[英]How to logout only my FBapplication not my facebook account?
I am using facebook javascript sdk on my web application. 我在Web应用程序上使用了Facebook javascript sdk。 I am using graph api to login my application.
我正在使用图形API登录我的应用程序。 When I logged out from my application, my application is logged out and my facebook account is also logout.
当我从应用程序注销时,我的应用程序已注销,并且我的facebook帐户也已注销。

Their is function defined in FB object use this to destroy FB session , 它们是在FB对象中定义的功能,以此破坏FB会话,
usage( via PHP) 用法(通过PHP)
$facebook->destroySession();
Or 要么
FB API provides a logoutURL which will log the user out of their current Facebook account. FB API提供了一个logoutURL,它将使用户退出当前的Facebook帐户。
you can use it like this , 您可以这样使用它,
$facebook = new Facebook($config);
$params = array('next' => 'www.yousite.com/test.php' );
$logoutURL = $facebook->getLogoutUrl($params);
***note advisable to add below codes also (not in case if you dont want your user to log out of your site) ***请注意也建议添加以下代码(如果您不希望用户退出您的网站,则不要这样做)
//remove PHPSESSID from browser
if ( isset( $_COOKIE[session_name()] ) )
setcookie( session_name(), '', time()-7000000, '/' );
//clear session from globals
$_SESSION = array();
With JS using a custom event ref : ( FB.logout() called without an access token. javascript sdk ) 使用自定义事件ref的JS :(调用FB.logout(),而没有访问令牌。javascript sdk )
function fbLogoutUser() {
FB.getLoginStatus(function(response) {
if (response && response.status === 'connected') {
FB.logout(function(response) {
document.location.reload();
});
}
});
}
