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
import re
from bs4 import BeautifulSoup
from datetime import datetime

def getchick(url):
    t = re.match('http://news.gzcc.cn/html/2017/xiaoyuanxinwen_(.*).html',url).groups()
    id = t[0].split('/')[1]
    chickurl = 'http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(id)
    chick = int(requests.get(chickurl).text.split('.')[-1].lstrip("html('").rstrip("');"))
    return(chick)

gzccurl = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
res = requests.get(gzccurl)
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 #标题
        url = news.select('a')[0]['href'] #路径
        time = news.select('.news-list-info')[0].contents[0].text #时间
        dt = datetime.strptime(time,'%Y-%m-%d')
        source = news.select('.news-list-info')[0].contents[1].text #来源
        #正文
        resd = requests.get(url)
        resd.encoding='utf-8'
        soupd = BeautifulSoup(resd.text,'html.parser')
        detail = soupd.select('.show-content')[0].text
        chick = getchick(url)
        print(title,chick,url,dt,source,detail)
        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
import re
from bs4 import BeautifulSoup
from datetime import datetime

def getchick(url):
    t = re.match('http://news.gzcc.cn/html/2017/xiaoyuanxinwen_(.*).html',url).groups()
    id = t[0].split('/')[1]
    chickurl = 'http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(id)
    chick = int(requests.get(chickurl).text.split('.')[-1].lstrip("html('").rstrip("');"))
    return(chick)
def getonepage(url):
    for news in soup.select('li'):
        if len(news.select('.news-list-title'))>0:
            title = news.select('.news-list-title')[0].text #标题
            url = news.select('a')[0]['href'] #路径
            time = news.select('.news-list-info')[0].contents[0].text #时间
            dt = datetime.strptime(time,'%Y-%m-%d')
            source = news.select('.news-list-info')[0].contents[1].text #来源
        #正文
            resd = requests.get(url)
            resd.encoding='utf-8'
            soupd = BeautifulSoup(resd.text,'html.parser')
            detail = soupd.select('.show-content')[0].text
            chick = getchick(url)
            print(title,chick,url,dt,source,detail)
gzccurl = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
res = requests.get(gzccurl)
res.encoding='utf-8'
soup = BeautifulSoup(res.text,'html.parser')

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

 

3、获取所有新闻列表页的网址，调用上述函数

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

def getdetail(url):
    resd = requests.get(url)
    resd.encoding='utf-8'
    soupd = BeautifulSoup(resd.text,'html.parser')
    detail = soupd.select('.show-content')[0].text
    return(detail)
def getchick(newsurl):
    id = re.match('http://news.gzcc.cn/html/2017/xiaoyuanxinwen_(.*).html',newsurl).groups()[-1].split('/')[1]
    chickurl = 'http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(id)
    chick = int(requests.get(chickurl).text.split('.')[-1].lstrip("html('").rstrip("');"))
    return(chick)
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 #标题
            url = news.select('a')[0]['href'] #路径
            time = news.select('.news-list-info')[0].contents[0].text #时间
            dt = datetime.strptime(time,'%Y-%m-%d')
            source = news.select('.news-list-info')[0].contents[1].text #来源
        #正文
            detail = getdetail(url)
            chick = getchick(url)
            #print(title,chick,url,dt,source,detail)

gzccurl = 'http://news.gzcc.cn/html/xiaoyuanxinwen/'
res = requests.get(gzccurl)
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)
    print(listurl)

4、完成所有校园新闻的爬取工作

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

def getdetail(url):
    resd = requests.get(url)
    resd.encoding='utf-8'
    soupd = BeautifulSoup(resd.text,'html.parser')
    detail = soupd.select('.show-content')[0].text
    return(detail)
def getchick(newsurl):
    id = re.match('http://news.gzcc.cn/html/2017/xiaoyuanxinwen_(.*).html',newsurl).groups()[-1].split('/')[1]
    chickurl = 'http://oa.gzcc.cn/api.php?op=count&id={}&modelid=80'.format(id)
    chick = int(requests.get(chickurl).text.split('.')[-1].lstrip("html('").rstrip("');"))
    return(chick)
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 #标题
