get_response

require 'net/https'
response = Net::HTTP.get_response('http://www.sina.com.cn','index.html')
puts response.body

ruby抱错了：
c:/ruby/lib/ruby/1.8/net/http.rb:560:in `initialize': getaddrinfo: no address as
sociated with hostname. (SocketError)

不需要http://否则会出错的！

response = Net::HTTP.get_response('www.sina.com.cn','index.html')
这样就可以了。
