Python 请求将图像 src 作为相对路径而不是绝对路径

Question

在下图中，我将图像的链接作为 src。

但是当使用 BeautifulSoup 时，我得到了这个输出：

image['src']
assets/images/content/TUL_5890.jpg

你能告诉我在这种情况下如何提取图像链接吗？ 我认为这是因为代码中的onerror 。 但我不知道如何解决它。

Answer 1

如果您在soup中看到响应 html，

<a class="img-wrapper fancybox" data-caption="Pedestrian Crosswalk Sign" data-fancybox="group" href="assets/images/content/street_view_1a.jpg">
<img alt="Pedestrian Crosswalk Sign" src="assets/images/content/street_view_1a.jpg"/>

它没有您在 chrome 中看到的完整路径，这可能是您的浏览器添加的。 因此，您没有获得完整的路径。 您必须提取标签 src 并将其与 FQDN 连接。

from bs4 import BeautifulSoup
import requests
response = requests.get('https://www.pexco.com/traffic/products/pedestrian-safety-products/in-street-pedestrian-crosswalk-signs/')

soup = BeautifulSoup(response.text, 'lxml')
for imgTag in soup.find_all('img'):
    img_src = imgTag['src']
    if ('assets' in img_src):
        print('https://www.pexco.com/' + img_src)
    else:
        print(img_src)
