php - Unreadable content is returned when trying to show Nuxeo document

Question

There is an API which can be used to get the preview of a Nuxeo document; it is like this :

http://localhost:8080/nuxeo/site/api/v1/repo/default/id/563c04bf-897d-48e5-863e-08cebeeccb06/@blob/file:content/@preview/image

It should show an image content :

Now I called it inside file_get_contents and I get unreadable content :

<?php

$opts = [
            "http" => [
                "method" => "GET",
                "header" => array("Authorization: Basic " . base64_encode('Administrator:Administrator'),
                        "Content-type: image/jpg")
            ]
        ];
$context = stream_context_create($opts);

echo file_get_contents("http://localhost:8080/nuxeo/site/api/v1/repo/default/id/563c04bf-897d-48e5-863e-08cebeeccb06/@blob/file:content/@preview/image", false, $context);

?>

I tried using gzdecode but I get data error exception although magic_quotes_runtime is not present in the ini file.

So how to fix it ?

edit :

Even if curl-ing it then I get the same result :

<?php

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "http://localhost:8080/nuxeo/site/api/v1/repo/default/id/563c04bf-897d-48e5-863e-08cebeeccb06/@blob/file:content/@preview/image");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Basic ' . base64_encode('Administrator:Administrator'),
    'Content-Type: image/jpeg'
));

curl_exec($ch);

curl_close($ch);

Answer 1

Your browser needs to know how to decipher the information it receives. In this case you must "inform" him that it is a picture. Therefore you will add:

Edit: add this line before any echo

header("content-type: image/jpeg");

If the image is not jpeg you must add a suitable header

Also remove the close tag ?>
