esc_url 在样式表URL上运行converts those characters. 你可以用几个过滤器来解决这个问题。

function style_params($src, $handle) {
  if (\'twentyfourteen-style\' == $handle) {
    add_filter(\'clean_url\',\'alter_clean_url\',10,3);
  }
  return $src;
}
add_filter(\'style_loader_src\',\'style_params\',10,2);

function alter_clean_url($good_protocol_url, $original_url, $_context ) {
  remove_filter(\'clean_url\',\'alter_clean_url\',10,3);
  $good_protocol_url = html_entity_decode($good_protocol_url);
  $good_protocol_url = $good_protocol_url.\'&abc=def\';
  return $good_protocol_url;
}
