# Arquivos de Requisição { #request-files }

Você pode definir arquivos para serem enviados pelo cliente usando `File`.

/// info | Informação

Para receber arquivos enviados, primeiro instale [`python-multipart`](https://github.com/Kludex/python-multipart).

Garanta que você criou um [ambiente virtual](../virtual-environments.md), o ativou e então o instalou, por exemplo:

```console
$ pip install python-multipart
```

# 請求中的檔案 { #request-files }

你可以使用 `File` 定義由用戶端上傳的檔案。

/// info

若要接收上傳的檔案，請先安裝 [`python-multipart`](https://github.com/Kludex/python-multipart)。

請先建立並啟用一個[虛擬環境](../virtual-environments.md)，然後安裝，例如：

```console
$ pip install python-multipart
```

因為上傳的檔案是以「表單資料」送出的。

## 匯入 `File` { #import-file }

從 `fastapi` 匯入 `File` 與 `UploadFile`：

Pour déclarer des fichiers dans le corps de la requête, vous devez utiliser `File`, sinon les paramètres seraient interprétés comme des paramètres de requête ou des paramètres de corps (JSON).

///

Les fichiers seront téléversés en « données de formulaire ».

# Archivos de Request { #request-files }

Puedes definir archivos que serán subidos por el cliente utilizando `File`.

/// info | Información

Para recibir archivos subidos, primero instala [`python-multipart`](https://github.com/Kludex/python-multipart).

Asegúrate de crear un [entorno virtual](../virtual-environments.md), activarlo y luego instalarlo, por ejemplo:

```console
$ pip install python-multipart
