Вы можете легко поэкспериментировать локально с урезанным префиксом пути, используя <a href="https://docs.traefik.io/" class="external-link" target="_blank">Traefik</a>.

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">Скачайте Traefik</a> — это один бинарный файл; распакуйте архив и запустите его прямо из терминала.

Затем создайте файл `traefik.toml` со следующим содержимым:

You can easily run the experiment locally with a stripped path prefix using <a href="https://docs.traefik.io/" class="external-link" target="_blank">Traefik</a>.

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">Download Traefik</a>, it's a single binary, you can extract the compressed file and run it directly from the terminal.

Then create a file `traefik.toml` with:

                    (fields) defined in the `response_model`. If you returned an object

                    not include that field, the JSON sent to the client would not have
                    that `password`.
