Goutte / GuzzleHTTP获取响应正文的内容长度/大小

I am using https://github.com/FriendsOfPHP/Goutte to scrape a page. No probs there.

I am trying to get the Content-Length from the client response object, but cannot see how I can do this.

Clicking through the docs... Use $response = $client->getInternalResponse() to get a Symfony\Component\BrowserKit\Response which as a $response->getHeader('Content-Length') available. :-)
