使用Curl PHP获取最终重定向

问题描述

我必须从这里获取最终的重定向网址：，其实际上会重定向到此：

I have to get the final redirect url from the this: https://web.archive.org/web/20070701005218/http://www.maladnews.com/ which actually redirects to this: https://web.archive.org/web/20080109064420/http://www.maladnews.com/Site%203/Malad%20City%20&%20Oneida%20County%20News/Malad%20City%20&%20Oneida%20County%20News.html

我试过其他stackoverflow答案的答案，适用于其他网站，但不是上述链接。

I tried the answers from other stackoverflow answers which works for other websites but not for the above link.

我试图提取常规位置标题：

I've tried to extract regular location header:

if(preg_match('#Location: (.*)#', $html, $m))
 $l = trim($m[1]);

并检查javascript方式：

and also checked the javascript way:

preg_match("/window\.location\.replace\('(.*?)'\)/", $html, $m) ? $m[1] : null;

请帮助！

推荐答案

使用 curl_getinfo（） CURLINFO_REDIRECT_URL 或 CURLINFO_EFFECTIVE_URL b
$ b

Use curl_getinfo() with CURLINFO_REDIRECT_URL or CURLINFO_EFFECTIVE_URL depending on your use case.

- http://php.net/manual/en/function.curl-getinfo.php a>

<?php
$url = 'https://google.com/';

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);

$html = curl_exec($ch);

$redirectedUrl = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);

curl_close($ch);

echo "Original URL:   " . $url . "\n";
echo "Redirected URL: " . $redirectedUrl . "\n";

当我运行此代码时，输​​出是：

When I run this code, the output is:

Original URL:   https://google.com/
Redirected URL: https://www.google.com/
