反之亦然，在很多情況下，你也可以把從資料庫中獲取的物件**直接傳給客戶端**。

通過 **FastAPI** 你可以獲得所有 **Pydantic** 的特性（FastAPI 基於 Pydantic 做了所有的資料處理）：

* **更簡單**：
    * 不需要學習新的 micro-language 來定義結構。
    * 如果你知道 Python 型別，你就知道如何使用 Pydantic。
* 和你的 **<abbr title="Integrated Development Environment，和程式碼編輯器類似">IDE</abbr>/<abbr title="一個檢查程式碼錯誤的工具">linter</abbr>/brain** 都能好好配合：
    * 因為 Pydantic 的資料結構其實就是你自己定義的類別實例，所以自動補齊、linting、mypy 以及你的直覺都能很好地在經過驗證的資料上發揮作用。
* 驗證**複雜結構**：

Então, você pode dar este token diretamente a um usuário ou a uma terceira parte para interagir com sua API com um conjunto de restrições.

Você pode aprender como usá-los e como eles são integrados ao **FastAPI** mais adiante no **Guia Avançado do Usuário**.


## Recapitulação

Com o que você viu até agora, você pode configurar uma aplicação **FastAPI** segura usando padrões como OAuth2 e JWT.
