我们使用Stormccrawler 1.13来抓取网站页面。当在一个环境中使用时，它不会对具有robots meta noindex nofollow的页面进行爬网，但当我们在另一个环境下部署相同的模块时，也会对具有noindex nofollow的页面执行爬网。下面是我们的爬网程序conf.yaml.
# Custom configuration for StormCrawler
# This is used to override the default values from crawler-default.xml and provide additional ones
# for your custom components.
# Use this file with the parameter -conf when launching your extension of ConfigurableTopology.

如果需要对上面的代码或风暴爬行器中的任何其他配置进行一些更改，请告诉我。
谢谢。
meta noindex的行为在1.13中是不可配置的，因此您的环境之间的任何差异都不可能是由于配置的差异。
您是如何生成拓扑的？你用原型了吗？
PS：最好设置http.agent。*配置。
