - contact us at info@liblynx.com to discuss your requirements.

Install

Via Composer

$ composer require liblynx-llc/liblynx-connect-php

Setting API credentials

In order to use this, you will need an API client id and client secret from LibLynx. These can be passed to the API client in one of two ways

Set API credentials through environment variables

You can set the following environment variables to avoid placing credentials in your code

  • LIBLYNX_CLIENT_ID
  • LIBLYNX_CLIENT_SECRET

Set API credentials through code

Alternatively, you can set the credentials directly, e.g.

$liblynx=new Liblynx\Connect\Client;
$liblynx->setCredentials('your client id', 'your client secret');

Caching

To work as efficiently as possible, the client caches API responses such as the entrypoint resource. Any PSR-16 compatible cache can be used, for example symfony/cache

For testing, you could use the ArrayCache from symfony/cache - install as follows:

$ composer require symfony/cache

Then create and use an ArrayCache as follows

$cache=new \Symfony\Component\Cache\Simple\ArrayCache;
$liblynx->setCache($cache);

Diagnostic logging

Detailed information on API usage can be obtained by passing a PSR-3 compatible logger to the client. This package includes a useful DiagnosticLogger class which can be used to store logs and then output them for console or HTML reading.

$logger = new \LibLynx\Connect\DiagnosticLogger;
$liblynx->setLogger($logger);

Examples

A simple integration involves obtaining an account from data provided in the current request superglobals

try {
    $identification = $liblynx->authorize(IdentificationRequest::fromArray($_SERVER));
    if ($identification->isIdentified()) {
        //visitor is identified, you can now check their access rights
    } elseif ($identification->requiresWAYF()) {
         //to find our who the visitor is, redirect to WAYF page
         $url = $identification->getWayfUrl();
         header("Location: $url");
         exit;
    } else {
        //liblynx failed - check diagnostic logs
    }
} catch (LibLynx\Connect\Exception\LibLynxException $e) {
    //exceptions are throw for API failures and erroneous integrations
    throw $e;
}    

See the examples folder for other examples:

  • examples\example.php is a console application which prompts for an IP and URL performs an identification.
