Running the Magento REST API php example

Question

I'm trying to run the Magento REST API example for fetching item information. This is the code I have:

<?php
/**
 * Example of products list retrieve using Customer account via Magento REST API. OAuth authorization is used
 */
$callbackUrl = "http://localhost/oauth_admin.php";
$temporaryCredentialsRequestUrl = "http://localhost/oauth/initiate?oauth_callback=" . urlencode($callbackUrl);
$adminAuthorizationUrl = 'http://localhost/admin/oauth_authorize';
$accessTokenRequestUrl = 'http://localhost/oauth/token';
$apiUrl = 'http://localhost/magento/api/rest';
$consumerKey = 'mykey';
$consumerSecret = 'mysecret';

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";
        $oauthClient->fetch($resourceUrl);
        $productsList = json_decode($oauthClient->getLastResponse());
        print_r($productsList);
    }
} catch (OAuthException $e) {
    print_r($e);
}

Now, when I try to run this example using php <filename>.php, I get the following error:

PHP Notice:  Undefined index: state in /Desktop/magento.php on line 18
PHP Notice:  Undefined index: state in /Desktop/magento.php on line 22

I do not get any other output / errors. What is the problem here? When I try to access Magento using Java / Scribe, I'm able to get the access token. I'm having Magento CE 1.9.

Thanks.

It looks like this code sample was not meant to be run with php <filename>.php in command line, but in Web server context (for example, the use of $_GET means this script expects to get some query parameters).

If you don't have a Web server up and configured to place this script on, and assuming your PHP version is 5.4 or newer, you can run this using the built-in server, like so:

php -S localhost:8080 <filename>.php

Then access http://localhost:8080 with your browser and see if it works.

Note that the built-in Web server is useful for testing and development, but is not suited for production use.
