nutch 0.9二次开发--抓不到包含?等符号的URL

nutch 0.9二次开发--抓不到包含?等符号的URL

问题：使用nutch抓取不到http://www.tianya.cn/new/TianyaCity/content.asp?idItem=296&idArticle=53561&idWriter=0&key=0等URL

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
-.*(/.+?)/.*?\1/.*?\1/

# accept hosts in MY.DOMAIN.NAME
+^http://([a-z0-9]*\.)*tianya.cn/[\s\S]*    // 过滤正则表达式，([a-z0-9]*\.)*表示任意数字和字母，[\s\S]*表示任意字符

# skip everything else
-.
