从'a'标签中查找href没有找到第一个'a'标签，我该如何解决？

Question

我是 python 新手，我确实在尝试刮。由于某种原因，每个职位发布都保存在“a”标签而不是 div 下，div 也包含 href。 这是项目输出：print(item)

<a class="tapItem fs-unmask result job_e0fb3e5f520856c0 resultWithShelf sponTapItem tapItem-noPadding desktop" data-hide-spinner="true" data-jk="e0fb3e5f520856c0" data-mobtk="1favs1gn0t5v1800" href="/company/Acentury/jobs/New-Graduate-Software-Developer-e0fb3e5f520856c0?fccid=5c6453896b020232&amp;vjs=3" id="job_e0fb3e5f520856c0" rel="nofollow" target="_blank"><div class="slider_container"><div class="slider_list"><div class="slider_item"><div class="job_seen_beacon"><table cellpadding="0" cellspacing="0" class="jobCard_mainContent" role="presentation"><tbody><tr><td class="resultContent"><div class="heading4 color-text-primary singleLineTitle tapItem-gutter"><h2 class="jobTitle jobTitle-color-purple jobTitle-newJob"><div class="new topLeft holisticNewBlue desktop"><span class="label">new</span></div><span title="New Graduate Software Developer">New Graduate Software Developer</span></h2></div><div class="heading6 company_location tapItem-gutter"><pre><span class="companyName">Acentury</span><div class="companyLocation">Richmond Hill, ON<span class="remote-bullet">•</span><span>Temporarily Remote</span></div></pre></div><div class="heading6 tapItem-gutter metadataContainer"><div class="metadata salary-snippet-container"><span class="salary-snippet">$44,182 - $126,699 a year</span></div></div><div class="heading6 error-text tapItem-gutter"></div></td></tr></tbody></table><table class="jobCardShelfContainer" role="presentation"><tbody><tr class="jobCardShelf"><td class="shelfItem indeedApply"><span class="iaIcon"></span><span class="ialbl iaTextBlack">Easily apply</span></td></tr><tr class="underShelfFooter"><td><div class="heading6 tapItem-gutter result-footer"><div class="job-snippet"><ul style="list-style-type:circle;margin-top: 0px;margin-bottom: 0px;padding-left:20px;">

我的代码是

divs = soup.find_all('a', class_ = 'tapItem')
for item in divs:
   for people in item.find_all('a'):
       print(people)   
       for ok in people.find_all('a', class_ = 'tapItem'):
           linkJob1 = ok.get('href')
   print(linkJob1)

人物不包含第一个'a'标签，而是其他标签，我该如何解决这个问题？谢谢

预期结果是每个职位/卡片的href

如果您在类result 的元素级别循环，您只需要一个ID（作业ID），您可以从data-jk 属性中提取它。然后，您可以像网站一样，动态构建 url：

import requests
from bs4 import BeautifulSoup as bs

r = requests.get('https://ca.indeed.com/jobs?q=software+developer&l=Toronto,+ON&start=0')
soup = bs(r.content, 'lxml')

for job in soup.select('.result'):
    print(job.select_one('.jobTitle').get_text(' '))
    print(f'https://ca.indeed.com/viewjob?jk={job["data-jk"]}')
