# Arquivos de Requisição

Você pode definir arquivos para serem enviados para o cliente utilizando `File`.

/// info

Para receber arquivos compartilhados, primeiro  instale <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

E.g. `pip install python-multipart`.

Isso se deve por que arquivos enviados são enviados como "dados de formulário".

## Importe `File`

  //   by the 'containerName' field) is not in the set of specified values.

Es gibt dutzende Alternativen, die alle auf OpenAPI basieren. Sie können jede dieser Alternativen problemlos zu Ihrer mit **FastAPI** erstellten Anwendung hinzufügen.

Ebenfalls können Sie es verwenden, um automatisch Code für Clients zu generieren, die mit Ihrer API kommunizieren. Zum Beispiel für Frontend-, Mobile- oder IoT-Anwendungen.

## Rückblick, Schritt für Schritt

### Schritt 1: Importieren von `FastAPI`

```Python hl_lines="1"

* Wsparcie dla **WebSocket**.
* <abbr title='Zadania wykonywane w tle, bez zatrzymywania żądań, w tym samym procesie. Po angielsku: In-process background tasks'>Zadania w tle</abbr>.
* Eventy startup i shutdown.
* Klient testowy zbudowany na bazie biblioteki `requests`.
* **CORS**, GZip, pliki statyczne, streamy.
* Obsługa **sesji i ciasteczek**.
* 100% pokrycie testami.
* 100% adnotacji typów.

## Cechy Pydantic

Na verdade é comum utilizar Requests *dentro* de uma aplicação FastAPI.

Ainda assim, FastAPI pegou alguma inspiração do Requests.

**Requests** é uma biblioteca para interagir com APIs (como um cliente), enquanto **FastAPI** é uma biblioteca para *construir* APIs (como um servidor).

Eles estão, mais ou menos, em pontas opostas, um complementando o outro.

And there are dozens of alternatives, all based on OpenAPI. You could easily add any of those alternatives to your application built with **FastAPI**.

You could also use it to generate code automatically, for clients that communicate with your API. For example, frontend, mobile or IoT applications.
