我使用的是用于PHP的facebookapi。我只能得到基本的信息，如用户名，全名，链接，id。我无法获取国家/地区、电子邮件、地点。。etc

这是我的代码，当我像国家、电子邮件、地方一样打印时，它什么都不显示！当我打印$response时它显示以下

您没有要求任何额外的权限，当然，在未获得所需权限授权的情况下，您不会收到电子邮件或其他详细信息。
查看此页面，了解如何在授权过程中请求其他权限：https://developers.facebook.com/docs/reference/php/facebook-getLoginUrl
例如，如果你想获得用户的电子邮件，你必须添加"电子邮件"权限。对于用户位置，您需要询问"user_location"。
如果需要示例（如何请求权限）：
$helper = new FacebookRedirectLoginHelper('http://example.com/callback');
$params = array('email','public_profile', 'user_status', 'user_friends');
$loginUrl = $helper->getLoginUrl($params);
我认为你需要像这样更改API请求，然后你肯定会得到facebook电子邮件id。
$request = new FacebookRequest( $session, 'GET', '/me?fields=email' );
如果你想获得更多的用户信息，你可以这样做：
$request = new FacebookRequest( $session, 'GET', '/me?fields=email,first_name,last_name,gender'.......etc );
