Python 在 djangorestframeworksimplejwt 中使用三个字段进行身份验证

我正在DRF中进行自定义身份验证.用户应发送3个字段(phone, email, password).

我一直在遵循这个答案

我用的是源代码https://github.com/jazzband/djangorestframework-simplejwt/blob/master/rest_framework_simplejwt/serializers.py

Problem:对于下面的请求，我收到了一个空响应{}，但预期是令牌或错误消息

{
    "email": "admin1@admin2.ru",
    "password": "admin123456",
    "phone_number": "123132"
}

我的密码:views.py

class CustomTokenObtainPairView(TokenObtainPairView):
    serializer_class = CustomTokenObtainPairSerializer

serializers.py

class CustomTokenObtainPairSerializer(TokenObtainPairSerializer):
    username_field = CustomUser.USERNAME_FIELD

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        self.fields[self.username_field] = serializers.CharField()
        self.fields['password'] = PasswordField()
        self.fields['phone_number'] = serializers.CharField() # authentication requires 3 fields

    def validate(self, attrs):
        authenticate_kwargs = {
            self.username_field: attrs[self.username_field],
            'password': attrs['password'],
            'phone_number': attrs['phone_number']
        }
        try:
            authenticate_kwargs["request"] = self.context["request"]
        except KeyError:
            pass

        self.user = authenticate(**authenticate_kwargs)

        if not api_settings.USER_AUTHENTICATION_RULE(self.user):
            raise exceptions.AuthenticationFailed(
                self.error_messages["no_active_account"],
                "no_active_account",
            )

        return {}
