问题是图像是动态加载的;检查页面，并感谢 BeautifulSoupdocumentation，我能够刮所有需要的图像，给定一个产品。

获取给定链接的页面

我有一个存储数据的类，所以我将页面信息保存在示例中...

import urllib
from bs4 import BeautifulSoup

def take_page(self, url_page):
    req = urllib.request.Request(
        url_page,
        data=None
    )
    f = urllib.request.urlopen(req)
    page = f.read().decode('utf-8')
    self.page = page

抓取图像

下面的简单方法将返回第一个最小的图像

import json

def take_image(self):
    soup = BeautifulSoup(self.page, 'html.parser')
    img_div = soup.find(id="imgTagWrapperId")

    imgs_str = img_div.img.get('data-a-dynamic-image')  # a string in Json format

    # convert to a dictionary
    imgs_dict = json.loads(imgs_str)
    #each key in the dictionary is a link of an image, and the value shows the size (print all the dictionay to inspect)
    num_element = 0 
    first_link = list(imgs_dict.keys())[num_element]
    return first_link

因此，您可以根据需要应用这些方法，我认为这就是您改进代码所需的全部内容。

查看页面上“所有"img的代码示例

for asin in asins:
    site = 'https://www.amazon.it/'
    start = 'dp/'
    end = '/'
    url = site + start + asin + end
    print(url)
    resp1 = requests.get(url).content

    soup = BeautifulSoup(resp1, "html.parser")
    for i in soup.find_all("img"):
        print(i)

正确的方法是通过Amazon Affiliate API帐户，但如果你没有帐户的话。下面是使用ScraperAPI lxml的最新代码cssselect和PIL
关键部分是dom.cssselect从页面上的元素中获取图像，一个请求代理和使用PIL正确保存图像。在书籍上测试，其他页面将使用更高级别的元素

def save_img(url, name):
    response = requests.get(PROXY + url, stream=True)
    out_path = f'static/bookimg/{name}.jpg'
    try:
        i = Image.open(BytesIO(response.content))
        i.save(out_path)
    except (UnidentifiedImageError, OSError) as e:
        print(e)

def get_img_by_asin(asin, save_name):
    url = PROXY + f'https://www.amazon.co.uk/dp/{asin}/'
    print(url)
    html = requests.get(url).content
    dom = fromstring(html)
    try:
        img = dom.cssselect("#ebooks-img-canvas img")[-1]
        save_img(img.get('src'), save_name)
    except IndexError:
        print('No image or bad response')
