Php: Can Curl Follow Meta Redirects

PHP: Can CURL follow meta redirects

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/" />

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.

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

How follow meta redirect with curl and php?

I found an implementation in a comment of get_meta_tags() documentation page.

function sendRequest($url)
{
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

    /*curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'GET '.$url.' HTTP/1.1', // Are you sure about this?
        'User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3',
        'Accept: text/html',
        'Accept-Language: ru,en-us;',
        'Accept-Charset: windows-1251,utf-8;',
        'Connection: close'
    ));*/

    $contents = curl_exec($ch);
    curl_close($ch);

    return $contents;
}

function getUrlContents($url, $maximumRedirections = null, $currentRedirection = 0)
{
    $result = false;

    $contents = sendRequest($url);

    // Check if we need to go somewhere else

    if (isset($contents) && is_string($contents))
    {
        preg_match_all('/<[\s]*meta[\s]*http-equiv="?REFRESH"?' . '[\s]*content="?[0-9]*;[\s]*URL[\s]*=[\s]*([^>"]*)"?' . '[\s]*[\/]?[\s]*>/si', $contents, $match);

        if (isset($match) && is_array($match) && count($match) == 2 && count($match[1]) == 1)
        {
            if (!isset($maximumRedirections) || $currentRedirection < $maximumRedirections)
            {
                return getUrlContents($match[1][0], $maximumRedirections, ++$currentRedirection);
            }

            $result = false;
        }
        else
        {
            $result = $contents;
        }
    }

    return $contents;
}

echo getUrlContents('http://wtion');

follow redirects with curl in php

cURL will not follow JS or meta tag redirects.

grab redirected url by using cURL

this page does not use a redirect-scheme that libcurl understands (it uses a html <meta http-equiv="REFRESH"-redirect, unsupported by libcurl), so libcurl can neither tell you where it is being redirected, nor can libcurl auto-follow the redirect (because libcurl does not understand it)

you need to parse out the redirect url yourself from the HTML, eg

function redirect1($url) { 
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,0);
        curl_setopt($ch, CURLOPT_TIMEOUT, 60);
        $data = curl_exec($ch);
        $domd=@DOMDocument::loadHTML($data);
        $xp=new DOMXPath($domd);
        // <META http-equiv="REFRESH" content="0;URL=http://sumai.tokyu-land.co.jp/branz/roppongi4/?iad=daikyo" />

        $location=$xp->query("//meta[@http-equiv='REFRESH']")->item(0)->getAttribute("content");
        // 0;URL=http://sumai.tokyu-land.co.jp/branz/roppongi4/?iad=daikyo   
        $location=substr($location,stripos($location,'URL=')+4);
        curl_close($ch);
        return $location;
    }
    var_dump(redirect1('https://lions-mansion.jp/MA141070/'));

output:

C:\projects\misc>php re.php
string(57) "http://sumai.tokyu-land.co.jp/branz/roppongi4/?iad=daikyo"

Get cURL to follow redirects

curl has an option to achieve exactly what you are looking for,
following redirects:

curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);

Just add this line to your curl-options before your execution of it.

As you might expect, this will follow any 301 / 302 redirects and ends up on a site, which doesn't redirect your request any further.

Also, remember that (without having a workaround) this might lead to an infinite loop. (site a redirects to b and b redirects to a).

That said, you should use this option as well:

curl_setopt($curl, CURLOPT_MAXREDIRS, 10);

This way, your requests will end after 10 redirects and you don't have to bother with your script running in an endless-loop.

A good source for your further work with diffrent options is the regarding site on php.net

PHP get response for POST after redirect

I managed to get it to return the redirect URL by following this thread:

Curl, follow location but only get header of the new location?

I added the following to my script:

$redirect = curl_getinfo($ch)['redirect_url'];
echo $redirect;
