我有一个要求来聚合来自几个不同的网站(主要是HTML页面和PDF文档)的内容。我目前正在试验Heritrix(3.2.0)以查看它是否能满足我的需求。Heritrix内容过滤

尽管文档非常详细,但引擎似乎并没有像我期望的那样工作。我已经设置了一些简单的工作,并配置了很多不同的方式,但不管我做了什么,我发现Heritrix要么拉下太多的内容,要么什么都不拉。

下面是我想要做的一个例子。我正在将Heritrix指向URL,如... example.com/news/speeches。这是一个带有HTML表格的网页,其中包含指向个人演讲(ex..example.com/news/speech/speech1.html,xample.com/news/speech/speech2.html等)的链接。我真的只需要在父页面下一级的HTML和PDF文档。我希望阻止Heritrix进行比1级更深的导航,如果不低于example.com域上的此特定路径,阻止Heritrix拉动内容,阻止它导航到另一个域,并将其限制为html和pdf内容。

以下配置是什么,我觉得应该工作,但不

我希望我的检索只拉下十几HTML文档作为是所有的包含/语音通道内。大约半小时后,我停止了抓取,因为它正在下载800多个文档,因为我发现它正在向后移动到父级路径。我也尝试了RegEx规则,但没有运气。任何帮助,将不胜感激。

调试此类问题的一件好事是启用作用域决策的日志记录。 (取消注释logToFile并将其设置为true。这将为您的每个URI提供决策包含或拒绝的规则,因此您将能够看到您的规则没有正确配置,并接受应该已被拒绝。
