点击次数:

import requests
from bs4 import BeautifulSoup
from datetime import datetime


res = requests.get(http://news.gzcc.cn/html//xiaoyuanxinwen/)
res.encoding = utf-8
soup = BeautifulSoup(res.text,html.parser)


for news in soup.select(li):
    if len(news.select(.news-list-title))>0:
        t = news.select(.news-list-title)[0].text
        a = news.select(a)[0][href]
        d = news.select(.news-list-info)[0].contents[0].text
        dt = datetime.strptime(d,%Y-%m-%d)
        s = news.select(.news-list-info)[0].contents[1].text
        #print(t,a,d,s)

        resl = requests.get(a)
        resl.encoding = utf-8
        soupl = BeautifulSoup(resl.text,html.parser)
        ar = soupl.select(.show-content)[0]
        click = requests.get(http://oa.gzcc.cn/api.php?op=count&id=8302&modelid=80).text.split(.)[-1].lstrip("html(‘").rstrip("‘);")
        print(click)
        break

后面函数:

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



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={}&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:
            t = news.select(.news-list-title)[0].text
            a = news.select(a)[0][href]
            d = news.select(.news-list-info)[0].contents[0].text
            dt = datetime.strptime(d,%Y-%m-%d)
            s = news.select(.news-list-info)[0].contents[1].text
            #print(t,a,d,s)

            resl = requests.get(a)
            resl.encoding = utf-8
            soupl = BeautifulSoup(resl.text,html.parser)
            ar = soupl.select(.show-content)[0].text
            click = getclick(a)
            print(click,t,dt,s,a,ar)
getonepage(http://news.gzcc.cn/html/xiaoyuanxinwen/index.html)

res.encoding = utf-8
soup = BeautifulSoup(res.text,html.parser)
page = int(soup.select(.a1)[0].text.rstrip())//10+1
for i in range(2,4):
