README

(This package is a fork of rask/openid-connect-php.)

A simple library that allows an application to authenticate a user through the basic OpenID Connect flow. This library hopes to encourage OpenID Connect use by making it simple enough for a developer with little knowledge of the OpenID Connect protocol to setup authentication.

A special thanks goes to Justin Richer and Amanda Anganes for their help and support of the protocol.

This package was originally created by Michael Jett and extensively modified by Otto Rask.

Requirements

PHP 5.4 or greater
CURL extension
JSON extension

Install

Install library using composer

composer require kdoyen/openid-connect-php

Then include composer autoloader

<?php

require '/vendor/autoload.php';

Example 1: Basic Client

<?php

use OpenIdConnectClient\OpenIdConnectClient;

$oidc = new OpenIDConnectClient([
        'provider_url' => 'https://id.provider.com/',
        'client_id' => 'ClientIDHere',
        'client_secret' => 'ClientSecretHere'
    ]);

$oidc->authenticate();
$name = $oidc->requestUserInfo('given_name');

See openid spec for available user attributes.

Example 2: Dynamic Registration

<?php

use OpenIdConnectClient\OpenIdConnectClient;

$oidc = new OpenIDConnectClient([
        'provider_url' => 'https://id.provider.com/'
    ]);

$oidc->register();
$client_id = $oidc->getClientID();
$client_secret = $oidc->getClientSecret();

Be sure to add logic to store the client id and client secret inside your application.

Example 3: Network and Security

<?php

// Configure a proxy
$oidc->setHttpProxy('http://my.proxy.com:80/');

// Configure a cert
$oidc->setCertPath('/path/to/my.cert');

Example 4: Request Client Credentials Token

<?php

use OpenIdConnectClient\OpenIdConnectClient;

$oidc = new OpenIDConnectClient([
        'provider_url' => 'https://id.provider.com/',
        'client_id' => 'ClientIDHere',
        'client_secret' => 'ClientSecretHere'
    ]);

$oidc->providerConfigParam([
    'token_endpoint' => 'https://id.provider.com/connect/token'
]);

$oidc->addScope('my_scope');

// This assumes success (to validate check if the access_token
// property is there and a valid JWT):
$clientCredentialsToken = $oidc->requestClientCredentialsToken()->access_token;

Example 5: Token Introspection

<?php

use OpenIdConnectClient\OpenIdConnectClient;

$oidc = new OpenIDConnectClient([
        'provider_url' => 'https://id.provider.com/',
        'client_id' => 'ClientIDHere',
        'client_secret' => 'ClientSecretHere'
    ]);

// Provide access token to introspect.
// Can take an optional second parameter to set the token_type_hint.
$introspectionResponse = $oidc->introspectToken('provided_access_token');

// Check if the response/token is active and valid (based on exp and nbf).
$introspectionResponse->isActive();

// Get a list of allowed scopes.
$scopeArray = $introspectionResponse->getScopes();

// Simple boolean response if response has scope provided.
$introspectionResponse->hasScope('profile');

Todo

Dynamic registration does not support registration auth tokens and endpoints.
