获取一篇新闻的全部信息

本次作业的要求来自于：https://edu.cnblogs.com/campus/gzcc/GZCC-16SE2/homework/2894

给定一篇新闻的链接newsUrl，获取该新闻的全部信息标题、作者、发布单位、审核、来源发布时间:转换成datetime类型。

• newsUrl
• newsId(使用正则表达式re)
• clickUrl(str.format(newsId))
• requests.get(clickUrl)
• newClick(用字符串处理，或正则表达式)
• int()

整个过程包装成一个简单清晰的函数。

代码如下：

#!/usr/bin/env python
# _*_ coding:utf-8 _*

import re
import requests
from datetime import datetime
from bs4 import BeautifulSoup

# 获取新闻网页的id
def newsid(url):
    n_id = re.match('http://news.gzcc.cn/html/2019/xiaoyuanxinwen_0314/(.*).html',url).group(1)
    return n_id

def clickcount(url):
    id = re.findall('(\d{1,5})',url)[-1]
    clickurl='http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(id)
    res=requests.get(clickurl)
    click=res.text.split('.html')[-1].lstrip("('").rstrip("');")
    return click

# 转换发布时间类型
def fabushijian(soup):
    date = soup.select('.show-info')[0].text.split()[0].split(':')[1]
    time = soup.select('.show-info')[0].text.split()[1]
    times = date + ' ' + time
    times = datetime.strptime(times,'%Y-%m-%d %H:%M:%S')
    return times

if __name__ == '__main__':
    # 爬取网站的url
    url = 'http://news.gzcc.cn/html/2019/xiaoyuanxinwen_0314/10983.html'
    res = requests.get(url)
    res.encoding = 'utf-8'
    soup = BeautifulSoup(res.text, 'html.parser')
    title = soup.select('.show-title')[0].text
    auditor = soup.select('.show-info')[0].text.split()[3]
    comefrom = soup.select('.show-info')[0].text.split()[4]
    detail = soup.select('.show-content')[0].text
    author = soup.select('.show-info')[0].text.split()[2]
    newsid = newsid(url)
    time = fabushijian(soup)
    clicktime = clickcount(url)
    print(" 编号：" + newsid + '\n'" 标题：" + title + '\n', author + '\n', auditor + '\n',comefrom + '\n'" 正文：" + detail + '\n'" 次数：" + clicktime + '\n 发布时间： ', time)

运行结果如下：
