I have a command which I run on linux terminal like below:

curl –W “Authentication: Token r4r4xxxxx” “https://api.com/v1/results?display=true&format=image/jpeg&lang=en” –o image.jpg

And this command will authenticate me from the server and download the image named image.jpg to my local machine from where I am calling this command… But I am looking for a way to do this either in Ajax or Jquery or PHP would do… This is a web based application which will fetch a specific image from an API…. As I am trying to write a user friendly interface for users to be able to use this… I would like to know how can I replicate the same command above using any web based technology and how to pass parameters and both strings in quotes how would I pass them as I need them both.

Hi, which version of curl are you using? I don't have the -W option and I don't find it in the documentation.

Have you tried the PHP curl library? http://php.net/manual/en/book.curl.php
Also you could use Guzzle: http://docs.guzzlephp.org/en/latest/

An example with Guzzle:


require_once dirname(__DIR__) . '/vendor/autoload.php';

use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;

$config = ['connect_timeout' => 30
         , 'timeout' => 30
         , 'debug'   => TRUE
         , 'headers' => ['Authorization' => 'Token r4r4xxxxx']];

$client   = new Client();
$resource = fopen(tempnam('/tmp/', 'image_'), 'w');
$request  = new Request('GET', 'https://link/to/api/');

$client->send($request, array_merge($config, ['sink' => $resource]));

If you run this into a terminal you can see a verbose log of request and response, to disable just set debug to false or simply remove it from the config array.
