我正在创建一个网站，使用他们的 Facebook 帐户登录的用户将在我的网站上访问他们的相册和图片。我必须在我的网站中输入什么代码才能做到这一点。我能够获得所有登录用户的所有一般信息，但不能获得他们的信息和图片。只有当我使用我的 Facebook id 登录时，所有代码才能正常工作，然后它也会提供我所有的信息图片和相册。我希望这个东西适用于所有用户。我已经阅读了很多来自 Facebook 和堆栈溢出的文档，但我找不到答案，这是我的演示链接
这是我的代码：
require '../php-sdk/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'xxxxxxxxxxx',
'secret' => 'xxxxxxxxxxxxxxxxxxxxxx',
));
// Get User ID
$user = $facebook->getUser();
$user_id = $user;
$access_token = $facebook->getAccessToken();
$SESSION['token']="CAAHk9LIIji4BAMLZCNFVMDSNEZCZCc5zfb80c8Nq4wrLZBqY56o3ZARrO3FZC9qPWXHdYpH5jZBaaADWsZBKZAdViKA5eQlKcFK579SOlOq2CXms8ZAqGZAJdXsUZAH2ZCtqPZASn3A8ZB7VXFxb4WFjPJTPUNDQlZBZCtqHcJNZA3TRozriLDCjjRdsPp5Bad9Mu1J9CdGJQZD";
$SESSION['token']= $access_token;
echo $url = "https://graph.facebook.com/me/photos?access_token=" . $SESSION['token'];
$photos = json_decode(file_get_contents($url));
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/'.$user_id);
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
// Login or logout url will be needed depending on current user state.
if ($user) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$statusUrl = $facebook->getLoginStatusUrl();
$loginUrl = $facebook->getLoginUrl();
}
?>
<?php if ($user): ?>
