Facebook php sdk：请求链接许可，而不是重定向
我想更改我的代码，首先它会检查用户是否喜欢该页面。此后（如果是）将会出现一个问题，要求接受条款，如果他点击接受按钮，Facebook 权限请求对话框将会出现。我该怎么做？
问题是，每次用户单击应用程序链接时，$user 变量始终为 false，但他已登录......
<?php
require 'facebook.php';
$facebook = new Facebook(array(
'appId' => 'xxxxx',
'secret' => 'yyyyy',
'baseUrl' => 'http://hosting.address/',
'appBaseUrl' => 'http://apps.facebook.com/app-name/',
'fileUpload' => 'true',
));
// Get User ID
$user = $facebook->getUser();
$params = array(
scope => 'publish_stream,user_photos',
redirect_uri => 'http://www.facebook.com/xxxxx?sk=app_yyyyy&app_data=1'
);
$signed_request = $facebook->getSignedRequest();
$app_data = $signed_request["app_data"];
?>
<!doctype html>
<html xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<title>the title</title>
</head>
<body>
<?php if ($user){
try {
$user_profile = $facebook->api('/me');
$likes = $facebook->api("/me/likes/123123123"); //page ID
if( !empty($likes['data']) ){
$scope = 'publish_stream,user_photos';
$scope_params = explode(',',$scope);
$permissions = $facebook->api("/me/permissions");
if( array_key_exists('publish_stream', $permissions['data'][0]) && array_key_exists('user_photos', $permissions['data'][0]) && isset($app_data)) {
} else {
echo "<a href=\"/redirect.php\">accept</a></td>";
echo "<a href=\"http://www.facebook.com/pageurl\">deny</a></td>";
}
}else{
echo "<img width=\"520px\" src=\"no-fan.jpg\" />";
}
} catch (FacebookApiException $e) {
echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
$user = null;
}
}
if ($user) {
} else {
$loginUrl = $facebook->getLoginUrl($params);
echo '<script type="text/javascript">top.location.href = "'.$loginUrl .'";</script>';
}
?>
</body>
</html>
I want to change my code so, that first it will check if the user has liked the page. After this (if yes) a question will come up, to accept the terms and if he clicks on the accept button the Facebook permissions request dialog will come up. How can i do this?
The problem is that everytime a user clicks on the app link the $user variable is always false, but he is logged in...

require 'facebook.php';
$facebook = new Facebook(array(

'fileUpload' => 'true',
));
// Get User ID
$user = $facebook->getUser();
$params = array(
scope => 'publish_stream,user_photos',
redirect_uri => 'http://www.facebook.com/xxxxx?sk=app_yyyyy&app_data=1'
);
$signed_request = $facebook->getSignedRequest();
$app_data = $signed_request["app_data"];

尝试遵循这个优秀的示例：

然后在 fanpage.php 上添加代码来要求他们登录。
