我正在为我的应用程序使用 FB id 功能登录，并开始从 GITHUB (facebook-php-sdk-master) 下载用于 FB 连接的 SDK。
在应用程序中，它有两个示例 1）用于 Javascript api 和 2）用于 PHP api。我想使用 PHP SDK 来忽略用户网站中的 javascript 禁用功能。
现在我输入了我的应用程序
$facebook = new Facebook(array(
'appId' => 'deliberately blank',
'secret' => '',
));
我登录到 facebook 以检查它是否工作，即使用户登录它也总是返回0。
我只是试图打印用户变量
$user = $facebook->getUser();
print_r($user);
我检查了应用程序设置，并为域、URL 和 Canvas URL 正确设置了它们。我还为它禁用了沙盒模式。
这是插件的问题，因为会话没有被捕获，或者我在这里做错了什么？
任何从事或面临类似问题的人请分享您的见解，因为我被卡住了，我试图打印会话数据，使用$_SESSION它返回一个数组
Array ( [fb_117096311791424_state] => 5faba08750cd6456hbf27580df3b371 )
但我没有得到用户信息。还有其他方法可以实现吗？任何替代 API 等？
