无法确定请求文件的原因

Question

您好，我正在网站上工作并使用 chrome 中的开发人员工具，我看到请求文件 undefined?1428992352055 请求我的服务器 returns 一个 404。我无法确定请求此文件的原因或位置。 它也不会在您每次加载页面时发生，通常是在重新加载时发生。下面是 headers，我认为这是所有需要的，但我已经搜索了又搜索，无法弄清楚这个文件发生了什么。任何建议表示赞赏。

没有进行缓存，我在整个服务器中搜索了这个字符串，希望删除对它的引用。我已经在互联网上搜索了这个问题，但无法找出是什么原因造成的。

在阅读我的 post 以确保没有太多错误时，这句话让我印象深刻。 X-Pingback:http://example.com/xmlrpc.php 所以我去了服务器，这是该文件中可能是罪魁祸首的内容。

我尝试重新加载它几次，但没有收到任何错误。如果您认为 xml-rpc 是罪魁祸首，那么只需将其从 header 中删除即可。如果您不使用任何远程发布功能，那么删除它总是好的，因为它会导致安全问题。要删除它，只需将其包含在您的函数文件中

function remove_x_pingback($headers) {
    unset($headers['X-Pingback']);
    return $headers;
}
add_filter('wp_headers', 'remove_x_pingback');
