Extract facebook data from access token - facebook

Question

I'm trying to use this site https://www.oneall.com/ to add social login to a test site. After setting up the code and the login I still don't know how to extract user data from access token. Here's the link I get:
http://MYACCOUNT.api.oneall.com/socialize/redirect.html?provider_connection_token=ACCESS TOKEN HERE
I get this code by the call back page like this
if ( ! empty ($_POST['connection_token']))
{
echo "Connection token received: ".$_POST['connection_token'];
}
else
{
echo "No connection token received";
}
if ( ! empty ($_POST['connection_token']))
{
$token = $_POST['connection_token'];
$site_subdomain = 'myaccountname';
$site_public_key = 'public key';
$site_private_key = 'private key';
$site_domain = $site_subdomain.'.api.oneall.com';
$resource_uri = 'https://'.$site_domain.'/connections/'.$token .'.json';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $resource_uri);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_USERPWD, $site_public_key . ":" . $site_private_key);
curl_setopt($curl, CURLOPT_TIMEOUT, 15);
curl_setopt($curl, CURLOPT_VERBOSE, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($curl, CURLOPT_FAILONERROR, 0);
$result_json = curl_exec($curl);
if ($result_json === false)
{
echo 'Curl error: ' . curl_error($curl). '<br />';
echo 'Curl info: ' . curl_getinfo($curl). '<br />';
curl_close($curl);
}
else
{
curl_close($curl);
$json = json_decode ($result_json);
$data = $json->response->result->data;
if ($data->plugin->key == 'social_login')
{
if ($data->plugin->data->status == 'success')
{
$user_token = $data->user->user_token;
$user_id = GetUserIdForUserToken($user_token);
if ($user_id === null)
{
LinkUserTokenToUserId ($user_token, $user_id);
}
else
{
}
}
}
}
}
I need to learn how to extract data now and a little example about extracting the user name by this code.

Answer 1

You can use the access token to get the connection details from oneall using their api
You use the connection_token to get the connection details (including
the user's Facebook profile data).
example
http://MYACCOUNT.api.oneall.com/connections/ACCESS TOKEN HERE.json -->>for json formatted data

Answer 2

Once you get the user's token, you then need to make a API call to Facebook, e.g. https://graph.facebook.com/me/?access_token={$access_token}
If the $access_token is correct, Facebook should return the user's details, including name, username and any other details you've asked for.
