But FastAPI also supports using [`dataclasses`](https://docs.python.org/3/library/dataclasses.html) the same way:

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

This is still supported thanks to **Pydantic**, as it has [internal support for `dataclasses`](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).

Führen Sie nun den Befehl `fastapi` aus:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Und öffnen Sie die Dokumentation unter [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

You can check it at [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs):

But if we access the docs UI at the "official" URL using the proxy with port `9999`, at `/api/v1/docs`, it works correctly! 🎉

You can check it at [http://127.0.0.1:9999/api/v1/docs](http://127.0.0.1:9999/api/v1/docs):

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

Right as we wanted it. ✔️

    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="GET /items/ Read Items").click()
    page.get_by_role("button", name="Try it out").click()
    # Manually add the screenshot
    page.screenshot(path="docs/en/docs/img/tutorial/header-param-models/image01.png")

    # ---------------------
    context.close()
    browser.close()

    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="POST /login/ Login").click()
    page.get_by_role("button", name="Try it out").click()
    # Manually add the screenshot
    page.screenshot(path="docs/en/docs/img/tutorial/request-form-models/image01.png")

    # ---------------------
    context.close()
    browser.close()

Sonrasında, environment variable `OPENAPI_URL`'i boş string olarak ayarlayarak OpenAPI'yi (UI docs dahil) devre dışı bırakabilirsiniz; örneğin:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Böylece `/openapi.json`, `/docs` veya `/redoc` URL'lerine giderseniz, aşağıdaki gibi bir `404 Not Found` hatası alırsınız:
