下面的代码运行良好。它上传一张照片并创建一张新照片。显然，我不知道如何让它重定向到某个地方，它最终会出现一个带有相册id的空白页面。我想放一个重定向链接，在这个重定向链接上应该显示照片。我希望用户在照片上传后被重定向。当用户按下上传按钮时，照片就会被上传。
$post_login_url = "http://apps.facebook.com/firstestt/upload.processor.php";
$album_name = 'Facepic Album';
$album_description = 'http://apps.facebook.com/firstestt/';
$code = $_REQUEST["code"];
$facebook->setFileUploadSupport(true);
//Obtain the access_token with publish_stream permission
if(empty($code))
{
$dialog_url= "http://www.facebook.com/dialog/oauth?"
. "client_id=" . $app_id
. "&redirect_uri=" . urlencode($post_login_url)

echo("<script>top.location.href='" . $dialog_url .

$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$access_token = $facebook->getAccessToken();
// Create a new album
$graph_url = "https://graph.facebook.com/me/albums?"

$postdata = http_build_query(
array(

// Get the new album ID
$album_id = $result->id;

我认为这篇文章完全适合您的需求。
