尝试覆盖TokenObtainSerializer的validate（）方法，如下所示：

serializers.py

class CustomTokenObtainPairSerializer(TokenObtainSerailizer):
    def validate():
        ...
        authenticate_kwargs = {
            self.username_field: attrs[self.username_field],
            'password': attrs['password'],
        }
        try:
            authenticate_kwargs['request'] = self.context['request']
        except KeyError:
            pass
        self.user = authenticate(**authenticate_kwargs)
        print(self.user)
        if self.user is None or not self.user.is_active:
            self.error_messages['no_active_account'] = _(
                'No active account found with the given credentials') # --> Change this error message for what you want to replace this with.
            raise exceptions.AuthenticationFailed(
                self.error_messages['no_active_account'],
                'no_active_account',
            )
        return super().validate(attrs)

现在更新您的序列化器类，以使用自定义序列化器作为：

class MyTokenObtainPairSerializer(CustomTokenObtainPairSerailizer):
    pass
