Question

我正在我的页面上创建用户登录，并选择使用Facebook使用PHP SDK登录。我遇到的问题是Facebook离开我的网站，获得用户和Facebook的许可，然后回到我的网站。一切正常，因为它应该，但令牌的Facebook会创建存储在URL，如www。############ /帐号/ register.php？代码= AQDEN90jFQLsDPS5UEXOWCBItXfs5uVbKDs2AfZmV5d7nIHTNy6IXUXtDX-BJMxh6wlsC6-QoOzxnGCLqD_lG4Ui0HF5eUwLP15fUrAgwrwDLHcmRUKrvIcgHOOxr61u6E8me1EV7-VAHiRXG- d-U7qi8fWS7fYpU5OOjGctdzoOvx9Vl35NpXbbALq＆安培;状态= 5659508109f2207707c8＃ =

如果用户在被重定向后刷新该页面，它会将整个内容搞砸，因为它再次重新提交令牌，这会引发php facebook错误并结束代码链。

我的代码如下。

//1.Use app id,secret and redirect url
 $app_id = '###################';
 $app_secret = '#########';
 $redirect_url='http://#####account/register.php';

 //2.Initialize application, create helper object and get fb sess
 FacebookSession::setDefaultApplication($app_id,$app_secret);
 $helper = new FacebookRedirectLoginHelper($redirect_url);
 $sess = $helper->getSessionFromRedirect();

     //check if facebook session exists
if(isset($_SESSION['fb_token'])){
    $sess = new FacebookSession($_SESSION['fb_token']);
}
    //logout
$logout = 'http:/########/includes/fblogin/lib/Facebook/FbLogout.php';
//3. if fb sess exists echo name 
    if(isset($sess)){
                //store the token in the php session
    $_SESSION['fb_token']=$sess->getToken();
        //create request object,execute and capture response
    $request = new FacebookRequest($sess, 'GET', '/me');
    // from response get graph object
    $response = $request->execute();
    $graph = $response->getGraphObject(GraphUser::className());
    $name = $graph->getName();
    $id = $graph->getId();
    $image = 'https://graph.facebook.com/'.$id.'/picture';
    $email = $graph->getProperty('email');
    echo "hi $name <br>";
    echo "your email is $email <br><Br>";
    echo "<img style='width: 50px; border-radius: 4px;' src='$image' /><br><br>";
    echo "<a href='".$logout."'>Logout</a>";
}else{
    //else echo login
    echo '<a href='.$helper->getLoginUrl().'>Login with facebook</a>';
}

那么，如何在从facebook返回时将请求令牌存储在$ sess变量中，然后清除该URL以便用户无法使用该URL中的该字符串进行刷新？
