必须使用活动访问令牌来查询有关当前用户的信息
<?php
define('YOUR_APP_ID', 'x');
define('YOUR_APP_SECRET', 'x');
function get_facebook_cookie($app_id, $app_secret) {
$args = array();
parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
ksort($args);
$payload = '';
foreach ($args as $key => $value) {
if ($key != 'sig') {
$payload .= $key . '=' . $value;
}
}
if (md5($payload . $app_secret) != $args['sig']) {
return null;
}
return $args;
}
$cookie = get_facebook_cookie(YOUR_APP_ID, YOUR_APP_SECRET);
$url = 'https://graph.facebook.com/me?access_token=' . $access_token;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
curl_close($ch);
$user = json_decode($response);
print_r($user);
?>
<html>
<body>
<?php if ($cookie) { ?>
Welcome <?php ?>
<?php } else { ?>
<fb:login-button></fb:login-button>
<?php } ?>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({appId: '<?= YOUR_APP_ID ?>', status: true,
cookie: true, xfbml: true});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
</script>
</body>
</html>
有谁知道为什么我会得到这个例外？ $user 的 print_r 正在产生
stdClass Object ( [error] => stdClass Object ( [type] => OAuthException [message] => An active access token must be used to query information about the current user. ) )
为什么会发生这种情况？
<?php
define('YOUR_APP_ID', 'x');
define('YOUR_APP_SECRET', 'x');
function get_facebook_cookie($app_id, $app_secret) {
$args = array();
parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
ksort($args);
$payload = '';
foreach ($args as $key => $value) {
if ($key != 'sig') {
$payload .= $key . '=' . $value;
}
}
if (md5($payload . $app_secret) != $args['sig']) {
return null;
}
return $args;
}
$cookie = get_facebook_cookie(YOUR_APP_ID, YOUR_APP_SECRET);
$url = 'https://graph.facebook.com/me?access_token=' . $access_token;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
curl_close($ch);
$user = json_decode($response);
print_r($user);
?>
<html>
<body>
<?php if ($cookie) { ?>
Welcome <?php ?>
<?php } else { ?>
<fb:login-button></fb:login-button>
<?php } ?>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({appId: '<?= YOUR_APP_ID ?>', status: true,
cookie: true, xfbml: true});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
</script>
</body>
</html>
Does anyone know why I am getting this exception? print_r of $user is yielding
stdClass Object ( [error] => stdClass Object ( [type] => OAuthException [message] => An active access token must be used to query information about the current user. ) )
Why is this happening?

一方面， $access_token 在使用之前没有设置？
well for one thing $access_token isn't set before it's used?
