Facebook登陆页面在被喜欢后发生变化

Question

am trying to show users who liked my page a different page, am using this code but it doesnt seem to be working, can anyone help? 试图向喜欢我的页面的用户显示其他页面，正在使用此代码，但似乎不起作用，有人可以帮忙吗？

basically it should show the main index.html as the landing page then when people click the like button it will show the fans_only.html page to welcome the users after they like the page. 基本上，它应该显示主要的index.html作为登录页面，然后当人们单击“赞”按钮时，它将显示fans_only.html页面，在用户喜欢该页面后欢迎他们。

<?php
require_once 'facebook/facebook.php';
/*
 * "appId" and "secret" values get from your Facebook application settings
 */
$config = array (
    'appId' => 'xxx',
    'secret' => 'xxx'
);
$facebook = new Facebook ($config);
{

    $signed_request = $facebook->getSignedRequest();

    if ($signed_request)
    {
        if (isset ($signed_request ['page'] ['liked']) && $signed_request ['page'] ['liked'])
        {
            //Place your secret content here
            //echo '<p>This is a secret content.</p>';
            require ("fans_only.html");
            exit;
        }
    }
}
?>

Answer 1

Try this code: 试试这个代码：

$facebook = new Facebook(array(
  'appId'  => 'APP_ID',
  'secret' => 'APP_SECRET',
  'cookie' => true,
));

$session = $facebook->getSession();

$me = null;

if ($session) {
  try {
    $uid = $facebook->getUser();
    $me = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
  }
}


$signed_request = $_REQUEST["signed_request"];

function parse_signed_request($signed_request, $secret) {
  list($encoded_sig, $payload) = explode('.', $signed_request, 2);

  // decode the data
  $sig = base64_url_decode($encoded_sig);
  $data = json_decode(base64_url_decode($payload), true);

  if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') {
    error_log('Unknown algorithm. Expected HMAC-SHA256');
    return null;
  }

  // check sig
  $expected_sig = hash_hmac('sha256', $payload, $secret, $raw = true);
  if ($sig !== $expected_sig) {
    error_log('Bad Signed JSON signature!');
    return null;
  }

  return $data;
}

function base64_url_decode($input) {
  return base64_decode(strtr($input, '-_', '+/'));
}

$data = parse_signed_request($_REQUEST["signed_request"], "APP_SECRET");


if ($data['page']['liked']){

  //SHOW DATA FAN

}else{

   //SHOW DATA NO FAN

}

Answer 2

I am trying to set up a welcome page (fan/nofan) pages using similar code, but as a noobie, I am missing a step as to how the program (the index.php file) knows what page to display and where that page is. 我正在尝试使用类似的代码来建立一个欢迎页面（fan / nofan）页面，但是作为一个noobie，我缺少有关程序（index.php文件）如何知道要显示哪个页面以及该页面在哪里的步骤是。 Is the HTML code inserted into the index.php file or is there a call to an object. 是将HTML代码插入到index.php文件中，还是有对对象的调用。 Here is the facebook sdk set up for two different welcome pages. 这是为两个不同的欢迎页面设置的facebook sdk。

<?php
require_once './facebooksdk/src/facebook.php';  //download at https://github.com/facebook/php-sdk/downloads

$facebook = new Facebook(array(
  'appId' => '174968482618267', // enter your App's ID
  'secret' => '5710d00a9b4acec8849d8adeb08c15c4', // enter your App's Secret
  'cookie' => true,
));
?>

<body>

<?php
// Did they like a page?
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);

if (empty($data["page"]["liked"])) {
// DISPLAY TO: those who didn't LIKE the page
    ?>


<!-- Didn't Like -->

You don't "Like" our page :-(

<!-- End of Didn't Like -->
    <?
} else {
// DISPLAY TO: those who LIKED the page
    ?>

<!-- Liked -->

Thanks for "Liking" our page!

<!-- End of Liked -->
<? } ?>
