Show headers and body text of an HTTP request in Ruby

Question

I'm sure this is easy, but I've searched pretty extensively and been unable to find an answer. I'm using the Net::Http library in Ruby and am trying to figure out how I show the complete body of an HTTP GET request? Something like the following:

GET /really_long_path/index.html?q=foo&s=bar HTTP\1.1
Cookie: some_cookie;
Host: remote_host.example.com

I am looking for the raw REQUEST , not the RESPONSE to be captured.

The #to_hash method of a request object may be useful. Here's an example to build a GET request and inspect headers:

require 'net/http'
require 'uri'

uri = URI('http://example.com/cached_response')
req = Net::HTTP::Get.new(uri.request_uri)

req['X-Crazy-Header'] = "This is crazy"

puts req.to_hash # hash of request headers
# => {"accept"=>["*/*"], "user-agent"=>["Ruby"], "x-crazy-header"=>["This is crazy"]}

And an example for a POST request to set form data and inspect headers and body:

require 'net/http'
require 'uri'

uri = URI('http://www.example.com/todo.cgi')
req = Net::HTTP::Post.new(uri.path)

req.set_form_data('from' => '2005-01-01', 'to' => '2005-03-31')

puts req.to_hash # hash of request headers
# => {"accept"=>["*/*"], "user-agent"=>["Ruby"], "content-type"=>["application/x-www-form-urlencoded"]}

puts req.body # string of request body
# => from=2005-01-01&to=2005-03-31
