PHP:CURL 可以跟随元重定向吗 [英] PHP: Can CURL follow meta redirects

问题描述

CURL 可以使用 CURLOPT_FOLLOWLOCATION 跟随标头重定向，但是否可以跟随元刷新重定向?

CURL can follow header redirects with the use of CURLOPT_FOLLOWLOCATION but is it possible to follow meta refresh redirects?

谢谢

推荐答案

是的，但您必须自己通过解析响应并查找类似以下内容的方式来完成:

Yes, but you'll have to do it yourself by parsing the response and looking for things that look like:

<meta http-equiv="refresh" content="5;url=http://example.com/" />

遵守 刷新请求是浏览器端的事情.使用 DOM 解析在 cURL 为您提供的响应中查找具有适当属性的 标记.

Obeying <meta> refresh requests is a browser-side thing. Use DOM parsing to look for <meta> tags with the appropriate attributes in the response cURL gives you.

如果你能保证响应是有效的 XML，你可以这样做:

If you can guarantee that the response is valid XML, you could do something like this:

$xml = simplexml_load_file($cURLResponse);
$result = $xml->xpath("//meta[@http-equiv='refresh']");
// Process the $result element to get the relevant bit out of the content attribute
