提供された資格情報でログインできませんdjangoDRF

初めてdjangoREST apiを試したとき、いくつかの認証を行っていますが、このコマンドを実行すると、このエラーが発生します：[curl -X POST -d "username =＆password =" http://127.0.0.1:8000/api/ auth / login /]エラー：{"non_field_errors"：["提供された資格情報でログインできません。"]}

views.py：

        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)
        # We create a token than will be used for future auth
        token = Token.objects.create(user=serializer.instance)
        token_data = {"token": token.key}
        return Response(
            {**serializer.data, **token_data},
