# Scopes de OAuth2

Puedes usar scopes de OAuth2 directamente con **FastAPI**, están integrados para funcionar de manera fluida.

Esto te permitiría tener un sistema de permisos más detallado, siguiendo el estándar de OAuth2, integrado en tu aplicación OpenAPI (y la documentación de la API).

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.

    return fromMapEntries(multimap.asMap().entrySet(), valueComparator);

  /**

        byte[] decrypted = ccmContext.decryptMessage(encrypted);
        assertArrayEquals(plaintext, decrypted, "CCM decryption should recover original plaintext");
    }

    @Test
    @DisplayName("Should integrate with SecureKeyManager")
    void testSecureKeyManagerIntegration() throws Exception {
        // Given
        SecureKeyManager keyManager = new SecureKeyManager();
        byte[] testKey = new byte[16];

Up to here, everything would work as normally.

But then, when you open the integrated docs UI (the frontend), it would expect to get the OpenAPI schema at `/openapi.json`, instead of `/api/v1/openapi.json`.
