django drf 自定义jwt用户验证逻辑

新建Backend类

from django.contrib.auth.backends import ModelBackend
from django.shortcuts import render
 
from django.http import HttpResponse
# Create your views here.
 
from django.contrib.auth import get_user_model
from django.db.models import Q
 
User = get_user_model()  # 须在settings里配置AUTH_USER_MODEL = 'users.UserProfile'
 
class CumstomBackend(ModelBackend):
    def authenticate(self, request, username=None, password=None, **kwargs):
        try:
            user = User.objects.get(Q(username=username)|Q(mobile=username))
            if user.check_password(password):
                return user
        except Exception as e:
            return None

配置settings

AUTH_USER_MODEL = 'users.UserProfile'
AUTHENTICATION_BACKENDS=(
    'users.views.CumstomBackend',
)
