redirect支持alter

csna.module line 92

drupal_goto($provider['authorize_uri'], array('query' => $parameters));

修改为：

$url = url($provider['authorize_uri'], array('query' => $parameters));

drupal_alter('csna_redirect', $url, $provider);

drupal_goto($url);

理由：网易的授权参数里需要token

/**
 * Implements hook_csna_redirect_alter().
 */
function csna_netease_csna_redirect_alter(&$url, $provider) {
  if ($provider['provider_id'] == 'netease') {
    module_load_include('php', 'csna_netease', 'api/tblog.class');
    
    $oauth = new OAuth($provider['key'], $provider['secret']);
    $request_token = $oauth->getRequestToken();
    
    $url = $oauth->getAuthorizeURL($request_token['oauth_token'], $provider['callback']);
  }
}
