Downloading a file using ruby

ruby-talk
1

Hi All,
       I want to download a file from my web application using/calling
ruby code.
Manually i can download reports by clicking on 'DOWNLOAD' button in my
app, which in turn gets the file from servlet path(where the files are
stored).
My question is, how can i automate this download part in ruby, if its
feasible.
    During my googling, i found a set of ruby code to download pictures
from a site.

snippet of the code looks like this:
<CODE>
require 'net/http'

Net::HTTP.start("static.test.com") { |http|
  resp = http.get("/92/2134322cedc5fef7_o.jpg")
  open("fun.jpg", "wb") { |file|
    file.write(resp.body)
   }
}
<CODE>

       Please let me know if i could use similar technique to download a
file(excel file).

Thanks

      I

require 'open-uri'

  open("http://localhost/jtprince/TRASH.TRASH") do |io|
    data = io.read
  end

Are you looking for something like that? This works on my own machine
to grab files under the web server.

yes, this should download any kind of file (including excel). I use
it to read/write mp3 files from online:

require 'open-uri'
open("http://someplace.com/somefile.mp3") do |in_io|
  File.open("somefile.mp3", 'w') do |out_io|
    out_io.print in_io.read
  end
end

Thanks guys for the reply.
   Actually i had mistaken that the download picks the file from web
server, but after talking to my developers i realized that they are
internally getting the file using ftp.
   I wanted to know how can i "pull a file from ftp". Is there any ruby
library to pull or push files through "ftp"

Cheers
