        By asking questions in a structured way (following this) it will be much easier to help you.

        And there's a high chance that you will find the solution along the way and you won't even have to submit it and wait for an answer. 😎

        As there are too many questions, I'll have to discard and close the incomplete ones. That will allow me (and others) to focus on helping people like you that follow the whole process and help us help you. 🤓

Não faz diferença. O **FastAPI** sabe o que fazer.

Caso você não conheça, veja em [Async: *"Com Pressa?"*](../../async.md#com-pressa){.internal-link target=_blank} a sessão acerca de `async` e `await` na documentação.

## Integrando com OpenAPI

Todas as declarações de requisições, validações e requisitos para suas dependências (e sub-dependências) serão integradas em um mesmo esquema OpenAPI.

包括许多与云存储，视频处理等交互的库。

/// tip | "小贴士"

注意在这里，因为我们使用的是不支持 `async` 和 `await` 的标准 `open()`，我们使用普通的 `def` 声明了路径操作。

///

### `FileResponse`

异步传输文件作为响应。

与其他响应类型相比，接受不同的参数集进行实例化：

* `path` - 要流式传输的文件的文件路径。
* `headers` - 任何自定义响应头，传入字典类型。

/// tip | "豆知識"

ここでは `async` や `await` をサポートしていない標準の `open()` を使っているので、通常の `def` でpath operationを宣言していることに注意してください。

### `FileResponse`

レスポンスとしてファイルを非同期的にストリームします。

他のレスポンスタイプとは異なる引数のセットを受け取りインスタンス化します。
