PHP：CURL可以跟随元重定向 [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，但是可以跟随元刷新重定向吗？

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

感谢

推荐答案

是的，但是你必须自己通过解析响应来寻找类似的东西：

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/" />

符合< meta> 一个浏览器端的东西。使用DOM解析在响应cURL中查找具有适当属性的< meta> 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
