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))
