**FastAPI** позаботится о том, чтобы считать эти данные из нужного места, а не из JSON.

/// note | Технические детали

Данные из форм обычно кодируются с использованием "media type" `application/x-www-form-urlencoded` когда он не включает файлы.

Но когда форма включает файлы, она кодируется как multipart/form-data. Если вы используете `File`, **FastAPI** будет знать, что ему нужно получить файлы из нужной части тела.

### Tags with Enums { #tags-with-enums }

If you have a big application, you might end up accumulating **several tags**, and you would want to make sure you always use the **same tag** for related *path operations*.

In these cases, it could make sense to store the tags in an `Enum`.

## Pin your `fastapi` version { #pin-your-fastapi-version }

The first thing you should do is to "pin" the version of **FastAPI** you are using to the specific latest version that you know works correctly for your application.

For example, let's say you are using version `0.112.0` in your app.

If you use a `requirements.txt` file you could specify the version with:

```txt
fastapi[standard]==0.112.0
```

Você pode declarar vários parâmetros `File` e `Form` em uma *operação de caminho*, mas não é possível declarar campos `Body` para receber como JSON, pois a requisição terá o corpo codificado usando `multipart/form-data` ao invés de `application/json`.

Isso não é uma limitação do **FastAPI** , é parte do protocolo HTTP.
