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
import re

res = requests.get("http://news.gzcc.cn/html/xiaoyuanxinwen/")
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)

       

 

        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。

  1. 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)

       

 

        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.完成所有校园新闻的爬取工作。

  1. import requests

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

            print('正文：',text_list)
            
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)

       

 

5.完成自己所选其他主题相应数据的爬取工作。

import requests
from bs4 import BeautifulSoup
import re

url_main="http://www.gamersky.com/"
res = requests.get(url_main)
res.encoding = 'utf-8'


soup = BeautifulSoup(res.text,'html.parser')
 
for news in soup.select('li'):
    if len(news.select('a'))>0:
        title=news.select('a')[0].text
        url=news.select('a')[0]['href']
        #time=news.select('span')[0].contents[0].text
        #print(time,title,url)
        print(title,url)
for i in range(2,pages+1):
    url_page = "http://www.gamersky.com/{}.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)
