我怎样才能获得代码IDFacebookApiException $e?
我正在使用 Facebook 发帖。但有时却无法发布内容。我正在使用下面的这些代码，并且我在数组中找到了错误响应代码 id$e，但是它们都受到保护，那么我怎样才能获得代码呢？
try{
$facebook->setAccessToken($access_token);
$rs= $facebook->api('/me/feed','POST',$post_data);
} catch (FacebookApiException $e) {
print_r($e);
}
然后我得到错误信息：
FacebookApiException Object

echo "Code: " . $e["error"]["code"];
