* Importa `HTTPBasic` y `HTTPBasicCredentials`.
* Crea un "esquema de `security`" usando `HTTPBasic`.
* Usa ese `security` con una dependencia en tu *path operation*.
* Devuelve un objeto de tipo `HTTPBasicCredentials`:
  * Contiene el `username` y `password` enviados.

/// tip | Astuce

Comme Pydantic le sérialisera du côté **Rust**, vous obtiendrez une **performance** bien supérieure que si vous ne déclarez pas de type de retour.

### Fonctions de chemin d'accès non async { #non-async-path-operation-functions }

Vous pouvez aussi utiliser des fonctions `def` normales (sans `async`), et utiliser `yield` de la même façon.

FastAPI s’assure qu’elles s’exécutent correctement pour ne pas bloquer la boucle d’événements.

# 直接回傳 Response { #return-a-response-directly }

當你建立一個 **FastAPI** 的路徑操作 (path operation) 時，通常可以從中回傳任何資料：`dict`、`list`、Pydantic 模型、資料庫模型等。

如果你宣告了 [回應模型](../tutorial/response-model.md)，FastAPI 會用 Pydantic 將資料序列化為 JSON。

如果你沒有宣告回應模型，FastAPI 會使用在[JSON 相容編碼器](../tutorial/encoder.md)中說明的 `jsonable_encoder`，並把它放進 `JSONResponse`。

但你也可以直接從路徑操作回傳 `JSONResponse`。

### [Uvicorn](https://www.uvicorn.dev/) { #uvicorn }

Uvicorn is a lightning-fast ASGI server, built on uvloop and httptools.

It is not a web framework, but a server. For example, it doesn't provide tools for routing by paths. That's something that a framework like Starlette (or **FastAPI**) would provide on top.

It is the recommended server for Starlette and **FastAPI**.

/// check | **FastAPI** recommends it as

            return projectRootDir.relativePath(mainApiChangesJsonFile)

            return "<PATHS TO API CHANGES JSON NOT PROVIDED>"
        }
    }
