在运行的时候不会抓取到,分析了一下原因:主要在conf/crawl-urlfilter.txt.
分析:使用nutch默认的配置过滤文件的话,是不抓取到包含?*!@=等字符的URL
解决办法:修改crawl-urlfilter的过滤规则,
# The url filter file used by the crawl command.
# Better for intranet crawling.
# Be sure to change MY.DOMAIN.NAME to your domain name.
# 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|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.
-[?*!@=] //表示过滤包含指定字符的URL,改为: -[~]
# skip URLs with slash-delimited segment that repeats 3+ times, to break loops
