更新
当将 HTTP_ 添加到值中时，原始函数将起作用。
if (isset($_GET['HTTP_SEC_GPC'])) { echo 'GPC signal detected in GET data'; } elseif (isset($_POST['HTTP_SEC_GPC'])) { echo 'GPC signal detected in POST data'; } elseif (isset($_COOKIE['HTTP_SEC_GPC'])) { echo 'GPC signal detected in COOKIE data'; } elseif (isset($_SERVER['HTTP_SEC_GPC'])) { echo 'GPC signal detected in SERVER data'; } else { echo 'No GPC signal detected'; }
感谢您建议 getallheaders()。在你的帮助下，我找到了两种方法，使用和不使用 Javascript。
