I need to read the size of a file but the server is forcing me to download it first. I note one of the response headers is Content-Type: application/force-download and that seems to bypass my curl inputs...
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch,CURLOPT_TIMEOUT,1000);
curl_exec($ch);
$bytes = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
curl_close($ch);
Any ideas?
Curl conforms with the force-download header, but file_get_contents can be used to limit the file download download to only 1 byte. This solved the problem!
$postdata = http_build_query(
array(
'username' => "",
'password' => ""
)
);
$params = array(
'http' => array
(
'method' => 'POST',
'header'=>"Content-type: application/x-www-form-urlencoded
",
'content' => $postdata
)
);
$ctx = stream_context_create($params);
file_get_contents($url,false,$ctx,0,1);
$size = str_replace("Content-Length: ","",$http_response_header[4]);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
These two lines reset CURLOPT_NOBODY.
CURLOPT_NOBODY changes method to HEAD and CURLOPT_POST changes it to POST.
