Magento – Oauth Error while extending Magento Rest API

adminapiextensionsmagento-1.7oauth

I am working with Magento Rest API for the first time, i went through the tutorials of Rest API on http://www.magentocommerce.com/api/rest and tried one example to fetch product through API:

$callbackUrl = "http://localhost/wineshop/products.php";
$temporaryCredentialsRequestUrl = "http://localhost/wineshop/oauth/initiate?     oauth_callback=" . urlencode($callbackUrl);
$adminAuthorizationUrl = 'http://localhost/wineshop/admin/oauth_authorize';
$accessTokenRequestUrl = 'http://localhost/wineshop/oauth/token';
$apiUrl = 'http://localhost/wineshop/api/rest';
$consumerKey = 'u48p1x9gzrg7r82c94woa5z7g805uw0i';
$consumerSecret = '96ydrk8s89xxath8h5z71vcl5abfq0zg';

session_start();
if (!isset($_GET['oauth_token']) && isset($_SESSION['state']) && $_SESSION['state'] == 1) {
$_SESSION['state'] = 0;
}
try {
$authType = ($_SESSION['state'] == 2) ? OAUTH_AUTH_TYPE_AUTHORIZATION : OAUTH_AUTH_TYPE_URI;
$oauthClient = new OAuth($consumerKey, $consumerSecret,  OAUTH_SIG_METHOD_HMACSHA1, $authType);
$oauthClient->enableDebug();

I've also installed the latest version of OAUTH and it also shows in my WampServer PHP Extensions but it doesn't show in phpinfo(). I coped the php_oauth.dll file into ..\www\bin\php\ext and i also edited php.ini and entered extension=php_oauth.dll but on running the products.php it shows me the

Fatal error: Class 'OAuth' not found in P:\wamp\www\products.php on line 19

And i also want to know that how to request for the token i've got key and secret after entering new consumer in Magento Admin Panel. But i don't know how to get Access Token & Access Token Secret that we enter in RESTClient

Please Help, Thanks in advance

I can partially answer your question.

Access Token and Access Token secret are provided by the authentication server upon request and they validate the further requests.

Just a matter of chance, you can check if oAuth works for you by following this link

Magento – OAuth: How to add magento product using oauth rest api from external php script

If you have access to the admin account for the backend it will be very useful as admin will have the permission already set up for adding products to the system. Lets assume you have access to the admin user.

This is a sample code which will add a product to the system using OAuth as admin

<?php
/**
* Example of simple product POST using Admin account via Magento REST API. OAuth authorization is used
*/
$callbackUrl = "http://yourhost/oauth_admin.php";
$temporaryCredentialsRequestUrl = "http://magentohost/oauth/initiate?oauth_callback=" . urlencode($callbackUrl);
$adminAuthorizationUrl = 'http://magentohost/admin/oauth_authorize';
$accessTokenRequestUrl = 'http://magentohost/oauth/token';
$apiUrl = 'http://magentohost/api/rest';
$consumerKey = 'yourconsumerkey';
$consumerSecret = 'yourconsumersecret';

session_start();
if (!isset($_GET['oauth_token']) && isset($_SESSION['state']) && $_SESSION['state'] == 1) {
    $_SESSION['state'] = 0;
}
try {
    $authType = ($_SESSION['state'] == 2) ? OAUTH_AUTH_TYPE_AUTHORIZATION : OAUTH_AUTH_TYPE_URI;
    $oauthClient = new OAuth($consumerKey, $consumerSecret, OAUTH_SIG_METHOD_HMACSHA1, $authType);
    $oauthClient->enableDebug();

