Here's my Image.php file:
<?php
class Image {
public static function uploadImage($formname, $query, $params) {
$image = base64_encode(file_get_contents($_FILES[$formname]['tmp_name']));
$options = array('http'=>array(
'method'=>"POST",
'header'=>"Authorization: Bearer ###\n".
"Content-Type: application/x-www-form-urlencoded",
'content'=>$image
));
$context = stream_context_create($options);
$imgurURL = "https://api.imgur.com/3/image";
if ($_FILES[$formname]['size'] > 10240000) {
die('Image too big, must be 10MB or less!');
}
$response = file_get_contents($imgurURL, false, $context);
$response = json_decode($response);
$preparams = array($formname=>$response->data->link);
$params = $preparams + $params;
DB::query($query, $params);
}
}
?>

Answer 1

You making bad request.
At the beginning you need to generate your Client ID (more info # https://api.imgur.com/#registerapp)
To do this go to https://api.imgur.com/oauth2/addclient
and
Select Anonymous usage without user authorization option as Authorization Type.
Use Authorization: Client-ID not Bearer, you can keep file_get_contents (so - then you need change only authorization header) but CURL will be better for this.
Example with CURL:
<?php
class Image
{
public static function uploadImage($formname, $query, $params)
{
$client_id = 'YOUR CLIENT ID';
$image = base64_encode(file_get_contents($_FILES[$formname]['tmp_name']));
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => 'https://api.imgur.com/3/image.json',
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTPHEADER => array(
'Authorization: Client-ID ' . $client_id
) ,
CURLOPT_POST => TRUE,
CURLOPT_RETURNTRANSFER => TRUE,
CURLOPT_POSTFIELDS => array(
'image' => $image
)
));
$out = curl_exec($curl);
curl_close($curl);
$response = json_decode($out);
$preparams = array(
$formname => $response->data->link
);
$params = $preparams + $params;
DB::query($query, $params);
}
}

Answer 2

file_get_contents() is used for GET requests. You need to use CURL in PHP in order to make a POST request from a server to another.
