Rest-client get header only

ruby-talk
1

Hi, using the great rest-client from Adam Wiggins, but I can't seam to
be able work out how to get just the HEAD of a URL.
i.e. in curl I would : curl -I URL

I'm getting the data just fine with:
return_data = RestClient.get "URL"

Is there a way of doing this, or should I go about it a different way?

I'm using it to get the filename sent back from a send_data command in a
rails app.

Still very new to all this ruby/rails jive, but liking it so far!

Keith.

Hi Keith,

Hi, using the great rest-client from Adam Wiggins, but I can't seam to
be able work out how to get just the HEAD of a URL.

Looking at the documentation at http://rest-client.heroku.com/rdoc/ it
does not appear that there is a RestClient#head method. However,
looking at the internals you may be able to do:

uri = 'http://google.com'
headers = {}

RestClient::Request.execute(:method => :head,
  :url => url,
  :headers => headers)

I'm using it to get the filename sent back from a send_data command in a
rails app.

Still very new to all this ruby/rails jive, but liking it so far!

Welcome aboard!

The ruby standard library has net/http, with which you can do:

  require 'net/http'

  conn = Net::HTTP.start('www.whatever.com')
  conn.head('/').each_header do |k,v|
    puts "#{k} = #{v}"
  end

Thanks Michael, tried to use the :method => :head, but couldn't get it
to fly.
Sure there is a way of using that method if you know your way round ruby
better than I. Cheers for the suggestion.

Thanks Mark that cracked it!

Now able to get the filename, and the actual data, so I can save to
disk, rather than using a default name for the data as I was before.

Many thanks,

Keith.