    if (!isset($_GET['oauth_token']) && !$_SESSION['state']) {
        $requestToken = $oauthClient->getRequestToken($temporaryCredentialsRequestUrl);
        $_SESSION['secret'] = $requestToken['oauth_token_secret'];
        $_SESSION['state'] = 1;
        header('Location: ' . $adminAuthorizationUrl . '?oauth_token=' . $requestToken['oauth_token']);
        exit;
    } else if ($_SESSION['state'] == 1) {
        $oauthClient->setToken($_GET['oauth_token'], $_SESSION['secret']);
        $accessToken = $oauthClient->getAccessToken($accessTokenRequestUrl);
        $_SESSION['state'] = 2;
        $_SESSION['token'] = $accessToken['oauth_token'];
        $_SESSION['secret'] = $accessToken['oauth_token_secret'];
        header('Location: ' . $callbackUrl);
        exit;
    } else {
        $oauthClient->setToken($_SESSION['token'], $_SESSION['secret']);
        $resourceUrl = "$apiUrl/products";
        $productData = json_encode(array(
            'type_id'           => 'simple',
            'attribute_set_id'  => 4,
            'sku'               => 'simple' . uniqid(),
            'weight'            => 1,
            'status'            => 1,
            'visibility'        => 4,
            'name'              => 'Simple Product',
            'description'       => 'Simple Description',
            'short_description' => 'Simple Short Description',
            'price'             => 99.95,
            'tax_class_id'      => 0,
        ));
        $headers = array('Content-Type' => 'application/json');
        $oauthClient->fetch($resourceUrl, $productData, OAUTH_HTTP_METHOD_POST, $headers);
        print_r($oauthClient->getLastResponseInfo());
    }
} catch (OAuthException $e) {
    print_r($e);
}

This code snippet is courtesy of Magento REST api documentation. Link here

Magento – OAuth for REST API using PHP

The documentation on Magento's site has a good example here

Here's one of the examples that they give for creating a simple product as an Admin user with OAuth authentication.

session_start();
if (!isset($_GET['oauth_token']) && isset($_SESSION['state']) && $_SESSION['state'] == 1) {
$_SESSION['state'] = 0;
}
try {
$authType = ($_SESSION['state'] == 2) ? OAUTH_AUTH_TYPE_AUTHORIZATION : OAUTH_AUTH_TYPE_URI;
$oauthClient = new OAuth($consumerKey, $consumerSecret, OAUTH_SIG_METHOD_HMACSHA1, $authType);
$oauthClient->enableDebug();

if (!isset($_GET['oauth_token']) && !$_SESSION['state']) {
    $requestToken = $oauthClient->getRequestToken($temporaryCredentialsRequestUrl);
    $_SESSION['secret'] = $requestToken['oauth_token_secret'];
    $_SESSION['state'] = 1;
    header('Location: ' . $adminAuthorizationUrl . '?oauth_token=' . $requestToken['oauth_token']);
    exit;
} else if ($_SESSION['state'] == 1) {
    $oauthClient->setToken($_GET['oauth_token'], $_SESSION['secret']);
    $accessToken = $oauthClient->getAccessToken($accessTokenRequestUrl);
    $_SESSION['state'] = 2;
    $_SESSION['token'] = $accessToken['oauth_token'];
    $_SESSION['secret'] = $accessToken['oauth_token_secret'];
    header('Location: ' . $callbackUrl);
    exit;
} else {
    $oauthClient->setToken($_SESSION['token'], $_SESSION['secret']);
    $resourceUrl = "$apiUrl/products";
    $productData = json_encode(array(
        'type_id'           => 'simple',
        'attribute_set_id'  => 4,
        'sku'               => 'simple' . uniqid(),
        'weight'            => 1,
        'status'            => 1,
        'visibility'        => 4,
        'name'              => 'Simple Product',
        'description'       => 'Simple Description',
        'short_description' => 'Simple Short Description',
        'price'             => 99.95,
        'tax_class_id'      => 0,
    ));
    $headers = array('Content-Type' => 'application/json');
    $oauthClient->fetch($resourceUrl, $productData, OAUTH_HTTP_METHOD_POST, $headers);
    print_r($oauthClient->getLastResponseInfo());
}
} catch (OAuthException $e) {
print_r($e);
}
