Você verá sua documentação incluindo uma seção "Callbacks" para sua *operação de rota* que mostra como a *API externa* deveria ser:

Common examples of CPU bound operations are things that require complex math processing.

For example:

* **Audio** or **image processing**.
* **Computer vision**: an image is composed of millions of pixels, each pixel has 3 values / colors, processing that normally requires computing something on those pixels, all at the same time.

Don't worry if some of these items about **containers**, Docker, or Kubernetes don't make a lot of sense yet.

* Update kube-proxy image to be based off of Debian 8.6 base image. ([#39695](https://github.com/kubernetes/kubernetes/pull/39695), [@ixdy](https://github.com/ixdy))

* Update amd64 kube-proxy base image to debian-iptables-amd64:v5 ([#39725](https://github.com/kubernetes/kubernetes/pull/39725), [@ixdy](https://github.com/ixdy))
* Update kube-proxy image to be based off of Debian 8.6 base image. ([#39695](https://github.com/kubernetes/kubernetes/pull/39695), [@ixdy](https://github.com/ixdy))

그러나 자료형을 선언하면 에디터가 매개변수 `commons`로 전달될 것이 무엇인지 알게 되고, 이를 통해 코드 완성, 자료형 확인 등에 도움이 될 수 있으므로 권장됩니다.

## 코드 단축

그러나 여기 `CommonQueryParams`를 두 번이나 작성하는, 코드 반복이 있다는 것을 알 수 있습니다:

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

现在，使用 Uvicorn 启动应用，打开 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs。</a>

就能看到文档的*路径操作*已经包含了**回调**的内容以及*外部 API*：

## Сокращение

Но вы видите, что здесь мы имеем некоторое повторение кода, дважды написав `CommonQueryParams`:
