我有以下代码,我认为非常接近工作,但我不断收到以下错误：
{"error":{"message":"(#324) Requires upload file","type":"OAuthException"}}
但我无法弄清楚如何指定上传文件…我尝试了图像和源,都给出了同样的错误.任何想法,帮助,建议都会非常感激,因为我已经在这几天苦苦挣扎,似乎不应该这么难……

解决方法:
在创建Facebook类的新实例时,您需要将config var fileUpload设置为true,如documentation here和here中所述.您还需要photo_upload权限;-)
require_once("facebook.php");
$config = array();
$config[‘appId’] = 'YOUR_APP_ID';
$config[‘secret’] = 'YOUR_APP_SECRET';
$config[‘fileUpload’] = true; // <-- set this to 'true' otherwise it won't work
$facebook = new Facebook($config);
