Facebook登陆页面在被喜欢后发生变化

Question

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？

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

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

}

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。是将HTML代码插入到index.php文件中，还是有对对象的调用。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,
));
?>

<title>Welcome Page</title>
</head>
<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 -->
<? } ?>
