我在我的Web应用程序中使用带有RestClient gem的Google Web Service API来查找具有特定字符串的企业。例如，传入'car dealership'应该返回我附近所有汽车经销商的结果。
目前，我可以得到第一页的结果。已经传入了next_page_token，但仍然无法得到相同的结果。我不知道我的代码哪里出错了。真的很感谢帮助！

SEARCH_ENDPOINT = 'https://maps.googleapis.com/maps/api/place/textsearch/json'.freeze
    DETAILS_ENDPOINT = 'https://maps.googleapis.com/maps/api/place/details/json'.freeze

    def initialize(query)
      @params = {
        query: query,
        fields: 'name,formatted_phone_number,formatted_address,website,place_id,types',
        key: API_KEY
      }
      @results = []
    end

    def extract
      loop do
        page_token = @results.last&.dig('next_page_token')

        page = fetch_page(page_token)
        break if page.nil?

        @results += page['results']

        break if page['next_page_token'].nil?

        # Add a delay to avoid OVER_QUERY_LIMIT errors (10 requests per second)
        sleep(10)
      end

      @results = @results.map do |result|
        result_details = fetch_place_details(result['place_id'])
        result.merge(result_details)
      end

      upsert_businesses(clean_data(@results))
    end

    private

    def fetch_page(page_token)
      response = RestClient.get(SEARCH_ENDPOINT, params: @params.merge({page_token: page_token}))

      return nil unless response.code == 200

      JSON.parse(response.body)
    end

    def fetch_place_details(place_id)
      response = RestClient.get(DETAILS_ENDPOINT, params: @params.merge({place_id: place_id}))

      return {} unless response.code == 200

      details = JSON.parse(response.body)['result']

      details || {}
    end

将下一页标记传递给参数，期望新的响应页。但得到同样的结果。
