如何使用 python 网络抓取从职位发布中提取多个职位 url

Question

到目前为止，我已经创建了以下代码来提取所有信息，但我不知道如何提取 link。我试过使用 for 循环，但我得到了不同的 links。我真的希望有人能给我指出正确的方向。

def extract(page, tag):
    
url = f"https://www.jobindex.dk/jobsoegning?page ={page} &q ={tag}"
    
r = requests.get(url, headers)
    
soup = BeautifulSoup(r.content.decode("utf-8"), "html.parser")
    
return soup

def transform(soup):
    divs = soup.find_all("div", class_="jobsearch-result")
    for item in divs:
        title = item.find_all("b")[0].text.strip()
        company = item.find_all("b")[1].text.strip()
        published_date = item.find("time").text.strip()
        summary = item.find_all("p")[1].text.strip()
        job_location = item.find_all("p")[0].text.strip()
        job_url = item.find_all("href")
        
        job = {
            "title" : title, 
            "company" : company,
            "published_date" : published_date,
            "summary" : summary,
            "job_location" : job_location,
            "Job_url" : job_url
        }
        joblist.append(job)

    return

您可以将 attribute = value css 选择器与 contains * 运算符结合使用，以通过子字符串定位 onclick 属性。添加到该选择器列表 :has 以指定具有匹配 onclick 属性的元素必须具有直接子 b 标记，该标记将匹配限制为具有粗体职位的那些

[data-click*="u="]:has(> b)

import requests
from bs4 import BeautifulSoup

def extract(page, tag):
    
    headers = {'User-Agent':'Mozilla/5.0'}
    
    url = f"https://www.jobindex.dk/jobsoegning?page={page}&q={tag}"
    
    r = requests.get(url, headers)

    soup = BeautifulSoup(r.content.decode("utf-8"), "html.parser")
    
    return soup

def transform(soup):
    
    divs = soup.find_all("div", class_="jobsearch-result")
    
    for item in divs:
        title = item.find_all("b")[0].text.strip()
        company = item.find_all("b")[1].text.strip()
        published_date = item.find("time").text.strip()
        summary = item.find_all("p")[1].text.strip()
        job_location = item.find_all("p")[0].text.strip()
        job_url =  item.select_one('[data-click*="u="]:has(> b)')['href']
        
        job = {
            "title" : title, 
            "company" : company,
            "published_date" : published_date,
            "summary" : summary,
            "job_location" : job_location,
            "Job_url" : job_url
        }
        joblist.append(job)

    return

joblist = []
soup = extract(1, "python")
#print(soup)
transform(soup)
print(joblist)
