无法获取Google Client API simple.php示例

Question

Just trying to use the Google Client API to pull traffic data for my site and thought I would try the simple.php file on https://code.google.com/p/google-api-php-client/source/browse/trunk/examples/contacts/simple.php

I've edited it appropriately for my credentials and I can get it to go from the "Connect Me" link to the request permission page, but after I accept I end up at "This webpage is not available". I'm wondering if there might be an issue with needing the token refreshed?

Any thoughts are greatly appreciated. Thanks!

// Visit https://code.google.com/apis/console?api=analytics to generate your
// client id, client secret, and to register your redirect uri.

$service = new Google_AnalyticsService($client);

  $redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
  header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
