在我的django-rest项目中，我尝试使用knox进行登录认证
但在我看来，即使用户存在并且我正确提供了用户名和密码，serializer.is_valid（raise_exception=True）也总是返回False
我检查AuthKnoxSerializer的验证方法

class AuthTokenSerializer(serializers.Serializer):
...
   def validate(self, attrs):
        username = attrs.get('username')
        password = attrs.get('password')

        if username and password:
            user = authenticate(request=self.context.get('request'),
                                username=username, password=password)

字符串
当我在Django shell中检查autenticate是否正常工作时，
在Django shell中

>>>from django.contrib.auth import authenticate
>>>from django.contrib.auth import get_user_model
>>>get_user_model().objects.get(username="CIEMSA",password="225236Cm.")
<MyUser: CIEMSA>
>>>print(authenticate(username="CIEMSA", password="225236Cm."))
None

任何想法，为什么不工作？
