在这个简单的 php 文件中:( http://gist.github.com/273402 )
<?php
session_start();
include_once 'libraries/facebook/facebook.php';
//$fb_user=$facebook->get_loggedin_user();
?>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script>
<script type="text/javascript">
FB.init("PUBLIC_KEY", "http://localhost/xd_receiver.htm",{"reloadIfSessionStateChanged":true});
</script>
</head>
<body>
<h1>User index</h1>
<fb:login-button onlogin="window.location.reload(true)"></fb:login-button>
<fb:profile-pic uid="loggedinuser" size="square" facebook-logo="true"></fb:profile-pic>
<?php
$facebook = new Facebook("PUBLIC_KEY","SECRET");
if($facebook->get_loggedin_user()){
echo "logged";
} else {
echo "not-logged";
};
?>
</body>
</html>
我无法获得 $facebook->get_loggedin_user(),但 FBXML 确实渲染了个人资料图片,为什么?
我如何在 PHP 中获取用户信息,而不是在 JS 中?
