作爲頁面發佈在Facebook牆上，而不是用戶

Question

是否可以作爲應用程序發佈在Facebook牆上而不是用戶？據我瞭解，應用程序不是Facebook的有效用戶，但有許多關於發佈爲頁面而不是用戶或應用程序的評論。

我該如何使用PHP Facebook API來做到這一點？

Answer 1

您必須先通過Facebook連接授予用戶授權，並請求manage_pages權限作爲此請求的一部分。您可以使用此權限爲相關頁面獲取令牌和祕密。然後，您使用這些來授權請求​​，而不是您爲用戶收到的令牌/祕密。

看看這個頁面的一些額外信息「頁面登錄」部分： http://developers.facebook.com/docs/authentication/

Answer 2

您需要publish_stream,manage_pages權限。該代碼是這樣的：

<?php 
// This code is just a snippet of the example.php script 
// from the PHP-SDK <https://github.com/facebook/facebook-php-sdk/blob/master/examples/example.php> 
require '../src/facebook.php'; 

// Create our Application instance (replace this with your appId and secret). 
$facebook = new Facebook(array(
    'appId' => 'app_id', 
    'secret' => 'app_secret', 
)); 

// Get User ID 
$user = $facebook->getUser(); 

if ($user) { 
    try { 
    $page_id = 'page_id'; 
    $page_info = $facebook->api("/$page_id?fields=access_token"); 
    if(!empty($page_info['access_token'])) { 
     $args = array(
      'access_token' => $page_info['access_token'], 
      'message'  => "I'm a Page!" 
     ); 
     $post_id = $facebook->api("/$page_id/feed","post",$args); 
    } else { 
     $permissions = $facebook->api("/me/permissions"); 
     if(!array_key_exists('publish_stream', $permissions['data'][0]) || 
      !array_key_exists('manage_pages', $permissions['data'][0])) { 
      // We don't have one of the permissions 
      // Alert the admin or ask for the permission! 
      header("Location: " . $facebook->getLoginUrl(array("scope" => "publish_stream, manage_pages"))); 
     } 

    } 
    } catch (FacebookApiException $e) { 
    error_log($e); 
    $user = null; 
    } 
} 

// Login or logout url will be needed depending on current user state. 
if ($user) { 
    $logoutUrl = $facebook->getLogoutUrl(); 
} else { 
    $loginUrl = $facebook->getLoginUrl(array('scope'=>'manage_pages,publish_stream')); 
} 

// ... rest of your code 
?>
