Podio PHP API＆gt;获取项目修订版差异

Question

您好我使用https://github.com/podio/podio-php与Podio API进行通信，问题是https://developers.podio.com/doc/items/get-item-revision-difference-22374无效......不知道为什么......

我的代码：

$client_id = "xxx";
$client_secret = "xxx";
$app_id = "xxx";
$app_token = "xxx";

Podio::setup($client_id, $client_secret);

try {
  Podio::authenticate_with_app($app_id, $app_token);
  $item_id = "xxx";
  $revision_from_id = 0;
  $revision_to_id = 1;
  $showDiff = PodioItemDiff::get_for( $item_id, $revision_from_id, $revision_to_id );

  echo $showDiff;

}
catch (PodioError $e) {
  // Something went wrong. Examine $e->body['error_description'] for a description of the error.
}

页面上的结果：

阵列

有人可以帮助我吗？
