php - 使用 PHP SDK 在页面上发布 Facebook

Question

我想在页面上发布 - 通过我的网站。 .我没有找到任何可以帮助我的文档。谷歌搜索结果也没有给出我的答案。

function post_facebook($data=null){
        $result = "";
        require_once (ROOT. "/apps/configuration/models/ConfigurationItem.php");
        require_once (ROOT . "/components/facebook/facebook.php");

        $this->ConfigurationItem = new ConfigurationItem($this->getContext());

        $row=$this->ConfigurationItem->findByCatKeyItemKey('system','facebook_login');
        $apiid=$row['value'];

        $row=$this->ConfigurationItem->findByCatKeyItemKey('system','facebook_pass');
        $secret=$row['value'];

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

        $session = $facebook->getSession();
        print_r($session);
        $me = null;
        if ($session) {
            try {
                $uid = $facebook->getUser();
                $me = $facebook->api('/me');
            } catch (FacebookApiException $e) {
                error_log($e);
            }
            $message=$data['facebook_text'];
            $attachment = array(
                'message' => $data['facebook_text'],
                'name' => $data['name'],
                'link' => $this->getLinkToLatestNews(),
                'description' => '',
            );

            if($data['thumb_file_tree_id'] !== NULL) $attachment = $_SERVER['HTTP_HOST']."media/file/image_by_id/".$data['thumb_file_tree_id']."/?w=400&h=500";

            try {
                $facebook->api('/162618213751448/feed/', 'post', $attachment);
                $result = "Facebook: Sent";
            } catch (FacebookApiException $e) {
                $result = "Facebook: Failed";
                error_log($e);
            }
        } else {
            $login_url = $facebook->getLoginUrl();
            header("Location: ".$login_url);
            exit;
        }

        return $result;

    }

错误的部分是:

$session = $facebook->getSession();
$me = null;
if ($session) {
    (...)
} else {
$login_url = $facebook->getLoginUrl();
    header("Location: ".$login_url);
    exit;
}

我想让用户登录指定的 FB 帐户(带有页面)，然后发送。应用程序设置只允许此帐户发帖，所以应该没问题......但不是。当我注销 FB 帐户时， session 仍然存在，但返回异常。怎么了？

如果您想在您是管理员的粉丝页面上发帖.. 执行下一步

1. 您的应用程序至少需要具有此权限:

       $this->loginUrl = $this->facebook->getLoginUrl(
             array(
                   'scope'         => 'manage_pages,offline_access,publish_stream',
                   'redirect_uri'  => $url,
               )
       );
   

2. 登录后:

   //get pages or applications where you are administrator
   $accounts = $this->facebook->api('/me/accounts');
   
   //page where i want to post
   $page_id = '227870047252297';
   
   foreach($accounts['data'] as $account)
   {
      if($account['id'] == $page_id)
      {
         $token = $account['access_token'];
      }
   }
   
   
   $attachment = array(
           'access_token' => $token,
           'message' => 'mensaje',
           'name' => 'titulo',
           'link' => 'http://...',
           'description' => 'xxxxx',
           'picture'=> 'http://...',
   );
   
   
   try{
   $res = $this->facebook->api('/'.$page_id.'/feed','POST',$attachment);
   
   } catch (Exception $e){
   
       echo $e->getMessage();
   }
