使用urllib2进行Python身份验证

Question

So I'm trying to download a file from a site called vsearch.cisco.com with python

[python]

#Connects to the Cisco Server and Downloads files at the URL specified

import urllib2

#Define Useful Variables

url = 'http://vsearch.cisco.com'
username = 'xxxxxxxx'
password = 'xxxxxxxx'
realm = 'CEC'

# Begin Making connection

# Create a Handler -- Also could be where the error lies

handler = urllib2.HTTPDigestAuthHandler()
handler.add_password(realm,url,username,password)

# Create an Opener

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

try:
    urllib2.urlopen(url)
    print f.read()

except urllib2.HTTPError, e:
    print e.code
    print e.header

[/python]

My error is ValueError: AbstractDigestAuthHandler doesn't know about basic

I've tried using Basic HTML Authorization handlers and even HTTPS handlers. Nothing gives me access. This error is different from all the other errors however. The other errors are simply 401 HTML errors

Any suggestions on how to do this?

Answer 1

A "password manager" might help:

    mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
    mgr.add_password(None, url, user, password)        
    urllib2.build_opener(urllib2.HTTPBasicAuthHandler(mgr),
                         urllib2.HTTPDigestAuthHandler(mgr))

至于我在测试中尝试的内容（ http://devel.almad.net/trac/django-http-digest/browser/djangohttpdigest/tests/test_simple_digest.py ），您的网址中出现错误 - 要使其正常工作，我已经包含了http：// part，而不仅仅是主机。
