Is there a way to get a Facebook page's name with PHP?

我正在构建一个iframe应用程序，将有几个提到的Facebook页面上的生活。我的应用程序将被添加到多个页面与不同的名称。我需要的是这样的东西

$page_name = "Bob's Toys";
Thank you for visiting the <?php echo $page_name; ?> page!

有办法做到这一点吗?

有。解码Facebook发送到页面的signed_request

if (!empty($_REQUEST['signed_request'])) {
  $signedRequest = $_REQUEST['signed_request'];
  list($sig, $payload) = explode('.', $signedRequest, 2);
  $data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
}

从中，您可以获得页面的id。

array (size=4)
  'algorithm' => string 'HMAC-SHA256' (length=11)
  'issued_at' => int 1321635439
  'page' => 
    array (size=3)
      'id' => string '19292868552' (length=15)
      'liked' => boolean false
      'admin' => boolean true
  'user' => 
    array (size=3)
      'country' => string 'gb' (length=2)
      'locale' => string 'en_US' (length=5)
      'age' => 
        array (size=1)
          'min' => int 21

然后你可以使用图形API来返回页面对象，看起来像这样:https://graph.facebook.com/19292868552

仅获取页面id，查询仅包含name字段的图形。例如:

<?php
$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"])) {
    $page_info = json_decode(file_get_contents("https://graph.facebook.com/{$data['page']['id']}?fields=name"));
    echo $page_info->name;
}
?>

你可以试试:

$page_profile = $facebook->api('/' . $pageid);
echo "<a href='" . $page_profile['link'] . "'>" . $page_profile['link'] . "</a>";

这对我有用

$page_profile = $facebook->api('/'。美元pageid);

$page_name = $page_profile['name'];
