- 簡單且非常容易使用的 **<abbr title="也被稱為元件、資源、提供者、服務或是注入">依賴注入</abbr>** 系統。
- 安全性和身份驗證，包含提供支援 **OAuth2**、**JWT tokens** 和 **HTTP Basic** 驗證。
- 更進階 (但同樣簡單) 的宣告 **多層次的巢狀 JSON 格式** (感謝 Pydantic)。
- **GraphQL** 與 <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> 以及其他的相關函式庫進行整合。
- 更多其他的功能 (感謝 Starlette) 像是：
    - **WebSockets**
    - 於 HTTPX 和 `pytest` 的非常簡單測試
    - **CORS**

/// 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: **パスオペレーション**を定義

以下は「**パスオペレーション関数**」です:

* **パス**: は`/`です。
* **オペレーション**: は`get`です。
