Question

我想获取重定向网址中的最终网址。我有这个功能：

    function get_redirect_final_host_url($url){
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // follow redirects
    curl_setopt($ch, CURLOPT_AUTOREFERER, 1); // set referer on redirect
    curl_exec($ch);
    $target = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
    curl_close($ch);
$website_host_url = str_ireplace('www.', '', parse_url($target)['host']);
return $website_host_url;
}

但是它不适用于所有链接，有些链接是：

https://www.goldpoll.com/out.php?p=28017
https://investlister.com/go/lid/68/

Answer 1

<?php
$target = 'https://investlister.com/go/lid/68/';
$website_host_url = str_ireplace('www.', '', parse_url($target)['host']);

echo $website_host_url; // investlister.com

这完全符合您的预期

好时间；您需要访问带有https的curl函数测试一下：

function get_redirect_final_host_url($url){
    $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_NOBODY, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // follow redirects
        curl_setopt($ch, CURLOPT_AUTOREFERER, 1); // set referer on redirect
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // get access ssl
        curl_exec($ch);
        $target = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
    curl_close($ch);
    $website_host_url = str_ireplace('www.', '', parse_url($target)['host']);
    return $website_host_url;
}

重定向中的最终网址
