Answer 1

发生此错误是因为您无权在网页上发帖。左页需要发布权限 publish_actions 。
您的登录URL如下所示：
$loginUrl = $helper->getLoginUrl(array('publish_actions')); / *登录网址有权限* /
为了检查用户执行的授权这样的事情：
$user_permissions = (new FacebookRequest($session, 'GET', '/me/permissions'))->execute()->getGraphObject(GraphUser::className())->asArray();
var_dump($user_permissions);
