從特定電子商務網站的鏈接中抓取圖像

Question

我正在抓取一個電子商務網站以獲取經驗。 我目前在抓取產品圖像時遇到問題。 我已經抓取了產品所有現有圖像的 html 代碼，但無法從該 html 代碼中提取鏈接。

我試過的代碼是：

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')

我得到的輸出是這樣的：

<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>]

我想要的輸出：

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"

注意我試過： print(images['src'])它導致異常打印---

提前感謝您的幫助。

Answer 1

要從鏈接中獲取圖像 URL，您可以使用以下示例：

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'])

印刷：

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

編輯：要將產品保存到 csv，您可以執行以下操作：

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)

印刷：

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

[1 rows x 5 columns]

並保存data.csv

您的images變量是我所看到的 HTML <div>元素數組。 您應該遍歷數組中的每個項目，找到<img> ，然后獲取其src標簽，例如：

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