如何使用 DRF djangorestframework-simplejwt 包将 JWT 令牌存储在 HttpOnly cookie 中？

Question

我已经使用 djangorestframework-simplejwt 一段时间了，现在我想将 JWT 存储在 cookie 中（而不是本地存储或前端状态），以便客户端发出的每个请求都包含令牌。

因此对其进行了一些研究，我发现最相关的结果是 , in which the author is using djangorestframework-jwt package which has a pre-configured setting for cookies called JWT_AUTH_COOKIE. So figured switching to that package but then ended up finding out that the package is pretty much dead。

虽然建议使用 djangorestframework-jwt 的 fork，但我想知道是否可以使用 djagnorestframework_simplejwt 本身在 HttpOnly cookie 中设置 JWT？

使用 httponly cookie 标志和 CSRF 保护遵循此代码。

双方在移动应用程序和网络应用程序中都非常有用..

urls.py:

...
path('login/',LoginView.as_view(),name = "login"),
...

view.py:

from rest_framework_simplejwt.tokens import RefreshToken
from django.middleware import csrf

def get_tokens_for_user(user):
    refresh = RefreshToken.for_user(user)
        
    return {
        'refresh': str(refresh),
        'access': str(refresh.access_token),
    }

class LoginView(APIView):
    def post(self, request, format=None):
        data = request.data
        response = Response()        
        username = data.get('username', None)
        password = data.get('password', None)
        user = authenticate(username=username, password=password)
        if user is not None:
            if user.is_active:
                data = get_tokens_for_user(user)
                response.set_cookie(
                                    key = settings.SIMPLE_JWT['AUTH_COOKIE'], 
                                    value = data["access"],
                                    expires = settings.SIMPLE_JWT['ACCESS_TOKEN_LIFETIME'],
                                    secure = settings.SIMPLE_JWT['AUTH_COOKIE_SECURE'],
                                    httponly = settings.SIMPLE_JWT['AUTH_COOKIE_HTTP_ONLY'],
                                    samesite = settings.SIMPLE_JWT['AUTH_COOKIE_SAMESITE']
                                        )
                csrf.get_token(request)
                email_template = render_to_string('login_success.html',{"username":user.username})    
                login = EmailMultiAlternatives(
                    "Successfully Login", 
                    "Successfully Login",
                    settings.EMAIL_HOST_USER, 
                    [user.email],
                )
                login.attach_alternative(email_template, 'text/html')
                login.send()
                response.data = {"Success" : "Login successfully","data":data}
                
                return response
            else:
                return Response({"No active" : "This account is not active!!"},status=status.HTTP_404_NOT_FOUND)
        else:
            return Response({"Invalid" : "Invalid username or password!!"},status=status.HTTP_404_NOT_FOUND)

authenticate.py:

from rest_framework_simplejwt.authentication import JWTAuthentication
from django.conf import settings

from rest_framework.authentication import CSRFCheck
from rest_framework import exceptions

def enforce_csrf(request):
    """
    Enforce CSRF validation.
    """
    check = CSRFCheck()
    # populates request.META['CSRF_COOKIE'], which is used in process_view()
    check.process_request(request)
    reason = check.process_view(request, None, (), {})
    if reason:
        # CSRF failed, bail with explicit error message
        raise exceptions.PermissionDenied('CSRF Failed: %s' % reason)

class CustomAuthentication(JWTAuthentication):
    
    def authenticate(self, request):
        header = self.get_header(request)
        
        if header is None:
            raw_token = request.COOKIES.get(settings.SIMPLE_JWT['AUTH_COOKIE']) or None
        else:
            raw_token = self.get_raw_token(header)
        if raw_token is None:
            return None

        validated_token = self.get_validated_token(raw_token)
        enforce_csrf(request)
        return self.get_user(validated_token), validated_token

settings.py:

....
REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'authentication.authenticate.CustomAuthentication',
    ),
}

SIMPLE_JWT = {
.....
'AUTH_COOKIE': 'access_token',  # Cookie name. Enables cookies if value is set.
'AUTH_COOKIE_DOMAIN': None,     # A string like "example.com", or None for standard domain cookie.
'AUTH_COOKIE_SECURE': False,    # Whether the auth cookies should be secure (https:// only).
'AUTH_COOKIE_HTTP_ONLY' : True, # Http only cookie flag.It's not fetch by javascript.
'AUTH_COOKIE_PATH': '/',        # The path of the auth cookie.
'AUTH_COOKIE_SAMESITE': 'Lax',  # Whether to set the flag restricting cookie leaks on cross-site requests.
                                # This can be 'Lax', 'Strict', or None to disable the flag.

您可以执行以下操作以将刷新令牌存储在 httpOnly cookie 中：

将此添加到 views.py：

# views.py
from rest_framework_simplejwt.views import TokenRefreshView, TokenObtainPairView
from rest_framework_simplejwt.serializers import TokenRefreshSerializer
from rest_framework_simplejwt.exceptions import InvalidToken

class CookieTokenRefreshSerializer(TokenRefreshSerializer):
    refresh = None
    def validate(self, attrs):
        attrs['refresh'] = self.context['request'].COOKIES.get('refresh_token')
        if attrs['refresh']:
            return super().validate(attrs)
        else:
            raise InvalidToken('No valid token found in cookie \'refresh_token\'')

class CookieTokenObtainPairView(TokenObtainPairView):
  def finalize_response(self, request, response, *args, **kwargs):
    if response.data.get('refresh'):
        cookie_max_age = 3600 * 24 * 14 # 14 days
        response.set_cookie('refresh_token', response.data['refresh'], max_age=cookie_max_age, httponly=True )
        del response.data['refresh']
    return super().finalize_response(request, response, *args, **kwargs)

class CookieTokenRefreshView(TokenRefreshView):
    def finalize_response(self, request, response, *args, **kwargs):
        if response.data.get('refresh'):
            cookie_max_age = 3600 * 24 * 14 # 14 days
            response.set_cookie('refresh_token', response.data['refresh'], max_age=cookie_max_age, httponly=True )
            del response.data['refresh']
        return super().finalize_response(request, response, *args, **kwargs)
    serializer_class = CookieTokenRefreshSerializer

更改 url.py 中的 url 以使用这些视图获取和刷新令牌：

# url.py
from .views import CookieTokenRefreshView, CookieTokenObtainPairView # Import the above views
# [...]
urlpatterns = [
    path('auth/token/', CookieTokenObtainPairView.as_view(), name='token_obtain_pair'),
    path('auth/token/refresh/', CookieTokenRefreshView.as_view(), name='token_refresh'),
    # [...]
]

如果它没有按预期工作，请检查您的 CORS 设置：也许您必须设置 sameSite 并确保 set_cookie

工作流程 - 使用凭据获取令牌对

POST /auth/token 凭据有效
在响应正文中，您会注意到仅设置了 'access' 键
'refresh' 键已移至名为 'refresh_token'

工作流程 - 使用刷新令牌获取访问（和可选的刷新）令牌

POST /auth/token/刷新之前设置的cookie 工作流程，正文可以为空
在响应正文中，您会注意到仅设置了 'access' 键
如果你设置了ROTATE_REFRESH_TOKENS，httpOnly cookie 'refresh_token' 包含一个新的刷新令牌
