```

... **FastAPI**가 실제로 어떤 것이 의존성인지 알기 위해서 사용하는 방법입니다.
FastAPI는 선언된 매개변수들을 추출할 것이고 실제로 이 변수들을 호출할 것입니다.

---

이 경우에, 첫번째 `CommonQueryParams` 변수를 보면:

```Python
commons: CommonQueryParams ...
```

... **FastAPI**는 `CommonQueryParams` 변수에 어떠한 특별한 의미도 부여하지 않습니다. FastAPI는 이 변수를 데이터 변환, 검증 등에 활용하지 않습니다. (활용하려면 `= Depends(CommonQueryParams)`를 사용해야 합니다.)

사실 아래와 같이 작성해도 무관합니다:

docs/zh/docs/tutorial/background-tasks.md

它被直接导入/包含到FastAPI以便你可以从 `fastapi` 导入，并避免意外从 `starlette.background` 导入备用的 `BackgroundTask` (后面没有 `s`)。

通过仅使用 `BackgroundTasks` (而不是 `BackgroundTask`)，使得能将它作为 *路径操作函数* 的参数 ，并让**FastAPI**为您处理其余部分, 就像直接使用 `Request` 对象。

在FastAPI中仍然可以单独使用 `BackgroundTask`，但您必须在代码中创建对象，并返回包含它的Starlette `Response`。

docs/en/docs/how-to/configure-swagger-ui.md

To configure them, pass the `swagger_ui_parameters` argument when creating the `FastAPI()` app object or to the `get_swagger_ui_html()` function.

`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.

FastAPI converts the configurations to **JSON** to make them compatible with JavaScript, as that's what Swagger UI needs.

docs/zh/docs/tutorial/security/oauth2-jwt.md

**高级用户指南**中将介绍如何使用 `scopes`，及如何把 `scopes` 集成至 **FastAPI**。

## 小结

至此，您可以使用 OAuth2 和 JWT 等标准配置安全的 **FastAPI** 应用。

几乎在所有框架中，处理安全问题很快都会变得非常复杂。

有些包为了简化安全流，不得不在数据模型、数据库和功能上做出妥协。而有些过于简化的软件包其实存在了安全隐患。

---

**FastAPI** 不向任何数据库、数据模型或工具做妥协。

开发者可以灵活选择最适合项目的安全机制。

还可以直接使用 `passlib` 和 `PyJWT` 等维护良好、使用广泛的包，这是因为 **FastAPI** 不需要任何复杂机制，就能集成外部的包。

而且，**FastAPI** 还提供了一些工具，在不影响灵活、稳定和安全的前提下，尽可能地简化安全机制。
