参考: https://developers.facebook.com/docs/howtos/login/extending-tokens/
陈述:
默认情况下,大多数访问令牌的有效期有限,通常约为1到2小时。为了在到期后继续使用这些令牌,需要对其进行扩展。
那么为什么在facebook php sdk中给出的所有示例中,登录仅在几分钟后到期,之后需要新的登录?
感谢

这是一个示例的代码(https://github.com/facebook/facebook-php-sdk/blob/master/examples/with_js_sdk.php)
<?php
require '../src/facebook.php';
$facebook = new Facebook(array(
'appId' => '344617158898614',
'secret' => '6dc8ac871858b34798bc2488200e503d',
));
// See if there is a user from a cookie
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
$user = null;
}
}
?>
<!DOCTYPE html>
<html xmlns:fb="http://www.facebook.com/2008/fbml">
<body>
<?php if ($user) { ?>
Your user profile is
<pre>
<?php print htmlspecialchars(print_r($user_profile, true)) ?>
</pre>
<?php } else { ?>
<fb:login-button></fb:login-button>
<?php } ?>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: '<?php echo $facebook->getAppID() ?>',
cookie: true,
xfbml: true,
oauth: true
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
FB.Event.subscribe('auth.logout', function(response) {
window.location.reload();
});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
</body>
</html>
答案 0 :(得分:2)
我最近遇到过这个问题。我认为这与/me
有关,所以我尝试将其更改为/user_id
。这是我使用的代码:
require_once 'facebook-php/src/facebook.php';
$facebook = new Facebook(array(
'appId' => '13********',
'secret' => '7a***********',
));
$userId = $facebook->getUser();
?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head profile="http://gmpg.org/xfn/11">
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '13**********', // App ID
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
};
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script> <?
if ($userId) {
$userInfo = $facebook->api('/' . $userId);
?>
<img src="http://graph.facebook.com/<?php echo $userId; ?>/picture" align="left" width="24px" height="24px" style="padding: 2px 10px 2px 5px"> <div style="margin:0 0 0 0; padding:0 0 0 0; display:inline; height:24px; line-height:28px"><b>Hi there, <?php echo $userInfo['name']; ?>!</b></div>
<? } else { ?>
<div class="fb-login-button" style="display:inline; position:relative; top:3px" scope="email,user_birthday,publish_stream,offline_access"></div>
<? } ?>
</body>
</html>
该代码对我来说是完美的,只要他们登录Facebook就会出现在网站上。
