Drupal自身的url rewrite

应该只对url函数输出有效。

例子（写在settings.php里）：

function custom_url_rewrite_outbound(&$path, &$options, $original_path) {
  global $user;

  // Change all 'node' to 'article'.
  if (preg_match('|^node(/.*)|', $path, $matches)) {
    $path = 'article' . $matches[1];
  }
  // Create a path called 'e' which lands the user on her profile edit page.
  if ($path == 'user/' . $user->uid . '/edit') {
    $path = 'e';
  }

  if (preg_match('|/imagecache/|', $path, $matches)) {
        $options['base_url'] = 'http://www.mirror.com';
        $options['absolute'] = true;
  }

}

function custom_url_rewrite_inbound(&$result, $path, $path_language) {
  global $user;

  // Change all article/x requests to node/x
  if (preg_match('|^article(/.*)|', $path, $matches)) {
    $result = 'node' . $matches[1];
  }
  // Redirect a path called 'e' to the user's profile edit page.
  if ($path == 'e') {
    $result = 'user/' . $user->uid . '/edit';
  }
}
