Question

我想仅使用浏览器测试来自Rails控制器GET操作的JSON响应。

Answer 1

一旦你弄清楚如何去做，这很简单。

您可以通过将类型添加为操作的扩展名来指定响应的类型。

例如，如果我们想要json响应，可以将请求更改为http://localhost:3000/models/action.json。

Answer 2

您必须在控制器中定义响应格式：

def action 
   @objects = Model.all
   respond_to do |format|
      format.html
      format.json
   end
end

或作为shorcut

def action 
   @objects = Model.all
   respond_to :html, :json
end

OR处理控制器级别的格式

class ModelsController < ApplicationController
   respond_to :html, :json

   def action
     @objects = Model.all
     respond_with(@objects)
  end
end

现在，当您呼叫http://localhost:3000/models/action.json时，响应将为JSON格式
