**题目：**

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

点击：

*  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。

--------------------

newsURL为：

http://news.gzcc.cn/html/2019/xiaoyuanxinwen_0402/11131.html

代码为

# -*- coding: utf-8 -*-
    
    import requests
    from datetime import datetime
    from bs4 import BeautifulSoup
    
    url = 'http://news.gzcc.cn/html/2019/xiaoyuanxinwen_0402/11131.html'
    clickNumURL = 'http://oa.gzcc.cn/api.php?op=count&id=11131&modelid=80'
    
    
    def newsTime(shareinfo):
        newsDate = shareinfo.split()[0].split(':')[1]
        newsTime = shareinfo.split()[1]
        dt = newsDate + " " + newsTime
        # datetime模块的strptime能够将文本字符串格式的数据转换成时间格式的数据
        showtime = datetime.strptime(dt, "%Y-%m-%d %H:%M:%S")
        print("新闻发布时间：", end="")
        print(showtime)
    
    
    
    def click(click_num_url):
        return_click_num = requests.get(click_num_url)
        click_info = BeautifulSoup(return_click_num.text, 'html.parser')
        click_num = int(click_info.text.split('.html')[3].split("'")[1])
        print("点击次数：", end="")
        print(click_num)
    
    resourses = requests.get(url)
    resourses.encoding = 'UTF-8'
    soup = BeautifulSoup(resourses.text, 'html.parser')
    
    print("\n新闻标题：" + soup.select('.show-title')[0].text)  # 使用BeautifulSoup的select方法根据元素的类名来查找元素的内容，返回的是list类型
    publishing_unit = soup.select('.show-info')[0].text.split()[4].split('：')[1]
    print("新闻发布单位：", end="")
    print(publishing_unit)
    print("作者：", end="")
    writer = soup.select('.show-info')[0].text.split()[2].split('：')[1]
    print(writer)
    print("新闻内容：" + soup.select('.show-content')[0].text.replace('\u3000', ''))
    shareinfo = soup.select('.show-info')[0].text
    
    newsTime(shareinfo)
    click(clickNumURL)
