Question

我当时从标题中刮取了这个site，并且还尝试了刮除标题之后的图像。原来是在抓取时返回了以下数据：

<div itemscope itemtype="https://schema.org/ItemList" class="group card-8-group-1 clearfix">
              <meta itemprop="itemListOrder" content="https://schema.org/ItemListOrderDescending" />
              <article  itemprop="itemListElement" itemscope itemtype="https://schema.org/Article" class="card card-1 news-card-1 card-type-article  type-article" data-sponsorship-type="card" data-sponsorship-article-id="1qo8sz0z1kaqb1dpj038v8658h" data-sponsorship-article-type="article" data-sponsorship-primary-tag="1pgecmpab62ei1akyb084izq3o" data-sponsorship-secondary-tag="22doj4sgsocqpxw45h607udje">
                 <a data-side="link" href="/en/news/spurs-investigation-aurier-appears-break-lockdown-protocols/1qo8sz0z1kaqb1dpj038v8658h" itemprop="url" data-sponsorship-slot="card" data-sponsorship-slot-id="front" class="type-article">
                    <div class="picture article-image" data-module="responsive-picture">
                       <img class="picture__image picture__image--lazyload" data-srcset="&amp;quality=60&amp;w=640 320w,&amp;quality=60&amp;w=560 480w,&amp;quality=60&amp;w=690 740w,&amp;quality=60&amp;w=800 980w,&amp;quality=60&amp;w=970 1580w" /> 
                       <noscript class="picture__polyfill"> <img src="https://images.daznservices.com/di/library/GOAL/5f/da/serge-aurier_191f5i34z69us1fausrs9k0mjk.jpg?t=1445827096&amp;quality=60&amp;h=170" alt="Serge Aurier" /> </noscript>
                    </div>
                    <div class="title">
                       <h3 title="Spurs launch investigation as Aurier appears to break lockdown protocols for a third time" itemprop="headline">Aurier appears to break lockdown protocols for a third time</h3>
                       <div class="image" data-sponsorship-slot="card" data-sponsorship-slot-id="image"></div>
                    </div>

它似乎页面正在使用延迟加载。我的问题是如何提取具有完整缩放的img？

Answer 1

要获取完整尺寸的图像，只需在图像URL中手动将w=55替换为w=970即可。

例如：

import requests
from bs4 import BeautifulSoup

url = 'https://www.goal.com/en/premier-league/2kwbbcootiqqgmrzs6o5inle5'

soup = BeautifulSoup(requests.get(url).content, 'html.parser')

for title, image in zip(soup.select('.card-type-article h3'),
                        soup.select('.card-type-article img')):
    title = title.get_text(strip=True)
    full_img_url = image['src'].replace('w=55', 'w=970')

    print('{:<70}{}'.format(title, full_img_url))
