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 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) getonepage(‘http://news.gzcc.cn/html/xiaoyuanxinwen/index.html‘) 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): getonepage(‘http://news.gzcc.cn/html/xiaoyuanxinwen/{}.html‘.format(i))
5、完成自己所选其他主题相应数据的爬取工作
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/meitishijie_(.*).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‘) #正文 detail = getdetail(url) chick = getchick(url) print(title,chick,url,dt,detail) getonepage(‘http://news.gzcc.cn/html/meitishijie/index.html‘) gzccurl = ‘http://news.gzcc.cn/html/meitishijie/‘ 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): getonepage(‘http://news.gzcc.cn/html/meitishijie/{}.html‘.format(i))
