Example usage of AX in PHP OpenID

Question

I\'m using JanRain\'s PHP OpenID library. It comes with example script which is using SReg extension. But I want it to work with Google (and it works for auth actually), but

Answer 1

Ran into the same issue. Some digging in AX.php got me a working start. Haven't looked for any bugs, nor tested beyond basic, nor tested with anyone other than Google. This is not pretty: needs error handling, etc. But this should get you started. Will post an update if I have something robust...

First to throw ...

//  oid_request.php

// Just tested this with/for Google, needs trying with others ...
$oid_identifier = 'https://www.google.com/accounts/o8/id';

// Includes required files
require_once "Auth/OpenID/Consumer.php";
require_once "Auth/OpenID/FileStore.php";
require_once "Auth/OpenID/AX.php";

// Starts session (needed for YADIS)
session_start();

// Create file storage area for OpenID data
$store = new Auth_OpenID_FileStore('./oid_store');

// Create OpenID consumer
$consumer = new Auth_OpenID_Consumer($store);

// Create an authentication request to the OpenID provider
$auth = $consumer->begin($oid_identifier);

// Create attribute request object
// See http://code.google.com/apis/accounts/docs/OpenID.html#Parameters for parameters
// Usage: make($type_uri, $count=1, $required=false, $alias=null)
$attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/contact/email',2,1, 'email');
$attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/first',1,1, 'firstname');
$attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/last',1,1, 'lastname');

// Create AX fetch request
$ax = new Auth_OpenID_AX_FetchRequest;

// Add attributes to AX fetch request
foreach($attribute as $attr){
    $ax->add($attr);
}

// Add AX fetch request to authentication request
$auth->addExtension($ax);

// Redirect to OpenID provider for authentication
$url = $auth->redirectURL('http://localhost:4001', 'http://localhost:4001/oid_catch.php');
header('Location: ' . $url);

... and then to catch

<?php

//  oid_catch.php

// Includes required files
require_once "Auth/OpenID/Consumer.php";
require_once "Auth/OpenID/FileStore.php";
require_once "Auth/OpenID/AX.php";

// Starts session (needed for YADIS)
session_start();

// Create file storage area for OpenID data
$store = new Auth_OpenID_FileStore('./oid_store');

// Create OpenID consumer
$consumer = new Auth_OpenID_Consumer($store);

// Create an authentication request to the OpenID provider
$auth = $consumer->complete('http://localhost:4001/oid_catch.php');

if ($response->status == Auth_OpenID_SUCCESS) {
    // Get registration informations
    $ax = new Auth_OpenID_AX_FetchResponse();
    $obj = $ax->fromSuccessResponse($response);

    // Print me raw
    echo '<pre>';
    print_r($obj->data);
    echo '</pre>';
    exit;


} else {
  // Failed
}

Those ought to be the basics...

Answer 2

The request half is working, however I am getting failure in the Catch.

Should the line above

$auth = $consumer->complete('http://localhost:4001/oid_catch.php');

be

$response = $consumer->complete('http://localhost:4001/oid_catch.php');

Otherwise, where does the response object come from? I am not getting returned the openid.current_url in my response to check the url with?
