Python机械化与NTLM获取AttributeError：HTTPResponse实例没有属性'__iter__'

Question

我正在尝试使用python-ntlm和mechanize访问使用NTLM身份验证进行保护的网站，但我收到此错误。

File "build/bdist.macosx-10.6-universal/egg/mechanize/_mechanize.py", line 203, in open
File "build/bdist.macosx-10.6-universal/egg/mechanize/_mechanize.py", line 249, in _mech_open
File "build/bdist.macosx-10.6-universal/egg/mechanize/_mechanize.py", line 304, in _set_response
File "build/bdist.macosx-10.6-universal/egg/mechanize/_response.py", line 521, in upgrade_response
File "build/bdist.macosx-10.6-universal/egg/mechanize/_response.py", line 338, in __init__
File "build/bdist.macosx-10.6-universal/egg/mechanize/_response.py", line 353, in _set_fp
AttributeError: HTTPResponse instance has no attribute '__iter__'

当我使用urllib2库时，我能够得到正确的响应。但由于某些原因，当我尝试使用mechanize访问它时失败了。

这是我的代码。

import urllib2
from ntlm import HTTPNtlmAuthHandler

user = '<myusername>'
password = "<mypass>"
url = "https://somesite.com"

passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, url, user, password)
# create the NTLM authentication handler
auth_NTLM = HTTPNtlmAuthHandler.HTTPNtlmAuthHandler(passman)

import mechanize
browser = mechanize.Browser()
handlersToKeep = []

for handler in browser.handlers:
    if not isinstance(handler,
    (mechanize._http.HTTPRobotRulesProcessor)):
        handlersToKeep.append(handler)

browser.handlers = handlersToKeep
browser.add_handler(auth_NTLM)

response = browser.open(url)
print(response.read())

有没有人知道发生了什么？我在这里做错了吗？

我修补机械化来解决这个问题：
