Question

我正在使用facebook的php SDK，而我正试图在由登录用户管理/管理的页面上发布。我已经授予了publish_stream和manage_pages权限。我希望帖子应该看起来像是由页面而不是管理员或登录用户。我尝试了几个帮助，但没有人工作。这是我现有代码的一部分：

require './php-fb-sdk/facebook.php';

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

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

// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.

if ($user) {
    try {
        // Proceed knowing you have a logged in user who's authenticated.
        $user_profile = $facebook -> api('/me');
    } catch (FacebookApiException $e) {
        error_log($e);
        $user = null;
    }
}

$params = array("scope" => array("manage_pages", "publish_stream"));
// Login or logout url will be needed depending on current user state.
if ($user) {
    // Fetch the viewer's basic information
    $basic = $facebook -> api('/me');

    $permissions = $facebook -> api("/me/permissions");
    if (array_key_exists('manage_pages', $permissions['data'][0]) && array_key_exists('publish_stream', $permissions['data'][0])) {

        $admin_pages = $facebook -> api(array('method' => 'fql.query', 'query' => "SELECT page_id, type from page_admin WHERE uid=me() and type!='APPLICATION'"));
        if (count($admin_pages) > 0) {

            $post_info = $facebook -> api('/' . $admin_pages[0]["page_id"] . '/feed', 'post', array("caption" => "From web", "message" => "This is from my web at: " . time()));
            echo '<hr>The post info is: ' . print_r($post_info, true) . '<hr>';
        } else {
            echo '<hr> You are not admin of any fb fan page<hr>';

        }
        //print_r($admin_pages);

    } else {
        // We don't have the permission
        // Alert the user or ask for the permission!
        header("Location: " . $facebook -> getLoginUrl(array("scope" => "manage_pages,publish_stream")));
    }
    $logoutUrl = $facebook -> getLogoutUrl();
} else {
    //$statusUrl = $facebook->getLoginStatusUrl();
    $loginUrl = $facebook -> getLoginUrl($params);
    $statusUrl = $loginUrl;
}

使用上面的代码我可以在页面上发布，但它看起来像是由用户制作的。

但是，如果我使用facebook JS SDK，那么我看到帖子看起来就像是由页面制作的。

var data=
            {
                caption: 'My Caption',
                message: 'My Message'
            }

            FB.api('/' + pageId + '/feed', 'POST', data, onPostToWallCompleted);
            }

非常感谢任何帮助或建议。

要代表网页在网页上发帖，您需要使用页面访问令牌。您当前的电话：

$facebook -> api('/' . $admin_pages[0]["page_id"] . '/feed', 'post', array("caption" => "From web", "message" => "This is from my web at: " . time()));

正在使用默认（用户）访问令牌。

要获取页面访问令牌，请在发布post：

之前进行此调用

\GET /{page-id}?fields=access_token

这会在结果中为您提供一个页面访问令牌，然后只需使用它来进行发布Feed调用，就像这样 -

$facebook -> api(
  '/' . $admin_pages[0]["page_id"] . '/feed', 
  'post', 
  array(
    "caption" => "From web", 
    "message" => "This is from my web at: " . time(),
    "access_token" => '{page_access_token}'
  )
);

（如果需要，您还可以获得页面永不过期的令牌，请点击此处查看：What are the Steps to getting a Long Lasting Token For Posting To a Facebook Fan Page from a Server）
