带有noindex nofollow的Stormcrawler页面被爬网

问题描述

我们正在使用Stormcrawler 1.13来爬网站点页面。在一个环境中使用时，不是在爬网具有机械手Meta noindex nofollow的页面，而是在另一个环境中部署相同的模块时，也会对具有noindex nofollow的页面进行爬网。以下是我们的crawler-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.
# This file does not contain all the key values but only the most frequently used ones. See crawler-default.xml for an extensive list.

请告诉我是否需要对上述代码或Storm Crawler中的任何其他配置进行一些更改。

谢谢。

解决方法

在1.13中无法配置meta noindex的行为，因此环境之间的任何差异都不能归因于配置差异。

您是如何生成拓扑的？您使用原型吗？

PS：设置 http.agent。 *配置是一个好习惯。
