Php 如何使用graph API将照片上载到相册

我的代码（不工作）：

---

有人能指出我的错误吗？提前感谢。

查看facebook的howto:

确保服务器端启用了文件上载，并按照页面上的说明将

fileUpload

设置为

true

初始化SDK，或者调用。您不需要像上面所做的那样使用访问令牌和

curl

命令手动调用graph API，PHP SDK将为您解决这一问题。有关完整示例，请参见本页

<?php
require '../src/facebook.php';
$facebook = new Facebook(array(
  'appId'  => '...',
  'secret' => '...'
));

Facebook::$CURL_OPTS[CURLOPT_SSL_VERIFYPEER] = false; 
$user = $facebook->getUser();
if ($user) {
  try {
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

if ($user) {
  $album_id = '246592692052269';    
  $FILE_PATH = 'Language.jpg';
  $access_token = $_SESSION['fb_appId_access_token'];
  $logoutUrl = $facebook->getLogoutUrl();
   $args = array('image'=> '@' . __DIR__.$FILE_PATH, 
           'name' => 'this photo was taken in acre',
          'message'=> 'Photo Caption'); 
    $ch = curl_init();
    $url = 'http://graph.facebook.com/'.$album_id.'/photos?access_token='.$access_token;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
    $data = curl_exec($ch);
    //returns the photo id
    if(empty($data)) {
    echo 'Responde: '. $data . '<pre>';
    print_r(curl_getinfo($ch));
    echo '</pre>';
    } else {
    echo 'Upload failed! erro='. curl_error($ch);
    }

} else {
  $loginUrl = $facebook->getLoginUrl();
}

?>
