python - 如何在python中从img html中抓取src

Question

我正在尝试抓取 img 的 src，但是我发现的代码返回了许多 img src，但不是我想要的。我不明白我做错了什么。我正在“https://www.tripadvisor.dk/Restaurant_Review-g189541-d15804886-Reviews-The_Pescatarian-Copenhagen_Zealand.html”上抓取 TripAdvisor

这是我试图从中提取的 HTML 片段:

 <div class="restaurants-detail-overview-cards-LocationOverviewCard__cardColumn--2ALwF"><h6>Placering og kontaktoplysninger</h6><span><div><span data-test-target="staticMapSnapshot" class=""><img class="restaurants-detail-overview-cards-LocationOverviewCard__mapImage--22-Al" src="https://trip-raster.citymaps.io/staticmap?scale=1&amp;zoom=15&amp;size=347x137&amp;language=da&amp;center=55.687988,12.596316&amp;markers=icon:http%3A%2F%2Fc1.tacdn.com%2F%2Fimg2%2Fmaps%2Ficons%2Fcomponent_map_pins_v1%2FR_Pin_Small.png|55.68799,12.596316"></span></div></span>

我希望代码返回:(来自 src 的子字符串)

55.68799,12.596316

我已经尝试过:

    import pandas as pd
    pd.options.display.max_colwidth = 200
    from urllib.request import urlopen
    from bs4 import BeautifulSoup as bs
    import re

    web_url = "https://www.tripadvisor.dk/Restaurant_Review-g189541-d15804886-Reviews-The_Pescatarian-Copenhagen_Zealand.html"
    url = urlopen(web_url)
    url_html = url.read()

    soup = bs(url_html, 'lxml')
    soup.find_all('img')

    for link in soup.find_all('img'):
        print(link.get('src'))

返回的内容与此类似，但不是我需要的 src :

您只需请求并重新即可完成此操作。它只是 src 的坐标部分，它是基于位置的变量。

import requests, re

p = re.compile(r'"coords":"(.*?)"')
r = requests.get('https://www.tripadvisor.dk/Restaurant_Review-g189541-d15804886-Reviews-The_Pescatarian-Copenhagen_Zealand.html')
coords = p.findall(r.text)[1]
src = f'https://trip-raster.citymaps.io/staticmap?scale=1&zoom=15&size=347x137&language=da&center={coords}&markers=icon:http://c1.tacdn.com//img2/maps/icons/component_map_pins_v1/R_Pin_Small.png|{coords}'
print(src)
print(coords)
