我编写了一个蜘蛛来从 http://allevents.in 获取详细信息。 每次我尝试废弃时,我都会收到响应正文
Too many requests, please try after some time or report this problem at <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="43202c2d3722203703222f2f2635262d37306d2a2d" rel="noreferrer noopener nofollow">[email protected]</a>
我也尝试过使用 shell 命令。
scrapy shell 'http://allevents.in/new%20delhi/all'
但我仍然收到与 response.body
相同的响应。
我尝试过其他网站,例如 amazon效果很好。
另外,可以使用 requests
以及 urllib.urlopen()
获取上述 url。
这是我的settings.py

我是 scrapy 的初学者。请帮忙
最佳答案
Scrapy 使用多个并发请求(默认为 8 个)来抓取您指定的网站。看来 allevents.in 不喜欢你点击太多。
您的解决方案很可能是设置以下配置选项之一:
CONCURRENT_REQUESTS_PER_DOMAIN
(默认为 8,尝试使用较小的数字)CONCURRENT_REQUESTS_PER_IP
(默认为 0,如果设置为正数,则覆盖前一个)
或者,您也可以使用 AutoThrottle extension .
关于python - 使用 scrapy 抓取特定网站时出现 "Too many requests"错误,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/47093405/
