Php 通过ajax在facebook应用程序中加载页面

我已经创建了一个facebook应用程序，用作页面标签。我使用的是PHPSDK和JavaScriptSDK，并对其进行了身份验证和完美设置，以便在选项卡iframe中显示对话框和我的页面

我现在想异步加载我站点的其他页面，但是我无法访问异步加载页面上的用户数据（名称等）。如何将身份验证和变量传递给ajax加载的页面

（编辑）解决方案：

PHPSDK自动创建一个会话，以便在加载了ajax的页面（或任何地方）之间使用。为了访问数据，您只需在加载了ajax的每个页面上调用您的身份验证例程（最好使用php include）

我使用简单的jquery加载将页面加载到div中：

$('div#page').load('your-page.php');

这是我在每个php页面上运行的例程：

<?php
    //facebook application configuration
    $fbconfig['appid' ] = "YOUR APP ID";
    $fbconfig['secret'] = "YOUR APP SECRET";

    $fbconfig['baseUrl']    =   "SOURCE FILES BASE URL";
    $fbconfig['appBaseUrl'] =   "APP BASE URL";

    /* 
     * If user first time authenticated the application facebook
     * redirects user to baseUrl, so I checked if any code passed
     * then redirect him to the application url 
     */
    if (isset($_GET['code'])){
        header("Location: " . $fbconfig['appBaseUrl']);
        exit;
    }

    //
    if (isset($_GET['request_ids'])){
        //user comes from invitation
        //track them if you need
    }

    $user =   null; //facebook user uid
    try{
        include_once "facebook.php";
    }
    catch(Exception $o){
        echo '<pre>';
        print_r($o);
        echo '</pre>';
    }
    // Create our Application instance.
    $facebook = new Facebook(array(
      'appId'  => $fbconfig['appid'],
      'secret' => $fbconfig['secret'],
      'cookie' => true,
    ));

    //Facebook Authentication part
    $user = $facebook->getUser();
    // We may or may not have this data based 
    // on whether the user is logged in.
    // If we have a $user id here, it means we know 
    // the user is logged into
    // Facebook, but we don’t know if the access token is valid. An access
    // token is invalid if the user logged out of Facebook.

    $loginUrl = $facebook->getLoginUrl(
            array(
                'scope' => 'email,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown'
            )
    );

    if ($user) {
      try {
        // Proceed knowing you have a logged in user who's authenticated.
        $user_profile = $facebook->api('/me');

      } catch (FacebookApiException $e) {
        //you should use error_log($e); instead of printing the info on browser
        d($e);  // d is a debug function defined at the end of this file
        $user = null;
      }
    }

    if (!$user) {
        echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
        exit;
    }

    //get user basic description
    $userInfo = $facebook->api("/$user");

    function d($d){
        echo '<pre>';
        print_r($d);
        echo '</pre>';
    }
?>

这取决于您如何执行请求，但您可以将数据保存在$\u会话变量中，如$\u会话['userData']=$facebook->api（'/me'）；在每一页上都能看到
