我有这个http://localhost:3000/api/products请求，它返回带有产品对象列表的 json 格式输出。我听说在某些情况下最好使用 multi-gets 设计，您可以像这样在 URI 中列出产品 ID http://localhost:3000/api/products?ids=1,2,3,4。我的问题是如何配置路由以返回这样的 URI？下面是返回的json输出http://localhost:3000/api/products。提前谢谢

控制器

def index
@products=Product.all

respond_to do |format|
  format.json { render json: @products.to_json}
  format.xml
end
end

json输出
[

    "category_id": null,
    "created_at": "2011-03-25T13:35:16Z",

有一个已停产的 gem，它是为 sproutcore（现为 ember）编写的，开箱即用：https ://github.com/drogus/bulk_api

但实际上，它根本不必那么难。对于单个控制器，我只会做类似的事情

 def index
   ids = params[:ids]
   if ids.blank?
     @categories = Category.all
   else  
     wanted_ids = ids.split(',')
     @categories = Categoriy.where(:id => wanted_ids)
   end
   render :json => @categories
 end

这有帮助吗？
