Code

function node_page_view(Node $node) {

  // If there is a menu link to this node, the link becomes the last part
  // of the active trail, and the link name becomes the page title.
  // Thus, we must explicitly set the page title to be the node title.
  drupal_set_title($node
    ->label());
  $uri = $node
    ->uri();

  // Set the node path as the canonical URL to prevent duplicate content.
  drupal_add_html_head_link(array(
    'rel' => 'canonical',
    'href' => url($uri['path'], $uri['options']),
  ), TRUE);

  // Set the non-aliased path as a default shortlink.
  drupal_add_html_head_link(array(
    'rel' => 'shortlink',
    'href' => url($uri['path'], array_merge($uri['options'], array(
      'alias' => TRUE,
    ))),
  ), TRUE);
  return node_show($node);
