ruby多线程下载示例

#多线程批量下载http://www.milw0rm.com/上的exploits，自动存放。下图片、恶意投票都可^^^^^

require "open-uri"
if $*[0]==nil or $*[1]==nil or $*[2]==nil
abort "用法示例：ruby #$0 开始数　结束数　存放的目录 EX:如ruby #$0 200 300 c:\\1 "
end
time1 = Time.now
threads = []
for i in $*[0]..$*[1]
   exploits= "http://www.milw0rm.com/exploits/"+i.to_s
   threads << Thread.new(i) do |thei|
     begin
     data=open(exploits){|f|f.read}
     open("#{$*[2]}\\#{thei}.htm","wb"){|f|f.write(data)}
     print thei,"-"
     rescue
      #...如果没有这个url，显示404不去管它,让它没有错误回显
    end
end
end
threads.each {|thr| thr.join}
puts " 下载完成，共耗时：#{Time.now - time1}秒"
