python实现淘宝商品批量下载详情页图片

1.打开某件宝贝的详情页地址url

例如下图这款windows10鼠标垫宝贝，url地址为下图红色框框里！

注意：目前此代码不支持天猫详情页图片下载。可以关注我后续的文章，也可以自行研究，原来一样。只需用bs4库提取里面的图片地址即可！

2.在chrome浏览器查看自己的淘宝cookie值

打开chrome谷歌浏览器，按F11，选择红框的选项。复制红色框cookie的值

3.将url和cookie值替换到下面的代码中

废话不说，撸上代码

import re
import requests
import json
from PIL import Image
from io import BytesIO
from bs4 import BeautifulSoup
import os
import requests
import re
# 填入自己的cookie值
headers = {
'Cookie':'thw=cn; hng=CN%7Czh-CN%7CCNY%7C156; miid=183661675555435285645; tracknick=fang510515; x=e%3D1%26p%3D*%26s%3D0%26c%3D0%26f%3D0%26g%3D0%26t%3D0; cna=4sqnF8VfoEkCAXQXEWvoraFY; enc=sEsCaCgbG%2F7kOXEDpdvq%2Bj327K0mOB5VonNlrBkMgJkw4qAl6s%2FwfOjmXjo%2BTmwhSNGIv5A%2ByJc0sMuYvGrKLQ%3D%3D; t=cc2bbe7d83fd5b912599657b58845855; lgc=fang510515; cookie2=1d7792f371a1102sdffds5bdfce0599; _samesite_flag_=true; xlly_s=1; _m_h5_tk=f73a3b46fa69eeb62580bb4ecc79fad2_1617092244832; _m_h5_tk_enc=7e09360c3902979942a9bbc1fe929051; sgcookie=E100NOaY0%2FXDpKjXKEyIRdTwOhgIv6%2Bjd8EopuabwNQSkPfNNz7f%2BQU2wXBPsURcOxb36kPkQNL8tU0iniNsDjgLYw%3D%3D; unb=734830797; uc3=nk2=BdGi0ISfvR%2FaVg%3D%3D&lg2=U%2BGCWk%2F75gdr5Q%3D%3D&id2=VAKJAqbsk6Uh&vt3=F8dCuAtXiGqgXQCM45Q%3D; csg=64d10512; cookie17=VAKJAqbsk6Uh; dnk=fang510515; skt=5beef9053deb82cc; existShop=MTYxNzA4NDMzMw%3D%3D; uc4=id4=0%40VhvFlqHxePfviKXqsPggkrddrlo%3D&nk4=0%40B12%2BhJ%2Fdh7REbYJoaCvbYs281MFQ; publishItemObj=Ng%3D%3D; _cc_=Vq8l%2BKCLiw%3D%3D; _l_g_=Ug%3D%3D; sg=575; _nk_=fang510515; cookie1=U7Si1egRkbaxeC7%2Fe4EJGKbb9eDczzOuyawQwm8BZgY%3D; v=0; lLtC1_=1; mt=ci=14_1; _tb_token_=bpTggBixbw0F8; uc1=cookie14=UIHiLt3xD8xYTw%3D%3D&pas=0&cookie21=VFC%2FuZ9ajCbF8%2BYBpbBdiw%3D%3D&cookie16=Vq8l%2dfsasSLZMFWHxqs8fwqnEw%3D%3D&existShop=true&cookie12=Uoe1hdEVxsvQ1Q%3D%3D; tfstk=cNOfB-DHjoqfcIDagEgz_A5rKRfFZF4C5xsDlpONIXqbfgLfirFFAiHBIlFRpa1..; l=eBEyWHVRjzu6i_KLXOfwourza77OSIRAguPzaNbMiOCPOJC65q-RW6ZVZRYBC3GVh60wR3-2Y4KHBdfb4wsWRKe5DDwQHmn; isg=BJycLQZiEM2Xf-QS1pfG3WP4bbpOFUA_XbV3z3adqAdrwTxLniUQzxJzJSk5yXiX',
