I'm working on a module to integrate with the Piryx API, and per the OAuth documentation, I should be redirected to an external page where the user can allow access to my application. The problem is that I'm using drupal_http_request():

$response = drupal_http_request($url, $headers, 'GET', $data);

to get the data, and the page markup is returned in $response['data'] instead of redirecting me to the external page (if I put the URL in my browser, it brings up the page fine). Is there something I can do to redirect to the external URL so the user can allow access, or do I just somehow need to use the markup to display it in my site?

Thanks.

In the case the request is redirect to a different URL, $response->code is 301, and $response->redirect_url is the redirection URL. If the request is redirect, you can call drupal_http_request() using $response->redirect_url as new URL.

See aggregator_aggregator_fetch() as example of Drupal function that verifies the request is being redirected.

  // Process HTTP response code.
  switch ($result->code) {
    case 304:
      break;
    case 301:
      $feed->url = $result->redirect_url;
      // Do not break here.
    case 200:
    case 302:
    case 307:
      if (!isset($result->data)) {
        $result->data = '';
      }
      if (!isset($result->headers)) {
        $result->headers = array();
      }
      $feed->source_string = $result->data;
      $feed->http_headers = $result->headers;
      break;
    default:
      watchdog('aggregator', 'The feed from %site seems to be broken, due to "%error".', array('%site' => $feed->title, '%error' => $result->code . ' ' . $result->error), WATCHDOG_WARNING);
      drupal_set_message(t('The feed from %site seems to be broken, because of error "%error".', array('%site' => $feed->title, '%error' => $result->code . ' ' . $result->error)));
  }

If you want to redirect the users to $result->redirect_url, and not requesting that URL with drupal_http_request(), you use the following code.

drupal_goto($response->redirect_url, array('absolute' => TRUE));
  • OK, I'm confused. The response code I'm getting is actually 302. What I can't figure out is how to actually redirect the user to the location in $response->redirect_url, because I need the user the allow access to my application on that page. Calling drupal_http_requeset() again doesn't do that; it just gives me another response object. – wonder95 Oct 13 '11 at 13:45
  • If you look at aggregator_aggregator_fetch(), you will see that the code 302 is handled as if the drupal_http_request() returned 200. – kiamlaluno Jul 13 '12 at 1:52
