作业:获取一篇新闻的全部信息

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

 

我爬取的网页是某高校的新闻信息网站:http://news.gzcc.cn/html/2019/xiaoyuanxinwen_0328/11086.html。

代码如下:

# -*- coding: utf-8 -*-

 # -*- coding: UTF-8 -*- 
#导入包
import requests                                                            # 直接导入requests模块
import re                                                                  # 直接导入re模块
from datetime import datetime                                              # 从datetime包导入datetime模块
from bs4 import BeautifulSoup                                              # 从bs4包导入BeautifulSoup模块

html_url = 'http://news.gzcc.cn/html/2019/xiaoyuanxinwen_0328/11086.html'  # 校园新闻url
click_num_url = 'http://oa.gzcc.cn/api.php?op=count&id=11086&modelid=80'   # 点击次数url

def newsdt(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")                  # strptime():将字符串类型转换成时间类型
    print("新闻发布时间:", end="")
    print(showtime)

#————————————点击次数——————————————
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)

# 用requests库和BeautifulSoup库,爬取校园新闻首页新闻的标题、链接、正文、点击量等信息。
def anews(html_url):
    resourses = requests.get(html_url)                                         # 发送get请求
    resourses.encoding = 'UTF-8'                                               # 以防获取的内容出现乱码,手动指定字符编码为UTF-8
    soup = BeautifulSoup(resourses.text, 'html.parser')                        # 调用BeautifulSoup解析功能,解析请求返回的内容,解析器用html.parser
#————————————输出内容——————————————
    print("获取的head标签内容:")
    print(soup.head)
    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
# 调用函数
    newsdt(shareinfo)
    click(click_num_url)
   
anews(html_url)

运行结果如下:
