来自本地主机的Google Analytics API

使用php脚本，使用Google php客户端API从Google Analytics中提取数据。我已经在localhost/ga/上设置了脚本。

我的API密钥都设置好了，分析API打开。

在"Web应用程序的客户端ID"中：

REDIRECT URIS  http://localhost/ga/
JAVASCRIPT ORIGINS http://localhost

在"浏览器应用程序密钥"中：

REFERERS  http://localhost/*

仔细检查了所有密钥、ID和机密。但我得到了这个错误：

"(403) There is a per-IP or per-Referer restriction configured on your API key and the request does not match these restrictions. Please use the Google Developers Console to update your API key configuration if request from this IP or referer should be allowed."

我当前的代码：

$client = new Google_Client();
$client->setApplicationName('GA Test');
$client->setClientId($cred['id']);
$client->setClientSecret($cred['secret']);
$client->setRedirectUri($cred['redirect']);
$client->setDeveloperKey($cred['api_key']);
$client->setScopes(array('https://www.googleapis.com/auth/analytics.readonly'));
if (isset($_GET['code'])) {
    $client->authenticate($_GET['code']);
    $_SESSION['token'] = $client->getAccessToken();
    $redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
    header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}
if (isset($_SESSION['token'])) {
    $client->setAccessToken($_SESSION['token']);
}
if($client->isAccessTokenExpired()) {
    $authUrl = $client->createAuthUrl();
    header('Location: ' . filter_var($authUrl, FILTER_SANITIZE_URL));
}
if (!$client->getAccessToken()) {
    $authUrl = $client->createAuthUrl();
    echo '<a class="login" href="'.$authUrl.'">Connect Me!</a>';
} else {
    $analytics = new Google_Service_Analytics($client);
    try {
        $optParams = array(
            'dimensions' => 'ga:source,ga:keyword',
            'sort' => '-ga:sessions,ga:source',
            'filters' => 'ga:medium==organic',
            'max-results' => '25'
        );
        $dump =  $analytics->data_ga->get(
            'ga:52371304',
            '2015-01-01',
            '2015-03-01',
            'ga:sessions',
            $optParams
        );
        var_dump($dump);
        echo 'hi!';
    } catch(Exception $e) {
        echo $e->getMessage();
    }
}

知道我可能做错了什么吗？
