循环浏览页面总是得到相同的结果

Question

我正在尝试循环浏览页面并保存特定图像

import urllib.request
from bs4 import BeautifulSoup as bs

frontstring = 'http://www.haz.de/'

for i in range(1, 50):
    url = 'http://www.haz.de/Hannover/Aus-der-Region/Lehrte/Fotostrecken/' \
        + 'Digitales-Daumenkino-So-waechst-das-Parkhaus#p' + str(i)

    with urllib.request.urlopen(url) as page:
        soup = bs(page)
        galleryimage = soup.findAll('img', {'class': 'pda-fullgallery-large photo'})

        for imgtag in galleryimage:
            try:
                imgurl = frontstring + imgtag['src']
                imgname = 'img/fullgallery-large' + str(i) + '.jpg'
                urllib.request.urlretrieve(imgurl, imgname)
                print('saving image from ' + imgurl + ' to ' + imgname)
            except Exception as e:
                raise
            else:
                pass

然而图像总是一样的。我不知道哪里出了问题。如果我在浏览器中打开 url，它是正确的页面和图像，但汤似乎总是相同的代码。可能是一些非常愚蠢和简单的东西，但在尝试了很长时间才发现错误后我没有看到它。

那些才是真正的url，你看到的url是由JavaScript生成的。在抓取任何网站之前，您应该禁用 JavaScrip
