可以使用requests库中的Session类来存储cookie，示例代码如下：

import requests
from bs4 import BeautifulSoup

session = requests.Session()
cookie = 'your_cookie_here'
session.headers.update({'cookie': cookie})

def get_with_cookie(url):
    try:
        resp = session.get(url)
        return resp.text
    except requests.exceptions.RequestException as e:
        print("请求异常:", e)
        return None

# 解析HTML内容，提取商品名称、价格和销量信息
def parse_html(html):
    try:
        soup = BeautifulSoup(html, 'html.parser')
        title = soup.select_one('h3.tb-main-title[data-title]')
        return title
    except Exception as e:
        print("解析异常:", e)
        return None

# 测试接口：
url = 'https://item.taobao.com/item.htm?id=699089474285&ali_refid=a3_430673_1006:1102522391:N:%2BAkz14GC%2BXi%2Bma9dw7y9M4p5Yhq5iT8I:f9e826228fbc823934848d20e28dff81&ali_trackid=162_f9e826228fbc823934848d20e28dff81&spm=a2e0b.20350158.31919782.5'
resp_text = get_with_cookie(url)
if resp_text is not None:
    title = parse_html(resp_text)
    if title is not None:
        # 打印商品信息
        print(title.text.strip())
    else:
        print("解析失败")
else:
    print("请求失败")

在这个示例代码中，我们使用了requests.Session()来创建一个session对象，并将cookie存储在session对象的headers中。在请求时，我们直接调用session.get()方法即可实现带cookie请求。这样，我们就可以不用在每次请求时都带上cookie了。
