/// tip | 豆知識

各オペレーション (HTTPメソッド)は自由に使用できます。

**FastAPI**は特定の意味づけを強制しません。

ここでの情報は、要件ではなくガイドラインとして提示されます。

例えば、GraphQLを使用する場合、通常は`POST`オペレーションのみを使用してすべてのアクションを実行します。

### Step 4: **path operation 関数**を定義 { #step-4-define-the-path-operation-function }

以下は「**path operation 関数**」です:

* **パス**: は`/`です。

Cela vous permettrait d’avoir un système d’autorisations plus fin, conforme au standard OAuth2, intégré à votre application OpenAPI (et à la documentation de l’API).

OAuth2 avec scopes est le mécanisme utilisé par de nombreux grands fournisseurs d’authentification, comme Facebook, Google, GitHub, Microsoft, X (Twitter), etc. Ils l’utilisent pour fournir des permissions spécifiques aux utilisateurs et aux applications.

      // But in gcd(a - b, b), a - b is even and b is odd, so we can divide out powers of two.

      // We bend over backwards to avoid branching, adapting a technique from
      // http://graphics.stanford.edu/~seander/bithacks.html#IntegerMinOrMax

      int delta = a - b; // can't overflow, since a and b are nonnegative

      int minDeltaOrZero = delta & (delta >> (Integer.SIZE - 1));

* Des techniques plus avancées (mais tout aussi faciles) pour déclarer des **modèles JSON profondément imbriqués** (grâce à Pydantic).
* Intégration **GraphQL** avec [Strawberry](https://strawberry.rocks) et d'autres bibliothèques.
* De nombreuses fonctionnalités supplémentaires (grâce à Starlette) comme :
    * **WebSockets**

E como você pode ter paralelismo e assincronicidade ao mesmo tempo, você tem uma maior performance do que a maioria dos frameworks NodeJS testados e lado a lado com Go, que é uma linguagem compilada, mais próxima ao C [(tudo graças ao Starlette)](https://www.techempower.com/benchmarks/#section=data-r17&hw=ph&test=query&l=zijmkf-1).

### Concorrência é melhor que paralelismo? { #is-concurrency-better-than-parallelism }

* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth.
* More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic).
* **GraphQL** integration with [Strawberry](https://strawberry.rocks) and other libraries.
* Many extra features (thanks to Starlette) as:
    * **WebSockets**
    * extremely easy tests based on HTTPX and `pytest`
    * **CORS**

* 安全與驗證，包含支援 **OAuth2** 搭配 **JWT tokens** 與 **HTTP Basic** 驗證。
* 宣告**深度巢狀 JSON 模型**的進階（但同樣簡單）技巧（感謝 Pydantic）。
* 與 [Strawberry](https://strawberry.rocks) 及其他函式庫的 **GraphQL** 整合。
* 許多額外功能（感謝 Starlette），例如：
    * **WebSockets**
    * 基於 HTTPX 與 `pytest` 的極其簡單的測試
    * **CORS**
    * **Cookie Sessions**
    * ...以及更多。
