[英]Basic auth protected views in DRF
我有一些 API 端点,我需要使用 Django Z55276C10D84E1DF74E71B3 中的 HTTP 基本身份验证来保护这些端点。 DRF 中有BasicAuthentication ,但实际上对 Django 中的用户进行身份验证,这不是我想要的。
我找到了使用自定义权限的解决方案,但 ti 意味着猴子修补视图以设置正确的身份验证 header。
有没有更好的办法?
class BasicAuthPermission(permissions.BasePermission):
def has_permission(self, request, view):
credentials = view.credentials # Will raise AttributeError on missing credentials
realm = getattr(view, 'realm', 'Protected')
auth = request.headers.get('Authorization')
with suppress(ValueError, AttributeError):
auth = b64decode(auth.split()[-1]).decode()
if auth != credentials:
# Monkey patch style
view.get_authenticate_header = lambda r: f'Basic realm="{realm}"'
raise exceptions.AuthenticationFailed('Bad credentials.')
return True
我的观点:
class ProtectedApiView(generics.GenericAPIView):
permission_classes = [BasicAuthPermission]
credentials = 'user:password'
# ...
按照 Arakkal 在评论中的建议,我使用 Authentication class 来代替。 它确实感觉不那么hacky,但我不能像我最初那样在视图上设置凭据。
我意识到“匿名身份验证”是一个奇怪的名称,但那是因为 Django 对用户一无所知。 因此,出于所有实际目的,匿名。
from base64 import b64decode

from rest_framework import generics, exceptions, authentication

credentials: str = None
def authenticate(self, request):
try:
auth, encoded = authentication.get_authorization_header(request).split(maxsplit=1)
except ValueError:
raise exceptions.AuthenticationFailed('Invalid basic header.')
if not auth or auth.lower() != b'basic':
raise exceptions.AuthenticationFailed('Authentication needed')
try:
credentials = b64decode(encoded).decode(authentication.HTTP_HEADER_ENCODING)
except (TypeError, UnicodeDecodeError, binascii.Error):
raise exceptions.AuthenticationFailed('Invalid basic header. Credentials not correctly base64 encoded.')
if self.credentials != credentials:
raise exceptions.AuthenticationFailed('Invalid username/password.')
def authenticate_header(self, request):
return 'Basic realm="{}"'.format(self.www_authenticate_realm)
class MyAuthentication(AnonymousBasicAuthentication):
credentials = 'user:password'
class MyProtectedView(generics.GenericAPIView):
authentication_classes = [MyAuthentication]
