Checking mobile token by Game Server after authorization

This is a sample code that implements last step of authorization process - checking mobile token by Game Server.

You need send access_token from your mobile application to Game Server and check it in our Authorization server. If checking is successful you'll receive in response user account data.

PHP

$access_token = $_POST['access_token'];    // From mobile client
$request = [
    'http' => [
        'header'  => 'Authorization: Bearer ' . $access_token,    // You must use access_token in header
        'method'  => 'GET',
    ],
];
$context  = stream_context_create($request);
$response = file_get_contents('https://auth.101xp.com/tokens/mobile', false, $context);
if ($response === false) {
    $result = [
        'status'        => 'error',
        'error_message' => 'Wrong API response.',
    ];
} else {
    $response = json_decode($response, true);
    if($response['status'] == 'success'){
        $account_id  = $response['mobile']['id'];    // You need to use it to create ingame user account
        if(!empty($response['portal'])){
            // You can use Portal account data to personalize game account
            $user_id     = $response['portal']['id'];
            $user_name   = $response['portal']['display_name'];
            $user_avatar = $response['portal']['photo'];
        }
 
        // Your other code here
 
        $result = [
            'status' => 'success',
            'data'   => [
                'data',
                'for',
                'game',
                'client',
            ],
        ];
    } else {
        $result = [
            'status'        => 'error',
            'error_message' => 'Response contain errors.',
        ];
    }
}
echo json_encode($result);
