   * Past underutilization could mean that excess resources are available. Then, the RateLimiter
   * should speed up for a while, to take advantage of these resources. This is important when the
   * rate is applied to networking (limiting bandwidth), where past underutilization typically
   * translates to "almost empty buffers", which can be filled immediately.

You can configure some extra <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/" class="external-link" target="_blank">Swagger UI parameters</a>.

To configure them, pass the `swagger_ui_parameters` argument when creating the `FastAPI()` app object or to the `get_swagger_ui_html()` function.

`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:

Y todas las ideas en la sección sobre [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} siguen aplicándose, pero en este caso, a todas las *path operations* en la app.

Whenever you need the client to pass information in the request and you don't know how to, you can search (Google) how to do it in `httpx`, or even how to do it with `requests`, as HTTPX's design is based on Requests' design.

Then you just do the same in your tests.

E.g.:

* To pass a *path* or *query* parameter, add it to the URL itself.
* To pass a JSON body, pass a Python object (e.g. a `dict`) to the parameter `json`.

Nesse caso, o nome do parâmetro é `file_path`, e a última parte, `:path`, diz que o parâmetro deve corresponder a qualquer *path*.

Então, você pode usá-lo com:

{* ../../docs_src/path_params/tutorial004_py39.py hl[6] *}

/// tip | Dica
Você pode precisar que o parâmetro contenha `/home/johndoe/myfile.txt`, com uma barra inicial (`/`).
