OAuth for REST API using PHP

Question

I'm looking for a working example of a PHP script for authentication using OAuth.

I have followed the testing instructions here (http://www.magentocommerce.com/api/rest/testing_rest_resources.html) using the REST client on Firefox.

I already have created a consumer so I have the Consumer Key and Consumer Secret. But, according to the website I also need an Access Token and an Access Token Secret. I'm not entirely sure how to get those. I've googled other examples for different APIs (e.g., Twitter), but I cannot port the knowledge over to Magento.

Any help is appreciated.

Answer 1

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);
}
