### Faça o deploy da sua aplicação (opcional) { #deploy-your-app-optional }

Você pode, opcionalmente, fazer o deploy da sua aplicação FastAPI na [FastAPI Cloud](https://fastapicloud.com); acesse e entre na lista de espera, se ainda não entrou. 🚀

* `tags: List[str] = []` için default, boş bir list’tir: `[]`.

Ancak gerçekte kaydedilmedilerse, bunları sonuçtan çıkarmak isteyebilirsiniz.

Örneğin NoSQL veritabanında çok sayıda optional attribute içeren modelleriniz varsa, default değerlerle dolu çok uzun JSON response’ları göndermek istemeyebilirsiniz.

### `response_model_exclude_unset` parametresini kullanın { #use-the-response-model-exclude-unset-parameter }

// ScanLines is a split function for a [Scanner] that returns each line of

// The last non-empty line of input will be returned even if it has no
// newline.

## 任意のファイルアップロード { #optional-file-upload }

標準の型アノテーションを使い、デフォルト値を `None` に設定することで、ファイルを任意にできます:

{* ../../docs_src/request_files/tutorial001_02_an_py310.py hl[9,17] *}

## 追加メタデータつきの `UploadFile` { #uploadfile-with-additional-metadata }

但这样每次调用 `fastapi` 命令时都需要记得传入正确的路径。

另外，其他工具可能无法找到它，例如 [VS Code 扩展](../editor-support.md) 或 [FastAPI Cloud](https://fastapicloud.com)，因此推荐在 `pyproject.toml` 中使用 `entrypoint`。

### 部署你的应用（可选） { #deploy-your-app-optional }

你可以选择将 FastAPI 应用部署到 [FastAPI Cloud](https://fastapicloud.com)，如果还没有，先去加入候补名单。🚀

如果你已经拥有 **FastAPI Cloud** 账户（我们从候补名单邀请了你 😉），你可以用一条命令部署应用。

部署前，先确保已登录：
