Böylece `/openapi.json`, `/docs` veya `/redoc` URL'lerine giderseniz, aşağıdaki gibi bir `404 Not Found` hatası alırsınız:

{* ../../docs_src/events/tutorial002_py310.py hl[6] *}

Aqui, a função de manipulador do evento `shutdown` escreverá uma linha de texto `"Application shutdown"` no arquivo `log.txt`.

/// info | Informação

Na função `open()`, o `mode="a"` significa "acrescentar", então a linha será adicionada depois do que já estiver naquele arquivo, sem sobrescrever o conteúdo anterior.

/// info | 정보

`model` 키는 OpenAPI의 일부가 아닙니다.

**FastAPI**는 여기에서 Pydantic 모델을 가져와 JSON Schema를 생성하고 올바른 위치에 넣습니다.

올바른 위치는 다음과 같습니다:

* 값으로 또 다른 JSON 객체(`dict`)를 가지는 `content` 키 안에:

# 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。
