Answer 1

I got it and it works for me.
class ProductController < Rho::RhoController
include BrowserHelper
# GET /product
def index
response = Rho::AsyncHttp.get(:url => "example.com/products.json",
:headers => {"Content-Type" => "application/json"})
#result = response["body"]
render :back => '/app'
end
# GET /product/{1}
def show
id =#params['id']
response = Rho::AsyncHttp.get(:url => "example.com/products/"+ id +".json",
:headers => {"Content-Type" => "application/json"})
#result = response["body"]
end
# GET /product/new
def new
#product = product.new
render :action => :new, :back => url_for(:action => :index)
end
# GET /product/{1}/edit
def edit
id =#params['product_id'].to_s
response = Rho::AsyncHttp.get(:url => "example.com/products/#{id}.json",
:headers => {"Content-Type" => "application/json"})
#result = response["body"]
end
# POST /product/create
def create
name = #params['product']['name']
price = #params['product']['price']
body = '{"product" : {"name" : "'+ name +'","price" :"'+ price +'" } }'
#result = Rho::AsyncHttp.post(:url => "example.com/products.json",
:body => body, :http_command => "POST", :headers => {"Content-Type" => "application/json"})
redirect :action => :index
end
# POST /product/{1}/update
def update
name=#params['product']['name']
price=#params['product']['price']
body = '{"product" : {"name" : "' + name + '","price" :"' + price + '" } }'
id = #params["product_id"].to_s
response = Rho::AsyncHttp.post(:url => "example.com/products/#{id}.json",
:body => body, :http_command => "PUT",:headers => {"Content-Type" => "application/json"})
redirect :action => :index
end
# POST /product/{1}/delete
def delete
id = #params["product_id"].to_s
response = Rho::AsyncHttp.post(:url => "example.com/products/#{id}.json",
:http_command => "DELETE",
:headers => {"Content-Type" => "application/json"})
redirect :action => :index
end
end

Answer 2

Most easy form of http server request is next:
Rho::AsyncHttp.get(
:url => "http://www.example.com",
:callback => (url_for :action => :httpget_callback)
)
where httpget_callback is name of the controller callback method.
See more details at official Rhodes docs.
