I am using PHP but without using any lib. Maybe this one help you.

curl.php

class InstagramApi 
{

public function GetAccessToken($client_id, $redirect_uri, $client_secret, $code) {      
    $url = 'https://api.instagram.com/oauth/access_token';

    $curlPost = 'app_id='. $client_id . '&redirect_uri=' . $redirect_uri . '&app_secret=' . $client_secret . '&code='. $code . '&grant_type=authorization_code';
    $ch = curl_init();      
    curl_setopt($ch, CURLOPT_URL, $url);        
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);      
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);            
    $data = json_decode(curl_exec($ch), true);  
    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
    curl_close($ch);    

    if($http_code != '200')         
        throw new Exception('Error : Failed to receieve access token');

    return $data;

  }

index.php

include "curl.php";
include "instagram_keys.php"; // holding APP ID, SECRET KEY, REDIRECT URI

 $instagram_ob = new InstagramApi();
 $insta_data = $instagram_ob->GetAccessToken(INSTAGRAM_CLIENT_ID, INSTAGRAM_REDIRECT_URI, INSTAGRAM_CLIENT_SECRET, $_GET['code']);  
  echo  $insta_data['access_token'];
  echo  $insta_data['user_id'];

NOTE: $_GET['code'] is required and you should know how to get the code. Read here
