为什么Python Scrapy显示"twisted.internet.error.TimeoutError""

Question

我试图用python scrapy来删除一个页面。经过一些刮痧手术后，刮痧正在退出

twisted.internet.error.TimeoutError error

这是我的代码：

^{pr2}$

输出如下：

添加延迟后问题解决。在

Answer 2

我发现这个问题也有同样的问题。用户的问题已经自己解决了，我把它贴在这里，这样更容易看到：

设置从站点下载页面之间的延迟可以帮助解决由于对站点的请求过于频繁而导致的超时错误。这是通过项目的设置.py文件。在

The Scrapy documentation这样说：

The amount of time (in secs) that the downloader should wait before downloading consecutive pages from the same website. This can be used to throttle the crawling speed to avoid hitting servers too hard. Decimal numbers are supported. Example:

DOWNLOAD_DELAY = 0.25 # 250 ms of delay
