Question

开发小型Intranet Web服务。我希望在MS AD中使用kerberos或使用基本身份验证对用户进行身份验证。因此我需要在响应401中设置两个“WWW-Authenticate”http标头。如何使用Django进行此操作？

应该是这样的：

Client: GET www/index.html

Server: HTTP/1.1 401 Unauthorized
        WWW-Authenticate: Negotiate
        WWW-Authenticate: Basic realm="corp site"

此代码覆盖标题

def auth(request):
    response = None
    auth = request.META.get('HTTP_AUTHORIZATION')
    if not auth:
        response = HttpResponse(status = 401)
        response['WWW-Authenticate'] = 'Negotiate'
        response['WWW-Authenticate'] = 'Basic realm="  trolls place basic auth"'

    elif auth.startswith('Negotiate YII'):
        ...

    return response

我认为中间件最适合这项任务，但是如果您还有其他想法，请调整中间件代码以适应您的视图（如果您决定使用，您可以很容易地转变为中间件这样做）：

from django.conf import settings
from django.http import HttpResponse

def basic_challenge(realm=None):
    if realm is None:
        realm = getattr(settings,
                        'WWW_AUTHENTICATION_REALM',
                        'Restricted Access')
    response = HttpResponse('Authorization Required',
                            mimetype="text/plain")
    response['WWW-Authenticate'] = 'Basic realm="%s"' % (realm)
    response.status_code = 401
    return response

def basic_authenticate(authentication):
    (authmeth, auth) = authentication.split(' ', 1)
    if 'basic' != authmeth.lower():
        return None

    auth = auth.strip().decode('base64')
    username, password = auth.split(':', 1)
    AUTHENTICATION_USERNAME = getattr(settings,
                                      'BASIC_WWW_AUTHENTICATION_USERNAME')
    AUTHENTICATION_PASSWORD = getattr(settings,
                                      'BASIC_WWW_AUTHENTICATION_PASSWORD')
    return (username == AUTHENTICATION_USERNAME and
            password == AUTHENTICATION_PASSWORD)

def auth_view(request):
    auth = request.META.get('HTTP_AUTHORIZATION', '')

    if auth.startswith('Negotiate YII'):
        pass
    elif auth:
        if basic_authenticate(auth):
            #successfully authenticated
            pass
        else:
            return basic_challenge()

    # nothing matched, still return basic challange
    return basic_challenge()
