HTTPS log in with urllib2
提问by Parker Coates
I currently have a little script that downloads a webpage and extracts some data I'm interested in. Nothing fancy.
我目前有一个小脚本，可以下载网页并提取一些我感兴趣的数据。没什么特别的。
Currently I'm downloading the page like so:
目前我正在像这样下载页面：
import commands
command = 'wget --output-document=- --quiet --http-user=USER --http-password=PASSWORD https://www.example.ca/page.aspx'
status, text = commands.getstatusoutput(command)
Although this works perfectly, I thought it'd make sense to remove the dependency on wget. I thought it should be trivial to convert the above to urllib2, but thus far I've had zero success. The Internet is full urllib2 examples, but I haven't found anything that matches my need for simple username and password HTTP authentication with a HTTPS server.
虽然这很有效，但我认为消除对 wget 的依赖是有意义的。我认为将上述内容转换为 urllib2 应该很简单，但到目前为止我的成功率为零。互联网上有完整的 urllib2 示例，但我没有找到任何符合我对使用 HTTPS 服务器进行简单用户名和密码 HTTP 身份验证的需求的内容。

thissays, it should be straight forward
这说，它应该是直截了当的
[as] long as your local Python has SSL support.
[只要] 本地 Python 支持 SSL。
If you use just HTTP Basic Authentication, you must set different handler, as described here.
如果你只使用HTTP基本身份验证，则必须设置不同的处理程序，如所描述这里。
Quoting the example there:
引用那里的例子：
import urllib2
theurl = 'http://www.someserver.com/toplevelurl/somepage.htm'
username = 'johnny'
password = 'XXXXXX'
# a great password
passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
# this creates a password manager
passman.add_password(None, theurl, username, password)
# because we have put None at the start it will always
# use this username/password combination for urls
# for which `theurl` is a super-url
authhandler = urllib2.HTTPBasicAuthHandler(passman)
# create the AuthHandler
opener = urllib2.build_opener(authhandler)
urllib2.install_opener(opener)
# All calls to urllib2.urlopen will now use our handler
# Make sure not to include the protocol in with the URL, or
# HTTPPasswordMgrWithDefaultRealm will be very confused.
# You must (of course) use it when fetching the page though.
pagehandle = urllib2.urlopen(theurl)
# authentication is now handled automatically for us
If you do Digest, you'll have to set some additional headers, but they are the same regardless of SSL usage. Googlefor python+urllib2+http+digest.
如果您执行 Digest，则必须设置一些额外的标头，但无论 SSL 使用情况如何，它们都是相同的。谷歌搜索 python+urllib2+http+digest。
Cheers,
干杯，

The urllib2 documentation has an example of working with Basic Authentication:
urllib2 文档有一个使用基本身份验证的示例：
