统计csdn博客的访问量+评论数

两周前，ip被封了，所以爬虫有风险，访问需谨慎，还好有代理IP

# coding=utf-8
import requests
from bs4 import BeautifulSoup
#总的访问量+评论数
sum = 0
#20是页数，自己设
for i in range(20):
    print("第",i+1,"页")
    url = +str(i+1)
    headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36"}
    html = requests.get(url,  headers=headers)
    soup = BeautifulSoup(html.text, features="html.parser")
    for i in soup.find_all("span" , "read-num"):
        num = i.string
        sum += int(num.split("：")[1])
print(sum)
