Facebook->的getSession（）

Question

I have 2 very simple scripts:

<?php

require_once 'facebook.php';
$facebook = new Facebook(array(
'appId' => 'xxxxxxxxxxxxxxx',
'secret' => 'yyyyyyyyyyyyyyyyyyyy',
'cookie' => true,
));
?>

and

<?php
require_once 'config.php';
/* Get a valid session */
$session = $facebook->getSession();
$me = null;
if($session) {
/* Check if session is valid */
$me = $facebook->api('/me');
}
if ($me) {
echo 'User is logged in and has a valid session';
}
else {
echo 'Session expired or user has not logged in yet. 
Redirecting...';
echo '<script> top.location.href="'.$facebook->getLoginUrl()
  .'";</script>';
}
?>

Why do I get Fatal error: Call to undefined method Facebook::getSession() in C:\wamp\www\jt1\index.php on line 4?

Answer 1

There is no getSession() method in modern facebook PHP SDKm use getUser() instead.

And see sample at https://github.com/facebook/php-sdk/blob/master/examples/example.php
