PHP post to api, receive an image

Question

Trying to post to a url, and recieve an image.
for example (this works in the browser):

https://providers.cloudsoftphone.com/lib/prettyqr/createQR.php?user=123&pass=321&cloudid=test&format=png

my code:

$url = 'https://providers.cloudsoftphone.com/lib/prettyqr/createQR.php';
$fields = array(
  'user'=> 123,
  'pass'=> 321,
  'cloudid'=> 'test',
  'format'=> 'png'
);

$options = array(
    'http' => array(
    'header'  => 'Content-type: application/x-www-form-urlencoded',
    'method'  => 'POST',
    'content' => http_build_query($fields)
    )
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);

tried following this answer.

returns "invalid input"

**EDIT**

also trying with curl:

$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec( $ch );
var_dump($response);

same result ('invalid input')

The link you indicated is a GET, not a POST. Try changing your method to GET and see what happens. — Aleks G

Does the API require you to use HTTP GET or POST for the request? The link example would be using GET but the PHP code is using POST — AeroX

Trying at hurl.it, it works for me, using both GET and POST — leo

Does it work when you put ?cloudid=test in the url (instead of sending it through $options['content'])= — leo

Check this

You should add parameters to query instead of context which is not necessary at all

$url = 'https://providers.cloudsoftphone.com/lib/prettyqr/createQR.php';
$fields = array(
  'user'=> 123,
  'pass'=> 321,
  'cloudid'=> 'test',
  'format'=> 'png'
);

$result = file_get_contents($url."?".http_build_query($fields));
var_dump($result);

Thanks, maybe you can explain the logic of not having to provide header/method etc .. ?

You posted link which is working. Links are GET request. GET is default method, so there is no need to specify it. In GET request you can't have content, so there is no reason to specify it's type either.

You can use JQuery to send a post request and then take the respons via Jquery

Add jquery library to the html file
Create a simple html form with a button
And try bellow code

<input type="button" name="bttnLoadQR" onClick="
$.post( "https://providers.cloudsoftphone.com/lib/prettyqr/createQR.php", 
{ user: "123", pass: "321", cloudid: "test", format: "png" },
function(data){
  $('#result').html(data);
});
">
<div id="result"></div>

Check here http://jsfiddle.net/S8Lgp/212/
