如何在 PHP 中获取 Facebook 访问令牌，同时在 JS 中使用 oauth2？

我在网站上使用 FB 连接和 Facebook 的登录按钮。

我使用它登录，然后在登录时重新加载页面，我尝试在 PHP 中获取具有 access_token 的 cookie，但未能成功。以下是我的js代码：

window.fbAsyncInit = function() {
      FB.init({
        appId      : 'xxxxxxxx',
        status     : true, 
        cookie     : true,
        xfbml      : true,
        oauth      : true
      });

      FB.Event.subscribe('auth.login', function(response) {
        window.location.reload();
      });
    };
    (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));

Facebook登录按钮代码：

<div class="fb-login-button" scope="email,user_checkins" >Login with Facebook</div>

现在，当用户使用facebook登录时，我尝试使用access_token获取其数据，但没有从cookie中获取access_token。我正在使用以下代码：

$cookie = $this->get_facebook_cookie(APP_ID, APP_SECRET);



        echo $cookie['access_token'];
        if(isset($cookie['access_token'])){  

            $user = json_decode(@file_get_contents('https://graph.facebook.com/me?access_token=' .$cookie['access_token']));
            echo $user->id;
            if(isset($user->id)){
             //       my stuff

            }                    
        }

我怀疑它甚至没有获取 cookie。当它在客户端登录时。那么如何在 PHP 中获取数据呢？还需要在 PHP 端再次重复整个登录过程吗？我该如何处理？

原文

I am using FB connect and login button of facebook on a site.

I logged in using it and then on login, I reload the page, I tried to get the cookie having access_token in PHP but failed to do so. Following is my js code:

window.fbAsyncInit = function() {
      FB.init({
        appId      : 'xxxxxxxx',
        status     : true, 
        cookie     : true,
        xfbml      : true,
        oauth      : true
      });

      FB.Event.subscribe('auth.login', function(response) {
        window.location.reload();
      });
    };
    (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));

Fb login button code:

<div class="fb-login-button" scope="email,user_checkins" >Login with Facebook</div>

Now I when user login using facebook, I try to get its data using access_token, but not getting that access_token from cookies.
I am using following code:

$cookie = $this->get_facebook_cookie(APP_ID, APP_SECRET);



        echo $cookie['access_token'];
        if(isset($cookie['access_token'])){  

            $user = json_decode(@file_get_contents('https://graph.facebook.com/me?access_token=' .$cookie['access_token']));
            echo $user->id;
            if(isset($user->id)){
             //       my stuff

            }                    
        }

I doubt it is not even getting cookie. While it logged at client side. So how can I get data in PHP then? need to again repeat whole login process on PHP side too? How do I deal with it?
