爬取新闻列表

一.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 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) print('时间:',time,'\n标题:',title,'\n链接:',href,'\n来源:',info,'\n点击次数:',hits_list,'\n') print('正文:',text_list) break getpageinfo(li)

 

二.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
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)

            print('时间:',time,'\n标题:',title,'\n链接:',href,'\n来源:',info,'\n点击次数:',hits_list,'\n')
            print('正文:',text_list)
            
getpageinfo(li)

 


  

  三.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(''))//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)

 

四.完后所有校园新闻爬取工作

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)

            print('时间:',time,'\n标题:',title,'\n链接:',href,'\n来源:',info,'\n点击次数:',hits_list,'\n')
            print('正文:',text_list)
            #break

getpageinfo(li)

pages = int(soup.select('.a1')[0].text.rstrip(''))//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)
    #break
