使用PHP和JS SDK的Facebook注销
[英]Facebook Logout with PHP and JS SDK
问题描述
I have the following code (with my facebook.php correctly added in, appId and appSecret are also correct): 
我有以下代码（正确添加了我的facebook.php ， appId和appSecret也正确）：
<?php
define('APP_ID', 'XXX');
$facebook = new Facebook(array(
'appId' => APP_ID,
'secret' => 'XXX',
));
$userId = $facebook->getUser();
?>
<html>
<body>
<div id="fb-root"></div>
<?php if ($userId) {
$userInfo = $facebook->api('/' + $userId); ?>
Welcome <?= $userInfo['email'] ?> <fb:logout-button></fb:logout-button>
<?php } else { ?>
<div id="fb-root"></div>
<fb:login-button></fb:login-button>
<?php } ?>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '<?= APP_ID ?>',
status : true,
cookie : true,
xfbml : true,
oauth : true,
});
FB.logout(function()
{
top.location.href = 'http://www.google.com'
});
};
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
My code always outputs Welcom myemail@email.com . 我的代码始终输出myemail@email.com 。 How do I get it to logout correctly so that I can test it to login again? 我如何使其正确注销，以便可以对其进行重新登录进行测试？

Delete cookies, session, etc. Then with the facebook API do something like this: 删除cookie，会话等。然后使用facebook API执行以下操作：
$logoutUrl = $facebook->getLogoutUrl(array('next' => $_SERVER['HTTP_REFERER'], 'session_key' => $fb_session['session_key']));
$fb_session = $facebook->setSession(null);
header('Location:' . $logoutUrl);
If you want the user to go back to a specific page just change the 'next' value to whatever page you want them to go back to. 如果您希望用户返回到特定页面，只需将“下一个”值更改为您希望他们返回的任何页面。

$fb_session = $facebook->setSession(null);
@Somnath Muluk , it seems this code will clear the session, so not just the fb app will logout, the facebook website loginstatus also will be clear. @Somnath Muluk，似乎这段代码将清除会话，因此不仅fb应用程序将注销，Facebook网站的loginstatus也将清除。
But i think the app-logout-option will just let the app logout of fb. 但是我认为app-logout-option只会让fb退出应用程序。 when I continue to visit my fb feeds it should work without let me do the login option again 当我继续访问我的fb feed时，它应该可以正常工作，而无需让我再次执行登录选项
