1. 用requests库和BeautifulSoup库,爬取校园新闻首页新闻的标题、链接、正文。

import requests
from bs4 import BeautifulSoup

res = requests.get('http://news.gzcc.cn/html/xibusudi/')
res.encoding = 'UTF-8'
soup = BeautifulSoup(res.text, 'html.parser')
# print(soup)
for news in soup.select('li'):
    if len(news.select('.news-list-text'))>0:
        time = news.select('.news-list-info')[0].contents[0].text
        name = news.select('.news-list-title')[0].text
        sout= news.select('.news-list-info')[0].contents[1].text
        print(time,name,sout)
        link = news.select('a')[0].attrs['href']
        resd = requests.get(link)
        resd.encoding = 'UTF-8'
        soupd = BeautifulSoup(resd.text, 'html.parser')
        print(soupd.select('#content')[0].text)

2. 分析字符串,获取每篇新闻的发布时间,作者,来源,摄影等信息。

  info = soupd.select('.show-info')[0].text
        # print(info)
        dt = info.lstrip('发布时间:')[:19]
        at = info[info.find('作者:'):].split()[0].lstrip('作者:')
        sh = info[info.find('审核:'):].split()[0].lstrip('审核:')
        ly = info[info.find('来源:'):].split()[0].lstrip('来源:')
        print(dt, at, sh, ly)

3. 将其中的发布时间由str转换成datetime类型。

dati = datetime.strptime(dt, '%Y-%m-%d %H:%M:%S')
        print(dati, dati.strftime('%Y/%m/%d'))
