## Proxy with a stripped path prefix

Having a proxy with a stripped path prefix, in this case, means that you could declare a path at `/app` in your code, but then, you add a layer on top (the proxy) that would put your **FastAPI** application under a path like `/api/v1`.

In this case, the original path `/app` would actually be served at `/api/v1/app`.

Even though all your code is written assuming there's just `/app`.

Sie können das Experiment mit einem abgetrennten Pfadpräfix ganz einfach lokal ausführen, indem Sie <a href="https://docs.traefik.io/" class="external-link" target="_blank">Traefik</a> verwenden.

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">Laden Sie Traefik herunter</a>, es ist eine einzelne Binärdatei, Sie können die komprimierte Datei extrahieren und sie direkt vom Terminal aus ausführen.

但输入**官方**链接 `/api/v1/docs`，并使用端口 `9999` 访问 API 文档，就能正常运行了！🎉
