作为页面发布在Facebook墙上，而不是用户

Question

是否可以作为应用程序发布在Facebook墙上而不是用户？据我了解，应用程序不是Facebook的有效用户，但有许多关于发布为页面而不是用户或应用程序的评论。

我该如何使用PHP Facebook API来做到这一点？

Answer 1

您必须先通过Facebook连接授予用户授权，并请求manage_pages权限作为此请求的一部分。您可以使用此权限为相关页面获取令牌和秘密。然后，您使用这些来授权请求​​，而不是您为用户收到的令牌/秘密。

看看这个页面的一些额外信息“页面登录”部分： http://developers.facebook.com/docs/authentication/

Answer 2

您需要publish_stream,manage_pages权限。该代码是这样的：

<?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 
?>
