Facebook登錄使用Javascript和PHP

我一直試圖解決這個問題，現在幾天了，但似乎無法理解我做錯了什麼。這個想法是讓用戶使用Javascript登錄並在通過PHP進行重新驗證之前，在數據庫中輸入用戶的信息，但它一直說「沒有設置cookie或不能從cookie獲取OAuth數據」。Facebook登錄使用Javascript和PHP

的index.php：

var appLoginFlag = false; 
    var appAccessToken = null; 

    window.fbAsyncInit = function() { 
     FB.init({ 
      appId: 'xxxxxxxxx', 
      cookie: true, 
      status: true, 
      xfbml: true, 
      oauth: true, 
      version: 'v2.2' 
     }); 

     checkLoginState(); 
    }; 

    function statusChangeCallback(response) { 
     if (response.status === 'connected') { 
      appLoginFlag = true; 
      if (response.authResponse) { 
       console.log(response.authResponse); 
       FB.api('/me?fields=id,name,first_name,last_name,email', function(response) { 
        console.log('Email: ' + response.email); 
        console.log('Name: ' + response.name); 
        $.ajax({ 
         type: "POST", 
         url: "user_insert.php", 
         success: function(result) { 
          document.getElementById('login-wrap').innerHTML = 'Hi <strong>' + response.first_name + '</strong>!'; 
         } 
        }); 
       });       
      } 
     } 
     else { 
      console.log(response.status); 
      appLoginFlag = false; 
     } 
    } 

    function checkLoginState() { 
     FB.getLoginStatus(function(response) { 
      statusChangeCallback(response); 
     }); 
    } 

    (function(d, s, id){ 
     var js, fjs = d.getElementsByTagName(s)[0]; 
     if (d.getElementById(id)) { 
      return; 
     } 
     js = d.createElement(s); 
     js.id = id; 
     js.src = "//connect.facebook.net/en_US/sdk.js"; 
     fjs.parentNode.insertBefore(js, fjs); 
    } (document, 'script', 'facebook-jssdk')); 

    function FBLogin() { 
     FB.login(function(response) { 
      FB.api("/me/feed", "post", {message: "Some message"}, statusChangeCallback(response)); 
     }, 
     {scope: 'public_profile, email, publish_actions' 
     }); 
    }

user_insert.php：

<?php session_start(); 
    require_once __DIR__ . '/facebook-sdk-v5/autoload.php'; 

    $fb = new Facebook\Facebook([ 
     'app_id' => 'xxxxxxxxxxxxxx', 
     'app_secret' => 'xxxxxxxxxxxxxxxxxxxx', 
     'default_graph_version' => 'v2.2', 
    ]); 

    $helper = $fb->getJavaScriptHelper(); 

    try { 
     $accessToken = $helper->getAccessToken(); 
    } catch(Facebook\Exceptions\FacebookResponseException $e) { 
     echo 'Graph returned an error: ' . $e->getMessage(); 
     exit; 
    } catch(Facebook\Exceptions\FacebookSDKException $e) { 
     echo 'Facebook SDK returned an error: ' . $e->getMessage(); 
     exit; 
    } 

    if (! isset($accessToken)) { 
     echo 'No cookie set or no OAuth data could be obtained from cookie.'; 
     exit; 
    } 

    echo '<h3>Access Token</h3>'; 
    var_dump($accessToken->getValue()); 

    $_SESSION['fb_access_token'] = (string) $accessToken; 

    // Now you can redirect to another page and use the 
    // access token from $_SESSION['facebook_access_token'] 

    // instructions to insert into database 
?>

最後，這樣做是正確。問題出在API版本上。在我的Facebook應用程序面板中，當我編碼爲V2.2時，我的版本爲V2.4。
