1. 用requests库和BeautifulSoup库，爬取校园新闻首页新闻的标题、链接、正文、show-info。
#coding=utf-8 import requests from bs4 import BeautifulSoup res=requests.get(‘http://news.gzcc.cn/html/xiaoyuanxinwen/‘) res.encoding=‘utf-8‘ soup=BeautifulSoup(res.text,‘html.parser‘) soup # print(soup) for i in soup.select(‘li‘): if len(i.select(‘.news-list-title‘))>0: x=i.select(‘.news-list-title‘)[0].text y=i.select(‘.news-list-description‘)[0].text z=i.select(‘.news-list-info‘)[0].text p = i.select(‘a‘)[0].attrs[‘href‘] print(x,y) print(z,p)

2. 分析info字符串，获取每篇新闻的发布时间，作者，来源，摄影等信息。
for i in soup.select(‘li‘): if len(i.select(‘.news-list-title‘))>0: a=i.select(‘.news-list-title‘)[0].text b=i.select(‘.news-list-description‘)[0].text # c=i.a.attrs[‘href‘] c=i.select(‘a‘)[0].attrs[‘href‘] read=requests.get(c) read.encoding=‘utf-8‘ soupSecond=BeautifulSoup(read.text,‘html.parser‘) d=soupSecond.select(‘#content‘)[0].text print(soupSecond.select(‘.show-info‘)[0].text)
