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].texturl = news.select('a')[0]['href']time = news.select('.news-list-info')[0].contents[0].textmain = news.select('.news-list-description')[0].textsource = news.select('.news-list-info')[0].contents[1].textprint('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 renetwork = '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].texturl = news.select('a')[0]['href']time = news.select('.news-list-info')[0].contents[0].texttimed = datetime.strptime(time,'%Y-%m-%d')main = news.select('.news-list-description')[0].textsource = news.select('.news-list-info')[0].contents[1].textprint('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 reurl_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 hitsdef 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].texttime = title_list.select('span')[0].textinfo = title_list.select('span')[1].textres_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].texthits_list = gethits(href)getpageinfo(li)pages = int(soup.select('.a1')[0].text.rstrip('条'))//10+1for 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 redef 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].texturl = news.select('a')[0]['href']time = news.select('.news-list-info')[0].contents[0].texttimed = datetime.strptime(time,'%Y-%m-%d')main = news.select('.news-list-description')[0].textsource = news.select('.news-list-info')[0].contents[1].textprint('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)
