How to turn API response into an image? - php

Question

I'm trying to work with an API using Postman. In Postman the image displays fine. I am using Postman to generate the following code
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.com/v2/tier1/XXXXX/photos/photo/MYPHOTOIDISHERE/download?api_key=MYAPIKEYISHERE",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"cache-control: no-cache",
"postman-token: 74f19da6-d4ba-fe02-4ad3-2a313b472ca2"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
The only modification I have made to the code from Postman is the CURLOPT_SSL_VERIFYPEER as I was getting an error.
The image displays perfectly in Postman but when I try to use the code myself I get a long string that looks like UTF. A small sample (it's very long) of this is as follows;
����JFIF``��C #!!!$'$ & ! ��C ����"�� ���}!1AQa"q2���#B��R��$3br� %&'()*456789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz��������������������������������������������������������������������������� ���w!1AQaq"2�B���� #3R�br� $4�
How do I convert this into an image?

Answer 1

The result you are seeing is the actual bytes of the image.
You need to save that to a file or process it as image bytes. To save it, dump it to a file using file_put_contents($filename, $data)
// Instead of 'echo $response';
file_put_contents('image.jpg', $response);
You will see a new file image.jpg in your script's directory.
This assumes the image is a jpeg, you could do some checks to determine the type before saving it.

Answer 2

I am able to save image in folder, but problem is that Its showing error - window photo viewer can't open this picture because the file appears to be damaged, corrupted or is too large
here is my code
$oAuthToken = $token->access_token;
$getUrl = 'https://www.googleapis.com/drive/v2/files/' . $googlefileid . '?alt=media';
$authHeader = 'Authorization: Bearer ' . $oAuthToken ;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $getUrl);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
$authHeader ,
]);
$data = curl_exec($ch);
curl_close($ch);
Storage::put($googlfilename,$data);
Please tell me what i am doing wrong.
