I have investigated how to rewrite urls.. and have made this code.
It rewrites urls from "show-all.html" to "show.cgi?all".
And from "show-abcd.html" to "show.cgi?first=a;last=d".
I hope its usable.
require "webrick"
class WEBrick::HTTPServer
alias :old_initialize :initialize
alias :old_service :service
def initialize(config={}, default=WEBrick::Config::HTTP)
old_initialize(config, default)
@rewrite_rules = []
end
def rewrite(pattern, subst)
@logger.debug("rewrite rule %s -> %s." %
[pattern.inspect, subst])
@rewrite_rules << [pattern, subst]
end
def service(req, res)
path = req.path
@rewrite_rules.each do |pattern, subst|
if pattern =~ path
new_path = path.gsub(pattern, subst)
@logger.debug("rewrote url from %s to %s" % [path, new_path])
req.instance_variable_set("@path", new_path)
# TODO: req.query = reload
break
end
end
old_service(req, res)
end
end
class PageServlet < WEBrick::HTTPServlet::AbstractServlet
def do_GET(req, res)
ary = [
["path", req.path],
["path_info", req.path_info],
["request_uri", req.request_uri.inspect],
["unparsed_uri", req.unparsed_uri.inspect],
["query", req.query.inspect],
["query_string", req.query_string.inspect]
]
rows = ary.map{|line|
cells = line.map{|cell| "<td>#{cell}</td>"}.join
"<tr>#{cells}</tr>"
}.join
str = "<table>#{rows}</table>"
res.body = "<html><body>#{str}</body></html>"
res['Content-Type'] = "text/html; charset=iso-8859-1"
end
end
if $0 == __FILE__
s = WEBrick::HTTPServer.new(
:Port => 10080,
:Logger => WEBrick::Log.new($stderr, WEBrick::Log::DEBUG),
:AccessLog => [
[ $stderr, WEBrick::AccessLog::COMMON_LOG_FORMAT ],
[ $stderr, WEBrick::AccessLog::REFERER_LOG_FORMAT ],
[ $stderr, WEBrick::AccessLog::AGENT_LOG_FORMAT ],
]
)
s.mount("/", PageServlet)
s.mount("/show.cgi", PageServlet)
s.rewrite(/show-all.html(?=$|\?)/, "show.cgi?all")
s.rewrite(/show-abcd.html$/, "show.cgi?first=a;last=d")
trap(:INT) do
#fork{ s.shutdown }
exit!
end
s.start
