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 def raw_data_put
require 'net/http'
begin
retailerRegistry=Hash.new()
retailerRegistry["RetailerId"]=12160
retailerRegistry["RetailerRegistryCode"]="cjq2I5Wc3u_zIU_QFkvy0w"
retailerRegistry["RegistrantFirstName"]="Kelly"
