Render JSON in Rails

Question

I want to see the following code in json format. When I do so I get a blank page with no content. In the rubymine debugger I have the correct information in json format.

include Java

require 'net/http'

class PatientRecordController < ApplicationController

  def index
    url = 'http://localhost:8080/patient/record/v2/'
    data_raw = Net::HTTP.get_response(URI.parse(url)).body

    @data_json = ActiveSupport::JSON.decode(data_raw)

    respond_to do |format|
      format.json {render json: @data_json}
    end

  end
end

Answer 1

您必须在输入浏览器的路径末尾添加.json 。

Answer 2

What is the path to this particular index action? This code should indeed render JSON, which your debugger is indicating that it indeed is.

The URL you should be visiting is something akin to http://your_host/patient_records/index.json .

Answer 3

如果你不想改变包含render json: @data_json的请求，你可以放弃respond_to块render json: @data_json本身就可以了。
