在facebook documantion中
require('include/facebook/autoload.php'); //SDK directory
$fb = new Facebook\Facebook([
'app_id' => '***********',
'app_secret' => '***********************'
]);
$helper = $fb->getRedirectLoginHelper();
$permissions = ['email', 'public_profile']; // optional
$loginUrl = $helper->getLoginUrl('http://www.meusite.com.br/login-callback.php', $permissions);
当它指向url $ loginUrl时,返回的是:Facebook SDK返回错误:跨站点请求伪造验证失败.来自URL和会话的"状态"参数不匹配
