Ruby Http gem (http client) inside Sinatra POST

I am trying to relay a GET request so when the user does a POST request to the server then the server does another GET request to some other URL and returns the result.

The issue is that when I use puts to print the result I see the correct result that I am expecting but the last line (I believe in ruby the last line of the function automatically returns) does not respond to the POST request (it returns empty response). Coming from JavaScript I believe it is doing an asynchronous GET call and POST response is not waiting until GET client is finished.

Any help would be appreciated.

require 'rubygems'
require 'sinatra'
require "http"

my_app_root = File.expand_path( File.dirname(__FILE__) + '/..' )

set :port, 80
set :bind, '0.0.0.0'
set :public_dir,   my_app_root + '/public'


post "/weather" do
  puts HTTP.get('https://www.metaweather.com/api/location/search/?query=milwaukee')  # prints correct result
  HTTP.get('https://www.metaweather.com/api/location/search/?query=milwaukee')       # response of POST method is empty string!
end

Changes to 

post "/weather" do
  puts HTTP.get('https://www.metaweather.com/api/location/search/?query=milwaukee')  # prints correct result
  HTTP.get('https://www.metaweather.com/api/location/search/?query=milwaukee').to_s
end

The HTTP.get method returns a HTTP::Response object rather than a String object.

From the source code only specific types of object can be returned.

 res = [res] if Integer === res or String === res
  if Array === res and Integer === res.first
    res = res.dup
    status(res.shift)
    body(res.pop)
    headers(*res)
  elsif res.respond_to? :each
    body res
  end
  nil # avoid double setting the same response tuple twice
