Question

我正在使用RubyDNS。当我使用匹配块时，我想在匹配中跳过一些地址，这样它们就会被其他块阻塞。但它不会阻止。

RubyDNS.run_server(listen: INTERFACES, asynchronous: false) do
  upstream = RubyDNS::Resolver.new([[:udp, "8.8.8.8", 53], [:tcp, "8.8.8.8", 53]])

  match(/^([\d\.]+)\.in-addr\.arpa$/, IN::PTR) do |transaction, match_data|

    domain = nil # just for test

    if domain
      transaction.respond!(Name.create(domain))
    else
      # Pass the request to the otherwise handler
      # !!! this doesn't work
      false
    end
  end

  otherwise do |transaction|
    transaction.passthrough!(upstream)
  end
end

当我从匹配块返回false时 - 它不会以其他方式阻止。如何解决这个问题？

我发现如何继续阻止匹配阻止：使用＆＃39; next！＆＃39;

match(/^([\d\.]+)\.in-addr\.arpa$/, IN::PTR) do |transaction, match_data|

domain = nil # just for test

if domain
  transaction.respond!(Name.create(domain))
else
  # Pass the request to the otherwise handler
  next!
end
end
otherwise do |transaction|
   transaction.passthrough!(upstream)
end

RubyDNS否则无效
