一、settings中配置

AUTHENTICATION_BACKENDS = (
    'users.views.CustomBackend',
)

二、users/views.py

# users.views.py

from django.contrib.auth.backends import ModelBackend
from django.contrib.auth import get_user_model
from django.db.models import Q

User = get_user_model()

class CustomBackend(ModelBackend):
    """
    自定义用户验证
    """
    def authenticate(self, username=None, password=None, **kwargs):
        try:
            #用户名和手机都能登录
            user = User.objects.get(
                Q(username=username) | Q(mobile=username))
            if user.check_password(password):
                return user
        except Exception as e:
            return None

三、JWT有效时间设置

settings中配置

import datetime
#有效期限
JWT_AUTH = {
    'JWT_EXPIRATION_DELTA': datetime.timedelta(days=7),    #也可以设置seconds=20
    'JWT_AUTH_HEADER_PREFIX': 'JWT',                       #JWT跟前端保持一致，比如“token”这里设置成JWT
}
