Question

import urllib2
proxy = urllib2.ProxyHandler({ "http" : "http:proxyIp1", "https" : "proxyIp2"})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
try:
    a = urllib2.urlopen("corporate internal link")#, proxies=proxy)
    b = a.read()
except urllib2.HTTPError as e:
    error = e.read() # this will be your error message
    print error

这会出错：

401 - Unauthorized: Access is denied due to invalid credentials.

我知道我必须提供“用户名”和“密码”但是可以告诉我如何在这种情况下提供凭据？感谢

来源：http://docs.python.org/2/library/urllib2.html选中“使用基本HTTP身份验证”

了解add_password方法here

proxy_handler = urllib2.ProxyHandler({'http': 'http://www.example.com:3128/'})
proxy_auth_handler = urllib2.ProxyBasicAuthHandler()
proxy_auth_handler.add_password('realm', 'host', 'username', 'password')

opener = urllib2.build_opener(proxy_handler, proxy_auth_handler)
# This time, rather than install the OpenerDirector, we use it directly:
opener.open('http://www.example.com/login.html')

401 - 未经授权：由于证书python无效，访问被拒绝
