我正在做一个django项目，使用dj-rest-auth和jwt token。当注册用户时，程序生成一个刷新令牌沿着访问令牌，但是当登录时，它只生成访问令牌，刷新令牌是一个空字符串“"。
我找不到类似的问题，也找不到解决办法。
以下是我的settings.py：

这里是我的urls.py

from django.urls import include, path
from rest_framework import routers
from .views import CustomUserViewSet
from rest_framework_simplejwt.views import (
    TokenObtainPairView,
    TokenRefreshView,
)
from dj_rest_auth.views import PasswordResetConfirmView


router = routers.DefaultRouter()
router.register(r'users', CustomUserViewSet)

urlpatterns = [
    path('', include(router.urls)),
    path('api-auth/', include('rest_framework.urls', namespace='rest_framework')),
    path('token/', TokenObtainPairView.as_view(), name='token_obtain_pair'), 
    path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'),
    path('dj-rest-auth/', include('dj_rest_auth.urls')),
    path('dj-rest-auth/registration/', include('dj_rest_auth.registration.urls')),
    path('dj-rest-auth/password/reset/confirm/<str:uidb64>/<str:token>', PasswordResetConfirmView.as_view(),
            name='password_reset_confirm'),
]

下面是我在dj-rest-auth/login端点输入我的信息时得到的结果：

正如您所看到的，没有生成刷新令牌。
下面是我的serializer：

from .models import CustomUser
from rest_framework import serializers
from dj_rest_auth.serializers import UserDetailsSerializer

class CustomUserSerializer(serializers.ModelSerializer):
    class Meta:
        model = CustomUser
        fields = ('id', 'username', 'email', 'first_name', 'last_name', 'name')

class CustomUserDetailsSerializer(UserDetailsSerializer):

    class Meta:
        model = CustomUser
        fields = UserDetailsSerializer.Meta.fields + ('name',)

编辑：我发现在dj-rest-auth的源代码中，在LoginView中，他们的代码是这样写的：

def get_response(self):
        serializer_class = self.get_response_serializer()

        if api_settings.USE_JWT:
            from rest_framework_simplejwt.settings import (
                api_settings as jwt_settings,
            )
            access_token_expiration = (timezone.now() + jwt_settings.ACCESS_TOKEN_LIFETIME)
            refresh_token_expiration = (timezone.now() + jwt_settings.REFRESH_TOKEN_LIFETIME)
            return_expiration_times = api_settings.JWT_AUTH_RETURN_EXPIRATION
            auth_httponly = api_settings.JWT_AUTH_HTTPONLY

            data = {
                'user': self.user,
                'access': self.access_token,
            }

            if not auth_httponly:
                data['refresh'] = self.refresh_token
            else:
                # Wasnt sure if the serializer needed this
                data['refresh'] = ''

正如你所看到的最后一句话，它设置为空字符串，当我将其更改为self.refresh_token时，它确实工作了，这是他们的问题，意味着dj-rest-auth包中的错误，还是有其他解决方案？如果这是一个bug，我该如何解决这个问题？

我错误地理解了httponly刷新令牌。经过更多的研究，这就是刷新令牌的工作方式。存储和发送是自动进行的。
当使用HttpOnly cookie作为刷新令牌时，您不会直接从前端访问刷新令牌。相反，浏览器会自动将其与每个向同一域发出的HTTP请求一起发送。下面是如何使用这样的设置：
登录名：
当用户登录时，服务器在HTTP响应中将刷新令牌设置为HttpOnly cookie。前端无法访问此Cookie，但浏览器会存储它。如果您在登录期间还获得了访问令牌（未存储为HttpOnly cookie），则前端可以将其存储在内存中（或其他安全性较低的客户端存储，如localStorage或sessionStorage，如果需要）。使用访问令牌：
为了访问受保护的资源，前端发送带有访问令牌的请求（通常在Authorization头中）。如果访问令牌有效，则服务器处理请求。访问令牌过期和刷新：
当访问令牌过期并且对受保护资源的请求因此失败时，前端会识别此过期（通常通过401 Unauthorized响应）。然后，前端向服务器上的令牌刷新端点发送请求。由于刷新令牌存储为HttpOnly cookie，因此它会自动与此请求一起发送。服务器检查刷新令牌，如果它有效，就发出一个新的访问令牌，并在响应中将其发回。然后，前端使用新的访问令牌重试原始请求。注销：
在注销时，前端向注销端点发送请求。然后服务器会使刷新令牌无效，并发送一个响应，告诉浏览器删除刷新令牌cookie。
