万有平凡

在学习视频教程时，发现自己编写的代码无法成功访问页面，并出现如下错误：urllib.error.HTTPError: HTTP Error 403: Forbidden
并且代码中已进添加了user agent，代码如下：

1. import urllib.request
   
2. import os
   
3. 
   
4. def url_open(url):
   
5.     req = urllib.request.Request(url)
   
6.     req.add_header('User-Agent', 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.125 Safari/537.36')
   
7.     response = urllib.request.urlopen(url)
   
8.     html = response.read()
   
9. 
   
10.     return html
    
11. 
    
12. url = "http://jandan.net/ooxx/MjAyMDA4MzAtOTA=#comments"
    
13. url_open(url)
