Hej,

stworzylem prosty server w ruby uzywajac webricka. Potrzebuje za jaego pomoca wyswietlac na stronie zawartosc polecen ‘netstat’

[code]require ‘webrick’
require ‘cgi’

class Netstat

def self.open
netstat_3489 = IO.popen(“netstat -an | grep 3489”)
netstat_3589 = IO.popen(“netstat -an | grep 3589”)
netstat_3689 = IO.popen(“netstat -an | grep 3689”)
netstat_3789 = IO.popen(“netstat -an | grep 3789”
if result_1 = netstat_3489.gets && result_2 = netstat_3589.gets && result_3 = netstat_3689.gets && result_4 = netstat_3789.gets
return result_1, result_2, result_3, result_4
elsif result_1 = netstat_3489.gets
return result_1, “PORTS 3589, 3689 and 3789 are FREE”
elsif result_2 = netstat_3589.gets
return result_2, “PORTS 3489, 3689, 3789 are FREE”
elsif result_3 = netstat_3689.gets
return result_3, “PORTS 3489, 3589, 3789 are FREE”
elsif result_4 = netstat_3789.gets
return result_4, “PORTS 3489, 3589, 3689 are FREE”
elsif result_1 = netstat_3489.gets && result_2 = netstat_3589.gets
return result_1, result_2, “PORTS 3689, 3789 are FREE”
elsif result_1 = netstat_3489.gets && result_3 = netstat_3689.gets
return result_1, result_3, “PORTS 3589, 3789 are FREE”
elsif result_1 = netstat_3489.gets && result_4 = netstat_3789.gets
return result_1, result_4, “PORTS 3589, 3689 are FREE”
elsif result_2 = netstat_3589.gets && result_3 = netstat_3689.gets
return result_2, result_3, “PORTS 3489, 3789 are FREE”
elsif result_2 = netstat_3589.gets && result_4 = netstat_3789.gets
return result_2, result_4, “PORTS 3489, 3689 are FREE”
elsif result_3 = netstat_3689.gets && result_4 = netstat_3789.gets
return result_3, result_4, “PORTS 3489, 3589 are FREE”
elsif result_1 = netstat_3489.gets && result_2 = netstat_3589.gets && result_3 = netstat_3689.gets
return result_1, result_2, result_3, “PORT 3789 is FREE”
elsif result_1 = netstat_3489.gets && result_2 = netstat_3589.gets && result_4 = netstat_3789.gets
return result_1, result_2, result_4, “PORT 3689 is FREE”
elsif result_2 = netstat_3589.gets && result_3 = netstat_3689.gets && result_4 = netstat_3789.gets
return result_2, result_3, result_4, “PORT 3489 is FREE”
elsif result_1 = netstat_3489.gets && result_3 = netstat_3689.gets && result_4 = netstat_3789.gets
return result_1, result_3, result_4, “PORT 3589 is FREE”
else
return “PORTS 3489, 3589, 3689, 3789 are FREE”
end
end

def self.print_results
result = Netstat.open
print result
end

end

class RunScript < WEBrick::HTTPServlet::AbstractServlet
def do_GET(req, res)
res[‘Content-Type’] = ‘text/html’
res.body = “#{Netstat.print_results}”
end
end

server = WEBrick::HTTPServer.new(:Port => 4000)
server.mount("/run", RunScript)

trap(“INT”){ server.shutdown }
server.start[/code]
Po odswiezaniu strony zawartosc tych polecen jest wyswietlana w terminalu, jak wyswietlac ta zawartosc w przegladarce?

zmiast

res.body = "<html>#{Netstat.print_results}</html>"

wpisz

res.body = "<html>#{Netstat.open}</html>"

Ale metoda “open” to największa patologia kodu jaką w życi widziałem.

Dzieki, wiem ze metoda open jest nie najciekawsza, wlasnie ja przerabiam :slight_smile:
