cUrl a domain without http://www

问题

Hi i have a domain i'd like to parse with cUrl and here is the case:

When i go on domain http://register.metsad.ee/avalik/info_teatis.php?too_id=2942704201

it redirects me to [ register.metsad.ee/avalik/info_teatis.php?too_id=2942704201 ]

its the same thing without http:// www. code i use to parse is:

function get_data($url) {
        $ch = curl_init();
        $timeout = 5;
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
        $data = curl_exec($ch);
        curl_close($ch);
        return $data;
    }
$src = 'http://register.metsad.ee/avalik/info_teatis.php?too_id=2942704201';

And then $c = get_data($src); echo $c; For resoult i get a blank white page. I also tried with Simple_Html_Dom parser like this:

echo file_get_html($src)->plaintext;

But still i get a blank white page. When i trie to parse without http:// then there is an error that

Warning: file_get_contents(register.metsad.ee/avalik/info_teatis.php?too_id=2942704201) [function.file-get-contents]: failed to open stream: Result too large in C:\xampp\htdocs\Trash\metsakontroll\system\c_simple_html_dom.php on line 70

cUrl gives still white screen, no effect. When i tried to parse it like a folder like this:

http://www.metsad.ee/register/avalik/info_teatis.php?too_id=2942704201 then server says Not Found

i searched the whole internet =/ any ideas how to read that page via cUrl or Simple_html_dom ?

There is some kind of protection on register.metsad.ee side. Thay return empty response until User-Agent header is set.

Failed call (empty response):

feedbee@server:~$ telnet register.metsad.ee 80

So you need to add the next line to:

curl_setopt($ch, So you need to add CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0"); for example (or any other user agent string).
