python urllib2 基本身份验证 [英] python urllib2 basic authentication

问题描述

我正在尝试使用 python 访问使用 urllib2 的 API URL:

Hi i'm trying to use python to access an API URL using urllib2:

import urllib2

url = 'https://XXXXXXXXXX.com/'
username = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
password = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'

passman = urllib2.HTTPPasswordMgrWithDefaultRealm()
passman.add_password(None, url, username, password)
authhandler = urllib2.HTTPBasicAuthHandler(passman)
opener = urllib2.build_opener(authhandler)
urllib2.install_opener(opener)
pagehandle = urllib2.urlopen(url)

我不知道领域是什么，但我假设我可以使用默认值，即无.

I don't know what the realm is but am assuming I can use default i.e. None.

无论如何，我仍然收到 401 错误:

Anyway, i am still get 401 error:

所以看起来身份验证有问题.最有可能使用realm = None吗?

so it seems there is something wrong with the authentication. Is it most likely the use of realm = None?

谢谢！

推荐答案

我不明白为什么这个方法不起作用，但我成功地使用以下代码调用了 API:

I could not figure out why this method did not work but I was successful in calling the API using this code:

base64string = base64.encodestring('%s:%s' % (username, password)).replace('\n', '')

request = urllib2.Request(url)

request.add_header("Authorization", "Basic %s" % base64string) 

result = urllib2.urlopen(request)
        data = result.read()
