# Behind a Proxy { #behind-a-proxy }

In many situations, you would use a **proxy** like Traefik or Nginx in front of your FastAPI app.

These proxies could handle HTTPS certificates and other things.

Mas se acessarmos a interface de documentação no URL "oficial" usando o proxy com a porta `9999`, em `/api/v1/docs`, ela funciona corretamente! 🎉

Você pode verificar em <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a>:

Pero si accedemos a la UI de los docs en la URL "oficial" usando el proxy con puerto `9999`, en `/api/v1/docs`, ¡funciona correctamente! 🎉

Puedes verificarlo en <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs</a>:

Justo como queríamos. ✔️

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！🎉

输入 <a href="http://127.0.0.1:9999/api/v1/docs" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/docs 查看文档：</a>

<img src="/img/tutorial/behind-a-proxy/image02.png">

一切正常。 ✔️

Sie können das unter <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a> sehen:

Wenn wir jedoch unter der „offiziellen“ URL, über den Proxy mit Port `9999`, unter `/api/v1/docs`, auf die Dokumentationsoberfläche zugreifen, funktioniert es ordnungsgemäß! 🎉
