PHP - Retrieve Facebook image in Google Compute Engine

I've tried to retrieve the image data of my Facebook profile picture, using both file_get_contents and curl.

The problem occurs on my Google compute engine instance, while on any other server (localhost - mamp, AWS) the script works fine.

An example for one of the scripts I was using

<?php var_dump( json_decode( file_get_contents("https://graph.facebook.com/_FACEBOOK_ID_/picture?width=720&height=720") ) );

Please keep in mind that I've tried using the parameter redirect=false, and accessing the image url I've got in my json response returned false as-well.

Also, I've tried using wget in SSH to the image's url, which returned (403) Forbidden.

My assumption is that I need to configure something differently in my server, not PHP, but because I'm able to retrieve any other image, with the same script - I'm not sure what.

Answer1:

I've already experienced this exact problem, Ignoring SSL verification while using cURL did the trick for me.

$ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Ignore SSL verification curl_setopt($ch, CURLOPT_URL, "https://graph.facebook.com/_FACEBOOK_ID_/picture?width=720&height=720"); $data = curl_exec($ch); curl_close($ch); var_dump($data);
