爬取所有校园新闻

1.获取单条新闻的#标题#链接#时间#来源#内容 #点击次数，并包装成一个函数。

import requests
from bs4 import BeautifulSoup
network = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
res = requests.get(network)
res.encoding='utf-8'
soup = BeautifulSoup(res.text,'html.parser')

for news in soup.select('li'):
    if len(news.select('.news-list-title'))>0:
        title = news.select('.news-list-title')[0].text
        url = news.select('a')[0]['href']
        time = news.select('.news-list-info')[0].contents[0].text
        main = news.select('.news-list-description')[0].text
        source = news.select('.news-list-info')[0].contents[1].text
        print('链接：{}'.format(url))
        print('标题：{}'.format(title))
        print('正文：{}'.format(main))
        print('时间：{}'.format(time))
        print('来源：{}'.format(source))

        res1 = requests.get(url)
        res1.encoding='utf-8'
        soup1 = BeautifulSoup(res1.text,'html.parser')
        passage = soup1.select('.show-content')
        click = int(requests.get('http://oa.gzcc.cn/api.php?op=count&id=8307&modelid=80').text.split('.')[-1].lstrip("html('").rstrip("');"))
        print('点击次数：{}'.format(click))
        break

 

 

2.获取一个新闻列表页的所有新闻的上述详情，并包装成一个函数。

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

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

def getclick(newsurl):
    id = re.match('http://news.gzcc.cn/html/2017/xiaoyuanxinwen_(.*).html',newsurl).groups()[0].split('/')[1]
    clickurl = 'http://oa.gzcc.cn/api.php?op=count&id=8307&modelid=80'.format(id)
    click = int(requests.get(clickurl).text.split('.')[-1].lstrip("html('").rstrip("');"))
    return(click)
       
for news in soup.select('li'):
    if len(news.select('.news-list-title'))>0:
        title = news.select('.news-list-title')[0].text
        url = news.select('a')[0]['href']
        time = news.select('.news-list-info')[0].contents[0].text
        timed = datetime.strptime(time,'%Y-%m-%d')
        main = news.select('.news-list-description')[0].text
        source = news.select('.news-list-info')[0].contents[1].text
        print('链接：{}'.format(url))
        print('标题：{}'.format(title))
        print('正文：{}'.format(main))
        print('时间：{}'.format(timed))
        print('来源：{}'.format(source))

        res1 = requests.get(url)
        res1.encoding='utf-8'
        soup1 = BeautifulSoup(res1.text,'html.parser')
        passage = soup1.select('.show-content')
        click = getclick(url)
        print('点击次数：{}'.format(click))          

 

3.获取所有新闻列表页的网址，调用上述函数。 

import requests
from bs4 import BeautifulSoup
import re

url_main="http://news.gzcc.cn/html/xiaoyuanxinwen/"
res = requests.get(url_main)
res.encoding = 'utf-8'

soup = BeautifulSoup(res.text,'html.parser')
li = soup.select('li')

def gethits(url_1):
    li_id =re.search('_.*/(.*).html',url_1).groups(0)[0]
    hits = requests.get('http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(li_id)).text.split('.')[-1].rstrip('''');''').lstrip(''''html(''')
    return hits

def getpageinfo(label):
    for title_list in label:
        if len(title_list.select('.news-list-title'))>0:
            href = title_list.select('a')[0]['href']
            title = title_list.select('.news-list-title')[0].text
            time = title_list.select('span')[0].text
            info = title_list.select('span')[1].text

            res_list = requests.get(href)
            res_list.encoding = 'utf-8'
            soup_list = BeautifulSoup(res_list.text,'html.parser')
            text_list = soup_list.select('.show-content')[0].text

            hits_list = gethits(href)


getpageinfo(li)

pages = int(soup.select('.a1')[0].text.rstrip('条'))//10+1

for i in range(2,pages+1):
    url_page = "http://news.gzcc.cn/html/xiaoyuanxinwen/{}.html".format(i)
    
    res_page = requests.get(url_page)
    res_page.encoding = 'utf-8'

    soup_page = BeautifulSoup(res_page.text,'html.parser')
    list_page = soup.select('li')

    getpageinfo(list_page)
    print(url_page)

4.完后所有校园新闻爬取工作

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

def getclick(newsurl):
    id = re.match('http://news.gzcc.cn/html/2017/xiaoyuanxinwen_(.*).html',newsurl).groups()[0].split('/')[1]
    clickurl = 'http://oa.gzcc.cn/api.php?op=count&id=8307&modelid=80'.format(id)
    click = int(requests.get(clickurl).text.split('.')[-1].lstrip("html('").rstrip("');"))
    return(click)

def getonepage(listurl):
    res = requests.get(listurl)
    res.encoding='utf-8'
    soup = BeautifulSoup(res.text,'html.parser')
    
    for news in soup.select('li'):
      if len(news.select('.news-list-title'))>0:
        title = news.select('.news-list-title')[0].text
        url = news.select('a')[0]['href']
        time = news.select('.news-list-info')[0].contents[0].text

        main = news.select('.news-list-description')[0].text
        source = news.select('.news-list-info')[0].contents[1].text
        print('链接：{}'.format(url))
        print('标题：{}'.format(title))
        print('正文：{}'.format(main))
        print('时间：{}'.format(timed))
        print('来源：{}'.format(source))

        res1 = requests.get(url)
        res1.encoding='utf-8'
        soup1 = BeautifulSoup(res1.text,'html.parser')
        click = getclick(url)
        print('点击次数：{}'.format(click))

getonepage('http://news.gzcc.cn/html/xiaoyuanxinwen/index.html')

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

page = int(soup.select('.a1')[0].text.rstrip('条'))//10+1
for i in range(2,page+1):
        listurl='http://news.gzcc.cn/html/xiaoyuanxinwen/{}.html'.format(i)
        getonepage(listurl)
