 9 response = requests.get(url, headers=headers)
10 soup = BeautifulSoup(response.text, 'lxml')
11 # soup

第二步：获取首页所有职位链接

# 获取拉勾全网职位链接

all_info = soup.select('div.mainNavs a')
position_urls = []
for i in all_info:
    url = i.get('href')
    position_urls.append(url)
# position_urls

第三步：获取所对应链接的职位招聘信息

# 获取对应链接的职位信息

position_info = []

for i in position_urls:
#     print(i)
    response_i = requests.get(i, headers = headers)
    soup = BeautifulSoup(response_i.text, 'lxml')
#     print(soup)
    con_list = soup.select('ul.item_con_list')[1].select('li')
#     print(con_list[0])

   # 获取职位信息
    for li in con_list:
        dic = {}
        dic['position_name'] = li.select('h3')[0].text
        dic['address'] = li.select('span.add')[0].text
        dic['salary&experience'] = li.select('div.li_b_l')[0].text.split('\n')[1]
        dic['experience'] = li.select('div.li_b_l')[0].text.replace(' ','').split('\n')[2].split('/')[0]
        dic['degree'] = li.select('div.li_b_l')[0].text.replace(' ','').split('\n')[2].split('/')[1]
        dic['job_kind'] = li.select('div.li_b_l')[1].text.replace('\n','/')
        position_info.append(dic)
print(position_info)
