将照片发布到FB导致需要上传文件错误

标签: php facebook facebook-graph-api upload photo

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...我尝试了图片和来源,两者都给出了同样的错误。任何想法,帮助和建议都会非常感激,因为我已经在这几天苦苦挣扎,似乎不应该这么难......

documentation herehere所述,您需要在创建Facebook类的新实例时将config var fileUpload设置为true。而且你还需要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);

您在Graph API调用中使用文件名而不是文件本身。

您应该在文件名前加上@

$args = array( 'message' => $photo_message,
    'image' => '@'.$photo_source
);
