1，默认城市是杭州，代码如下

#! -*-coding:utf-8 -*-

from urllib import request, parse

from bs4 import BeautifulSoup

import datetime

import xlwt

starttime = datetime.datetime.now()

url = r'https://www.zhipin.com/job_detail/?scity=101210100'

# boss直聘的url地址，默认杭州

def read_page(url, page_num, keyword): # 模仿浏览器

  page_headers = {

    'Host': 'www.zhipin.com',

    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36 '

           'Chrome/45.0.2454.85 Safari/537.36 115Browser/6.0.3',

    'Connection': 'keep-alive'

    }

  page_data = parse.urlencode([  # 浏览器请求的参数

    ('ka', 'page-'+str(page_num)),

('page', page_num),

    ('query', keyword)

    ])

  req = request.Request(url, headers=page_headers)

  page = request.urlopen(req, data=page_data.encode('utf-8')).read()

  page = page.decode('utf-8')

  return page

if __name__ == '__main__':

  print('**********************************即将进行抓取**********************************')

  keyword = input('请输入您要搜索的职位：')

  workbook = xlwt.Workbook()

  sheet = workbook.add_sheet('sheet1')

  i=0

  for j in range(1,5):

   soup=BeautifulSoup(read_page(url, j, keyword))

   for link in soup.select('.company-text'):

     sheet.write(i,0,link.get_text())

     i=i+1

  workbook.save("D:\\resultsLatest.xls")

  endtime = datetime.datetime.now()

  time = (endtime - starttime).seconds

  print('总共用时：%s s' % time)
