如何将自定义Django身份验证与其rest TokenAuthentication一起使用

from django.contrib.auth.backends import BaseBackend
from django.contrib.auth import get_user_model

User = get_user_model()

class CustomAuthBackend(BaseBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        # 自定义身份验证逻辑
        # 验证成功返回用户对象，否则返回None

AUTHENTICATION_BACKENDS = [
    'path.to.CustomAuthBackend',
    'django.contrib.auth.backends.ModelBackend',  # 默认的认证后端
]

from rest_framework.authentication import TokenAuthentication

class MyView(APIView):
    authentication_classes = [TokenAuthentication]
    
    def get(self, request, format=None):
        # 处理GET请求的逻辑

from django.db import models
from django.contrib.auth.models import AbstractUser
from rest_framework.authtoken.models import Token

class User(AbstractUser):
    # 自定义用户模型

class CustomAuthBackend(BaseBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            user = User.objects.get(username=username)
            if user.check_password(password):
                token, _ = Token.objects.get_or_create(user=user)
                return user
        except User.DoesNotExist:
            return None
