如何在Rails中执行Get/Post/Put请求

require 'open-uri'
require 'json'
require 'net/http'
class CoupleController < ApplicationController
  skip_before_filter :verify_authenticity_token, :only => [:raw_data_put]

  def raw_date_get
    #如果有GET请求参数直接写在URI地址中
    begin
      uri = 'http://qa.services.theknot.com/registry/v1/couples/2170045'
      html_response = nil
      open(uri) do |http|
        html_response = http.read
      end
      data = JSON.parse(html_response)
      registries=data["CoupleRegistries"]
      render json: data.has_key?("Id")
    rescue (excetpion)
      render json: excetpion
    end
  end
