Title Body

I'm trying to follow the example to create a server side login to Facebook from here , but with no luck. In step 7, when I try to exchange the code with a token and store it in a session for later use, I always get this error : file_get_contents(): failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request I know this already asked many times, but I still unable to solve this, as per this question , I tried using cURL, but it still does not work, it just returned false. Other question told me to use the PHP SDK, but I don't know which method to use. So I'm completely lost in here. Here's my code for calling the login form : <a href="<?php echo LOGIN_URL; ?> ?>" class="btn btn-primary">Login with Facebook</a> where LOGIN_URL is defined as : define("LOGIN_URL", $facebook->getLoginUrl(array("redirect_uri" => APP_URL . "fb_login"))); in fb_login, I have this code : $app->get("/fb_login", function() use($app, $facebook) { $code = $_REQUEST["code"]; $token_url = "https://graph.facebook.com/oauth/access_token?" . "client_id=" . APP_ID . "&redirect_uri=" . APP_URL . $_SESSION["request_uri"] // Previous URL . "&client_secret=" . APP_SECRET . "&code=" . $code; $response = file_get_contents($token_url); // Doesn't work $params = null; parse_str($response, $params); $_SESSION["access_token"] = $params["access_token"]; // Let's try with cURL... // $ch = curl_init(); //
