如何在rails的后端从algolia place API中获取国家简称？

# 在Gemfile中添加HTTParty库
gem 'httparty'

# 执行bundle install安装依赖

# 在Rails后端的控制器中实现获取国家简称的方法
class PlacesController < ApplicationController
  include HTTParty

  def get_country_abbreviation
    # 构建Algolia Place API的请求URL
    url = "https://places.algolia.com/v1/..."
    # 设置请求头，包括Algolia的API密钥
    headers = {
      "X-Algolia-API-Key" => "YOUR_ALGOLIA_API_KEY",
      "X-Algolia-Application-Id" => "YOUR_ALGOLIA_APP_ID"
    }
    # 发送HTTP GET请求到Algolia Place API
    response = self.class.get(url, headers: headers)
    # 解析返回的JSON结果
    result = JSON.parse(response.body)
    # 提取国家简称
    country_abbreviation = result["country"]["abbreviation"]
    # 返回国家简称作为响应
    render json: { country_abbreviation: country_abbreviation }
  end
end
