## Importer `Field` { #import-field }

D'abord, vous devez l'importer :

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning | Alertes

Notez que `Field` est importé directement depuis `pydantic`, et non depuis `fastapi` comme le sont les autres (`Query`, `Path`, `Body`, etc.).

///

## Déclarer les attributs du modèle { #declare-model-attributes }

Vous pouvez ensuite utiliser `Field` avec des attributs de modèle :

## Base64 vs Arquivos { #base64-vs-files }

Primeiro, considere se você pode usar [Arquivos na request](../tutorial/request-files.md) para fazer upload de dados binários e [Response personalizada - FileResponse](./custom-response.md#fileresponse--fileresponse-) para enviar dados binários, em vez de codificá-los em JSON.

  public void run() throws Exception {
    Request request = new Request.Builder()

Ahora que hemos visto cómo usar `Path` y `Query`, veamos usos más avanzados de las declaraciones del request body.

## Mezclar `Path`, `Query` y parámetros del cuerpo { #mix-path-query-and-body-parameters }

Primero, por supuesto, puedes mezclar las declaraciones de parámetros de `Path`, `Query` y del request body libremente y **FastAPI** sabrá qué hacer.

If your app needs to receive and send JSON data, but you need to include binary data in it, you can encode it as base64.

## Base64 vs Files { #base64-vs-files }

Consider first if you can use [Request Files](../tutorial/request-files.md) for uploading binary data and [Custom Response - FileResponse](./custom-response.md#fileresponse--fileresponse-) for sending binary data, instead of encoding it in JSON.

Bu örnekte herhangi bir Pydantic model tanımlamadık. Hatta request body JSON olarak <dfn title="bytes gibi düz bir formattan, ör. bytes, Python nesnelerine dönüştürme">ayrıştırılmıyor</dfn>; doğrudan `bytes` olarak okunuyor ve `magic_data_reader()` fonksiyonu bunu bir şekilde parse etmekten sorumlu oluyor.

Buna rağmen, request body için beklenen şemayı tanımlayabiliriz.

The middleware responds to two particular types of HTTP request...

### CORS preflight requests { #cors-preflight-requests }

These are any `OPTIONS` request with `Origin` and `Access-Control-Request-Method` headers.

In this case the middleware will intercept the incoming request and respond with appropriate CORS headers, and either a `200` or `400` response for informational purposes.
