我正在从Yelp上抓取餐厅 comments ，我正在访问餐厅的API来这样做.我目前正在收集4个星级 comments ，例如这restaurant page个有对应的API个.
这是当爬虫程序当前位于餐厅页面上时向API发送http请求的代码块
bizId = response.xpath("//meta[@name='yelp-biz-id']/@content").extract_first()
api_url = 'https://www.yelp.it/biz/' + bizId + '/review_feed?rr=' + str(n_star_filter)
yield response.follow(url=api_url, callback = self.parse_yelp_restaurant_api)
有时API被正确访问，我能够刮取它们.但是，大多数时候，我会得到这样的错误:

我不明白这是什么意思，这真的很奇怪，一些API被下载，而另一些API在它们看起来没有什么不同的时候产生这个错误.
