未找到卷曲元素错误

Question

I am stuck in a situation when I get content of a web page through CURL then I received page content but got error query result not present there. I always got element not found error.

But when I put URL in browser then got appropriate result. How can I resolve that?

URL I am using is http://164.100.9.38/judis/handle/123456789/30346/simple-search?query=%28%28petitioner:ajay%29%29&from_advanced=true&query11=&query9=&query8=&conjunction8=AND&conjunction9=AND&query10=&conjunction6=AND&conjunction7=AND&field5=judge&field4=petitioner&field3=respondent&field2=caseyear&field9=abstract&field8=type&field7=datejudgement&conjunction10=AND&field6=headnotes&query4=ajay&query5=&query6=&query7=&field1=casenumber&query1=&query2=&query3=&conjunction3=AND&conjunction2=AND&conjunction5=AND&conjunction4=AND&field10=citation&conjunction1=AND&field11=keyword&num_search_field=11

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

Thanks in advance.

You need to login on the site first or create a session first. They are using session. Surprisingly they are providing session id on page http://164.100.9.38/judis/styles.css.jsp.

So request http://164.100.9.38/judis/styles.css.jsp first. It'll set the cookie. And then request your usual way.

To keep your session cookies use CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR options.

curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
