Question

我正在尝试使用自定义中间件记录每个请求使用的带宽。使用以下代码

class CustomDownloaderMiddleware(CustomMiddleware):
    def process_response(self, request, response, spider):
        if response.url.startswith("http"):
            logging.info("{}: {}".format(response.url,len(response.body)))
            
        return response

我正在寻找的不是身体尺寸，而是带宽。但是我在response.headers中找不到Content-Length。有什么办法吗？
