使用 BeautifulSoup 在 DIV 标签下刮取 IMG SRC

Question

我正在尝试获取位于 Div 标记下的图像的 src。我的代码给了我一个错误，KeyError: 'src'

这是我的代码：

for page in range(1,4):
# code that gets dynamic URL
url = sys.argv[1] + "{}".format(page)
print(url)
html=urlopen(url)
soup=BeautifulSoup(html,"lxml")

for article in soup.find_all('article',class_='o-hit'):
    div=soup.find('div',{"class":"o-rating_thumb@m-"})
    img_src = div.find('img').attrs['src']
    #img_src = article.find('div',class_ ='o-rating_thumb c-white').img['src']   
    headline = article.h2.text.strip()

    summary = article.find('p',class_ ='mt-15@m+ t-d5@m- t-d5@tp+ c-gray-3').text.strip()

    #img_src = "none"

    print(headline)
    print(summary)
    print(img_src)
    csv_writer.writerow([headline,summary,img_src])

网页在这里： EndGadget Blog page 10

Answer 1

对于每个页面上最顶部的新闻，您可以从'src'属性本身获取图像源。

您可以先使用find() 方法导航到包含图像的div。接下来在该 div 中，您可以找到 img 标记并从其 attributes 获取其来源。

import requests
from bs4 import BeautifulSoup
url='https://www.engadget.com/reviews/latest/page/10/'
res=requests.get(url)
soup=BeautifulSoup(res.text,'html.parser')
div=soup.find('div',{"class":"o-rating_thumb@m-"})
print(div.find('img').attrs['src'])

输出：

https://o.aolcdn.com/images/dims?resize=810%2C455&crop=810%2C455%2C0%2C0&quality=80&image_uri=https%3A%2F%2Fo.aolcdn.com%2Fimages%2Fdims%3Fcrop%3D1400%252C933%252C0%252C0%26quality%3D85%26format%3Djpg%26resize%3D1600%252C1066%26image_uri%3Dhttp%253A%252F%252Fo.aolcdn.com%252Fhss%252Fstorage%252Fmidas%252F85a4e2b124ba329ab520e80e306f07eb%252F206517051%252FIMG_5243e.jpg%26client%3Da1acac3e1b3290917d92%26signature%3Dcea6158d0bf02768d31ee67f2694be6cafaf200c&client=amp-blogside-v2&signature=08a97a1109f1c3287c6766fa284104c6f78770fe

编辑以抓取页面的所有新闻来源：

虽然第一张图片有src属性，但要抓取后续图片，我们必须使用data-originals属性（您可以查看页面来源并找出这一点）。我认为这就是您收到 AttributeError 的原因

我能够像这样抓取所有新闻条目

import requests
from bs4 import BeautifulSoup
url='https://www.engadget.com/reviews/latest/page/10/'
res=requests.get(url)
soup=BeautifulSoup(res.text,'html.parser')
articles=soup.find_all('article',{"class":"o-hit"})
for article in articles:
    print("Heading: ", article.find('h2').text.strip())#heading
    print("Summary: ", article.find('p').text.strip())#summary
    print("Image Source:", article.find('img').attrs['data-original'])#image src
    print()

输出：
