Question

我知道我们可以使用直接网络服务在没有Rhosync或Rhoconnect的情况下使用rhodes同步数据，但我在这里有点混淆将代码放在webservice调用的位置，以及我们如何初始化它。任何人都可以用小例子帮助我吗？

先谢谢。

Answer 1

我明白了它对我有用。

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

下一个最简单的http服务器请求形式：

Rho::AsyncHttp.get(
  :url => "http://www.example.com",
  :callback => (url_for :action => :httpget_callback)
)

其中httpget_callback是控制器回调方法的名称。
