代码如下，经过测试
require 'rubygems'
require 'eventmachine'
require 'em-http'
require 'pp'
$stdout.sync = true
class KeyboardHandler < EM::Connection
include EM::Protocols::LineText2
def post_init
print "> "
end
def receive_line(line)
line.chomp!
line.gsub!(/^\s+/, '')
case(line)
when /^get (.*)$/ then
site = $1.chomp
sites = site.split(',')
multi = EM::MultiRequest.new
sites.each do |s|
multi.add(EM::HttpRequest.new(s).get)
end
multi.callback {
puts ""
multi.responses[:succeeded].each do |h|
pp h.response_header.status
pp h.response_header
end
multi.responses[:failed].each do |h|
puts "#{h.inspect} failed"
end
print "> "
}
print "> "
when /^exit$/ then
EM.stop
when /^help$/ then
puts 'get URL[,URL]* gets a URL'
puts "exit - exits the app"
puts "help - this help"
print "> "
end
end
end
EM::run {
EM.open_keyboard(KeyboardHandler)
}
puts "Finished"

EventMachine Screencast — EM-HTTP-Request
