Python：urllib2.HTTPError：HTTP错误401：未授权

Question

我试图加载一个网页，但我遇到了这个问题。我有用户名和密码，但我不知道如何在Python代码中使用它们。我查了一下python教程，这就是我写的：

import urllib2 

password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm() 
username = 'user' 
password = 'pass' 
top_level_url = "www.something.com:80" 
password_mgr.add_password(None, top_level_url, username, password) 
handler = urllib2.HTTPBasicAuthHandler(password_mgr) 
opener = urllib2.build_opener(handler) 
opener.open('http://www.something.com/h/h.html') 
urllib2.install_opener(opener) 
response = urllib2.urlopen() 
page = response.read() 
print page 

有什么问题吗？

Answer 1

这里是工作的代码

import urllib2 

url = 'http://www.abc.com/index.html' 
username = 'user' 
password = 'pass' 
p = urllib2.HTTPPasswordMgrWithDefaultRealm() 

p.add_password(None, url, username, password) 

handler = urllib2.HTTPBasicAuthHandler(p) 
opener = urllib2.build_opener(handler) 
urllib2.install_opener(opener) 

page = urllib2.urlopen(url).read() 

Answer 2

我认为你可以使用请求模块，将使其更容易让你。

import requests 
username = 'user' 
password = 'pass' 
url = 'http://www.example.com/index.html' 
r = requests.get(url, auth=(username, password)) 
page = r.content() 
print page
