如何使用nutch 1.2抓取特定URL

Question

我正在使用 nutch-1.2，但无法限制我的配置文件仅抓取给定的 url
我的crawl-urlfilter.txt 文件是

    # Each non-comment, non-blank line contains a regular expression
    # prefixed by '+' or '-'. The first matching pattern in the file
    # determines whether a URL is included or ignored. If no pattern
    # matches, the URL is ignored.

    # skip file:, ftp:, & mailto: urls
    -^(file|ftp|mailto):

    # skip image and other suffixes we can't yet parse
    -\.(gif|GIF|js|jpg|JPG|png|PNG|ico|ICO|css|sit|eps|wmf|zip|ppt|mpg|xls|gz|rpm|tgz|mov|MOV|exe|jpeg|JPEG|bmp|BMP)$

    # skip URLs containing certain characters as probable queries, etc.
    -[?*!@=]

    # skip URLs with slash-delimited segment that repeats 3+ times, to break loops
    -.*(/[^/]+)/[^/]+\1/[^/]+\1/

 # accept hosts in MY.DOMAIN.NAME
    -.*
    +^http://([a-z0-9]*\.)abc.com/[0-9].*[a-z]*.html$
    -^http://([a-z0-9]*\.)*abc.com/[-a-z/]*/$
    -^http://([a-z0-9]*\.)*abc.com/[-a-z]*.php$

谢谢

我想我在某处读到过，这个配置是从上到下评估的。

并且由于

-. 

匹配所有内容 - nutch 将忽略进一步的条目。我的crawl-urlfilter.txt看起来像底部的那样（完全按照这个顺序）并且工作得很好：

# accept hosts in MY.DOMAIN.NAME
+^http://localhost:8080/

# skip everything else
-.
