python京东手机爬虫

代码如下：
import parsel as parsel
import requests
import csv  # 内置模块
from lxml import etree

def get_html(page):
    url = 'https://search.'
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36 SLBrowser/8.0.0.9231 SLBChan/30'
    }
    response = requests.get(url=url, headers=headers)
    # print(response.text)
    html = parsel.Selector(response.text)
    # print(html)
    return html

def parse_data(selector):
    href = selector.css('li::attr(data-sku) ')
    # href = selector.css('.p-img a::attr(href)').getall()
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131 Safari/537.36 SLBrowser/8.0.0.9231 SLBChan/30'
    }
    res = []
    for index in zip(href):
        # https://item.
        index_url = 'https://item.'+str(index[0])+'.html'
        response_1 = requests.get(url=index_url, headers=headers)
        selector_1 = parsel.Selector(response_1.text)
        print(selector_1)
        price = selector_1.css('ul.parameter2.p-parameter-list li:nth-child(1)::text').get()
        # #detail > div.tab-con > div:nth-child(1) > div.p-parameter > ul.parameter2.p-parameter-list > li:nth-child(1)
        print(price)

if __name__=='__main__':
    page = 1
    html = get_html(page)
    res = parse_data(html)

求教：按照我的方法爬取<li>标签下title的值，该怎么写？或者是不是我根本没有爬取到这个页面的html?
京东的价格和评论怎么爬取不到啊？
