如何为我自己的网站连接到 Magento REST API

Question

我有一个新的 Magento 站点，我无法直接控制服务器，但拥有该站点的管理员访问权限。如果有人可以解释我做错了什么和/或连接到我自己的网站的最简单方法，我将非常感激。

我已按照 http://devdocs.magento.com/guides/m1x/api/rest/authentication/oauth_authentication.html#OAuthAuthentication-PHPExamples

配置了所有 Web 服务设置

我有消费者密钥和消费者秘密。为了方便起见，我粘贴了 Magento 提供的示例 PHP 登录代码。我完全按照提供的方式使用它，而不是在我的域和凭据中进行替换。

<?php
/**
 * Example of retrieving the products list using Admin account via Magento REST API. OAuth authorization is used
 * Preconditions:
 * 1. Install php oauth extension
 * 2. If you were authorized as a Customer before this step, clear browser cookies for 'yourhost'
 * 3. Create at least one product in Magento
 * 4. Configure resource permissions for Admin REST user for retrieving all product data for Admin
 * 5. Create a Consumer
 */
// $callbackUrl is a path to your file with OAuth authentication example for the Admin user
$callbackUrl = "http://yourhost/oauth_admin.php";
$temporaryCredentialsRequestUrl = "http://yourhost/oauth/initiate?oauth_callback=" . urlencode($callbackUrl);
$adminAuthorizationUrl = 'http://yourhost/admin/oAuth_authorize';
$accessTokenRequestUrl = 'http://yourhost/oauth/token';
$apiUrl = 'http://yourhost/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";
        $oauthClient->fetch($resourceUrl, array(), 'GET', array('Content-Type' => 'application/json'));
        $productsList = json_decode($oauthClient->getLastResponse());
        print_r($productsList);
    }
} catch (OAuthException $e) {
    print_r($e->getMessage());
    echo "&lt;br/&gt;";
    print_r($e->lastResponse);
} 

我收到的错误是

making the request failed (Couldn't resolve host name)<br/>gt;

这条线失败了：

$requestToken = $oauthClient->getRequestToken($temporaryCredentialsRequestUrl);

显然是因为我定义的 $callbackUrl 无效。嗯，这里应该有什么？可以是任意网址吗？它必须与站点位于同一服务器上吗？
