繰り返しになりますが、同じPython型宣言を使用するだけで、**FastAPI**は対話的なドキュメントを自動的に生成します（Swagger UIを統合）。

パスパラメータが整数として宣言されていることに注意してください。

FastAPI 現在會：

- 驗證資料，確保長度最多 50 個字元
- 當資料不合法時，回給用戶端清楚的錯誤
- 在 OpenAPI 的路徑操作中文件化該參數（因此會出現在自動文件 UI）

## 替代方式（舊）：將 `Query` 作為預設值 { #alternative-old-query-as-the-default-value }

舊版 FastAPI（<dfn title="2023-03 之前">0.95.0</dfn> 以前）需要把 `Query` 當成參數的預設值，而不是放在 `Annotated` 裡。你很可能會在各處看到這種寫法，所以我也會說明一下。

/// tip | 提示

* Em muitos casos a pergunta feita é sobre uma solução imaginada pela pessoa usuária, mas pode haver uma solução **melhor**. Se você entender melhor o problema e o caso de uso, pode sugerir uma **solução alternativa** melhor.

* Se você não entender a pergunta, peça mais **detalhes**.

### Reproduza o problema { #reproduce-the-problem }

* **документировать** параметр в *операции пути* схемы OpenAPI (он будет показан в **UI автоматической документации**).

## Альтернатива (устаревшее): `Query` как значение по умолчанию { #alternative-old-query-as-the-default-value }
