爬取校园新闻首页的新闻

Posted 2020-10-29 zjm85

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

url = \'http://news.gzcc.cn/html/xiaoyuanxinwen/\'
res = requests.get(url)
res.encoding = \'utf-8\'
soup = BeautifulSoup(res.text, \'html.parser\')

news = soup.select(\'li\')
for new in news:
    if len(new.select(\'.news-list-title\')) > 0:
        title = new.select(\'.news-list-title\')[0].text
        href = new.select(\'a\')[0].attrs[\'href\']
        text = new.select(\'.news-list-description\')[0].text
        print(title)
        print(href)
        print(text+\'\\n\')

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。

import requests
from bs4 import BeautifulSoup

url = \'http://news.gzcc.cn/html/xiaoyuanxinwen/\'
res = requests.get(url)
res.encoding = \'utf-8\'
soup = BeautifulSoup(res.text, \'html.parser\')

news = soup.select(\'li\')
for new in news:
    if len(new.select(\'.news-list-title\')) > 0:
        title = new.select(\'.news-list-title\')[0].text
        href = new.select(\'a\')[0].attrs[\'href\']
        text = new.select(\'.news-list-description\')[0].text
        res = requests.get(href)
        res.encoding = \'utf-8\'
        soup = BeautifulSoup(res.text, \'html.parser\')
        info = soup.select(\'.show-info\')[0].text
        content = info.split()
        time = content[0].lstrip(\'发布时间:\') + " " + content[1]
        author = content[2].lstrip(\'作者：\')
        check = content[3].lstrip(\'审核：\')
        source = content[4].lstrip("来源：")
        print(time, author, check, source)

 

3. 将其中的发布时间由str转换成datetime类型。

from datetime import datetime
time = \'2018-04-04 05:20:34\'
a = datetime.strptime(time, \'%Y-%m-%d %H:%M:%S\')
print(type(a))
print(a, a.strftime(\'%Y/%m/%d\'))

 

4. 将完整的代码及运行结果截图发布在作业上。
