Answer 1

他们是在 FB 对象中定义的函数，使用它来销毁 FB session ，

使用(通过 PHP)

$facebook->destroySession();

或者

FB API 提供了一个 logoutURL，它将让用户退出当前的 Facebook 帐户。

你可以像这样使用它，

$facebook = new Facebook($config);
$params = array('next' => 'www.yousite.com/test.php' );
$logoutURL = $facebook->getLogoutUrl($params);

***注意 建议还添加以下代码(以防万一您不希望用户退出您的网站)

//remove PHPSESSID from browser
if ( isset( $_COOKIE[session_name()] ) )
    setcookie( session_name(), '', time()-7000000, '/' );
//clear session from globals
    $_SESSION = array();

通过JS使用自定义事件 引用:(FB.logout() called without an access token. javascript sdk)

function fbLogoutUser() {
    FB.getLoginStatus(function(response) {
        if (response && response.status === 'connected') {
            FB.logout(function(response) {
                document.location.reload();
            });
        }
    });
}
