如何在没有Rhosync或RhoConnect的情况下使用Rhodes? [英] How to use Rhodes without Rhosync or RhoConnect?

问题描述

我知道我们可以使用直接Web服务在不使用Rhosync或Rhoconnect的情况下使用Rhodes同步数据，但是我在这里有点困惑将代码放置在何处以及如何初始化它.有人可以帮我举个小例子吗?

I know we can sync data using rhodes without Rhosync or Rhoconnect by using direct web service, but I'm here little bit confuse where to place that code for webservice call and how do we initialize it. Can anyone help me with small example?

在此先感谢.

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
