Question

def post_test
  require 'net/http'
  require 'json'
  @host = '23.23.xxx.xx'
  @port = '8080'
  @path = "/restxxx/abc/xyz"

  request = Net::HTTP::Get.new(@path, initheader = {'Content-Type' =>'application/json'})
  response = Net::HTTP.new(@host, @port).start {|http| http.request(request) }

  puts "Response #{response.code} #{response.message}: #{response.body}"
end

Use instance method Net::HTTP#get to modify the header of a GET request.

require 'net/http'

url = URI.parse('http://www.xyxx/abc/pqr')
http = Net::HTTP.new url.host
resp = http.get("#{url.path}?#{url.query.to_s}", {'Content-Type' => 'application/json'})
data = resp.body
puts data

@oecprashant Sorry, that's hash syntax error when typing code. I've updated the answer. – Arie Xiao Apr 15 '13 at 07:11

You can simply do this:

uri = URI.parse('http://www.xyxx/abc/pqr')
req = Net::HTTP::Get.new(uri.path, 'Content-Type' => 'application/json')

res = Net::HTTP.new(uri.host, uri.port).request(req)
