从特定电子商务网站的链接中抓取图像

如何解决从特定电子商务网站的链接中抓取图像

我正在抓捕一个电子商务网站以获取经验。我目前在抓取产品图片时遇到问题。我已经为商品的所有当前图像抓取了HTML代码，但是无法从该HTML代码中提取链接。

我尝试的代码是：

import requests
from bs4 import BeautifulSoup
import pandas as pd
baseurl='https://www.preispirat24.com/neu-im-september/'
baseforimages='https://www.preispirat24.com/'
headers={
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML,like Gecko) Chrome/74.0.3729.169 Safari/537.36'
   
}   

productlinks=[]
for x in range(0,1,1):    
    r=requests.get('https://www.preispirat24.com/neu-im-september/?page={}'.format(x))
    soup=BeautifulSoup(r.content,'html.parser')

    productlist=soup.find_all('div',class_='title-description')
    item='title-description'

    for item in productlist:
        for link in item.find_all('a',href=True):
            productlinks.append(link['href'])
            a=(link['href'])
            
            

#testlink='https://www.preispirat24.com/Lufterfrischer/axe-air-fresher/axe-mini-vent-dark-temptation-air-freshener-lufterfrischer-6er-t-dsp.html'
insultlist=[]
images=[]
for link in productlinks:
    b=link
    try:
        r=requests.get(link,headers=headers)
        soup=BeautifulSoup(r.content,'html.parser')
        title=soup.find('h1',class_="product-info-title-desktop hidden-xs hidden-sm").text.strip()
        description=soup.find(class_='tab-body active',itemprop="description").text.strip()
        itemnumber=soup.find('span',itemprop="model").text.strip()

        images=soup.find_all(class_='align-vertical')
        print(images)
        #print (images['src'])
    except:
        print('----')
    insult={
        'title':title,'description':description,'itemnumber':itemnumber,'images':images,'productlink':b
    }
   
    insultlist.append(insult)
df=pd.DataFrame(insultlist)
print('Saving :',title)
print(df.head)
df.to_csv('3veerapreispirat24.csv')

我得到的输出类似于：

<img alt="Mobile Preview: 99671" data-magnifier-src="images/product_images/original_images/99671(1).jpg" src="images/product_images/gallery_images/99671(1).jpg" title="Mobile Preview: 99671"/>
</div>,<div class="align-vertical">
<img alt="Mobile Preview: 99671" data-magnifier-src="images/product_images/original_images/99671.jpg" src="images/product_images/gallery_images/99671.jpg" title="Mobile Preview: 99671"/>
</div>]

我想要的输出

images/product_images/original_images/99671(1).jpg
images/product_images/gallery_images/99671(1).jpg
images/product_images/original_images/99671.jpg
images/product_images/gallery_images/99671.jpg"

请注意，我已经尝试过：print(images['src']) 它导致异常打印---

示例产品链接来自要提取的产品图片

Link Here

预先感谢您的帮助。

解决方法

要从链接获取图像URL，可以使用以下示例：

import requests
from bs4 import BeautifulSoup


url = 'https://www.preispirat24.com/Verbrauchsartikel/Hygiene-Artikel-127/mund-nasen-maske-3-lagig-pink-mit-nasenbuegel-ohrschlaufen-einheitsgroesse-10-stuec.html'
soup = BeautifulSoup(requests.get(url).content,'html.parser')

for img in soup.select('#product_thumbnail_swiper [data-magnifier-src]'):
    print('https://www.preispirat24.com/' + img['data-magnifier-src'])

打印：

https://www.preispirat24.com/images/product_images/original_images/99649mix.jpg
https://www.preispirat24.com/images/product_images/original_images/99649.jpg
https://www.preispirat24.com/images/product_images/original_images/99649_0.jpg
https://www.preispirat24.com/images/product_images/original_images/99649_1.jpg

编辑：要将产品保存到csv，您可以执行以下操作：

import requests
import pandas as pd
from bs4 import BeautifulSoup


url = 'https://www.preispirat24.com/Verbrauchsartikel/Hygiene-Artikel-127/mund-nasen-maske-3-lagig-pink-mit-nasenbuegel-ohrschlaufen-einheitsgroesse-10-stuec.html'
soup = BeautifulSoup(requests.get(url).content,'html.parser')


title=soup.find('h1',class_="product-info-title-desktop hidden-xs hidden-sm").text.strip()
description=soup.find(class_='tab-body active',itemprop="description").text.strip()
itemnumber=soup.find('span',itemprop="model").text.strip()

images = []
for img in soup.select('#product_thumbnail_swiper [data-magnifier-src]'):
    images.append('https://www.preispirat24.com/' + img['data-magnifier-src'])
    # print('https://www.preispirat24.com/' + img['data-magnifier-src'])

df = pd.DataFrame({
        'title':title,'description':description,'itemnumber':itemnumber,'images':[images],'productlink':url
    })

df.to_csv('data.csv')
print(df)

打印：

                                               title  ...                                        productlink
0  Mund Nasen Maske 3-lagig PINK mit Nasenbügel,...  ...  https://www.preispirat24.com/Verbrauchsartikel...

[1 rows x 5 columns]

并保存data.csv

您看到的images变量是HTML <div>元素的数组。您应该遍历数组中的每个项目，找到<img>，然后获取其src标签，例如：

for element in images:
    url = element.find("img").get("src")
