PHP cURL return blank page

Question

I had been using PHP curl to get the contents of a file, hosted on a different server. The file can easily be opened on a browser like Chrome etc., but with cURL, it always returns a blank page.

The file is hosted on an Nginx server and even miniproxy.php fails to get contents. Instead, it returns 406 not acceptable. I tried using the HTTP spy extension to monitor the request sent and found the following header:

Upgrade-Insecure-Requests:1 I tried sending the same header along With other headers, but in vain. Still, I couldn't rectify my mistake. On the Internet, I found the zalmos proxy which was able to get the contents of the file. The curl code I wrote is attached below.

$url = "http://smumcdnems01.cdnsrv.jio.com/jiotv.live.cdn.jio.com/" . $ch . "/" . $ch . "_" . $q  . ".m3u8" . $tok;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
   "User-Agent: agent",
   "lbcookie: 300",
   "devicetype: 1",
   "os: android",
   "appkey: 1111111",
   "deviceId: device id",
   "uniqueId: unique id",
   "ssotoken: any token",
   "Upgrade-Insecure-Requests: 1",
   "Host: example.com",
   "Connection: keep-alive",
   "X-Chrome-offline: persist=0 reason=reload",
   "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9",
   "Accept-Encoding: gzip, deflate, sdch",
   "Accept-Language: en-GB,en-US;q=0.9,en;q=0.8",
   "subscriberId: any id",
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
//for debug only!
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$resp = curl_exec($curl);
curl_close($curl);
echo $url;
echo $resp;

I believe that any part is missing in my code which is posing a problem. How can this be rectified?

Check your URL. Curl must give you the response. If it's hit the target URL, either the target URL is not responding to anything when sending the request.

The url gives the data while browsing on chrome but doesn't give it when curl request is passed on . – PIYUSH ADLAKHA Jan 27 '21 at 13:19

You may be trying to access a websocket. Try to simulate with Postman to get more information.
