Python爬虫requests.get方法无法显示div中折叠内容

问题遇到的现象和发生背景

如题，我希望获得完整的request返回并爬取某div标签内内容，然而我通过beautifulsoup发现该部分的div内容被省略掉了

    dom = etree.HTML(res)

    for list_num in range(2, 10):

        # result.append(dom.xpath('//*[@id="app"]/div/div[2]/div[1]/div[1]/div[2]/div[1]/div[2]/div[2]/p[1]/span[1]/text()'.format(list_num)))
        # result.append(dom.xpath('/html/body/div[1]/div/div[2]/div[1]/div[1]/div[2]/div[1]/div[{}]/div[2]/p[2]/span[1]'.format(list_num)))
        # result.append(dom.xpath('/html/body/div[1]/div/div[2]/div[1]/div[1]/div[2]/div[1]/div[{}]/div[2]/p[2]/span[2]/span'.format(list_num)))
        # result.append(dom.xpath('/html/body/div[1]/div/div[2]/div[1]/div[1]/div[2]/div[1]/div[{}]/div[2]/p[2]/span[3]/text()'.format(list_num)))
        soup = BeautifulSoup(res)
        print(soup.prettify())
        print(soup.select('div'))

        print(result)

我的解答思路和尝试过的方法

尝试过在get方法中添加header和cookie，无果，问题并非在于无法返回而在于返回结果不全。希望这个问题能够被解决。

该页面数据是动态加载的，需要用此链接用post请求去获取
https://www.xuetangx.com/api/v1/lms/get_product_list/?page=1

不要查看元素，用查看源文件的方式，查看你想要的数据是否存在于html文件中

一般来说，很多页面的数据都是通过xhr进行获取的，仅仅只进行页面的 requests.get 是无法获取xhr的
