Process finished with exit code 1

2.解决办法

在 requests.get() 函数里加 verify=False ,这样客户端就不会校验 SSL；文章来源地址https://www.toymoban.com/news/detail-820772.html

3.正确可执行代码

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# @Time    : 5/8/2023 3:32 PM
# @Author  : Nora
# @File    : build_now.py
# @Description : to show 点击量； 


import requests
from bs4 import BeautifulSoup
import ssl
import urllib


url = 'https://blog.csdn.net/cun_king'
# context = ssl._create_unverified_context()
# data = urllib.request.urlopen(url, context=context).read().decode('utf-8')

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)'
                         'Chrome/112.0.0.0 Safari/537.36'}
strhtml = requests.get(url=url, headers=headers,verify=False)  # Get方式获取网页数据
soup = BeautifulSoup(strhtml.text, 'lxml')
info = soup.select('#userSkin > div.user-profile-head > '
                   'div.user-profile-head-info > div.user-profile-head-info-t > div > div.user-profile-head-info-rr > div.user-profile-head-info-r-c > ul > '
                   'li:nth-child(1) > span > span > span > div.user-profile-statistics-num')
print("访问量：" + info[0].get_text())

4.结果展示：
