在beautifulsoup 上带有请求标头的剪贴画

Question

我有废图像的代码：

import requests, base64
from bs4 import BeautifulSoup


baseurl = "https://www.google.com/search?q=cat&sxsrf=APq-WBuyx07rsOeGlVQpTsxLt262WbhlfA:1650636332756&source=lnms&tbm=shop&sa=X&ved=2ahUKEwjQr5HC66f3AhXxxzgGHejKC9sQ_AUoAXoECAIQAw&biw=1920&bih=937&dpr=1"
headers = {"User-Agent" : "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:99.0) Gecko/20100101 Firefox/99.0"}

r_images = requests.get(url=baseurl, headers=headers)


soup_for_image = BeautifulSoup(r_images.text, 'html.parser') 
#find product images
productimages = [] 
product_images = soup_for_image.findAll('img')
for item in product_images:
    # print(item['src'])
    if "data:image/svg+xml" not in item['src']:
        productimages.append(item.get('src'))
print(productimages)

如果没有标头也可以，但是如果我使用请求标头，结果将是base64图像。那么有什么方法可以让我用请求标头废弃图像？

您可以添加 cookie 同意，它可以工作。
也许一些选择器将来会改变。

import requests, base64
from bs4 import BeautifulSoup

baseurl = "https://www.google.com/search?q=cat&sxsrf=APq-WBuyx07rsOeGlVQpTsxLt262WbhlfA:1650636332756&source=lnms&tbm=shop&sa=X&ved=2ahUKEwjQr5HC66f3AhXxxzgGHejKC9sQ_AUoAXoECAIQAw&biw=1920&bih=937&dpr=1"
headers = {"cookie": "CONSENT=YES+cb.20230531-04-p0.en+FX+908"}
result = requests.get(url=baseurl, headers=headers)
soup = BeautifulSoup(result.text, 'html.parser')
allProducts = soup.findAll(class_="u30d4")
number = 0
for product in allProducts:
    name = product.find(class_="rgHvZc")
    if name is not None:
        number += 1
        print("Product number %d:" % number)
        print("Name : " + name.text)
        productLink = product.find('a')
        print("Link: " + productLink["href"][7:])
        img = product.find('img')
        print("Image: " + img["src"])
        price = product.find(class_="HRLxBb")
        print("Price " + price.text)

希望我能帮到你。
