Les paramètres de requête ne sont pas une partie fixe d'un chemin, ils peuvent être optionnels et avoir des valeurs par défaut.

Dans l'exemple ci-dessus, ils ont des valeurs par défaut qui sont `skip=0` et `limit=10`.

Donc, accéder à l'URL :

```
http://127.0.0.1:8000/items/
```

serait équivalent à accéder à l'URL :

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

Mais si vous accédez à, par exemple :

注意，不能把路由本身（`invoices_callback_router`）传递给 `callback=`，要传递 `invoices_callback_router.routes` 中的 `.routes` 属性。

### 查看文档

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*：

Bu özellik, API'ınızla iletişime geçen kodu geliştirirken ve ayıklarken inanılmaz derecede yararlı olacaktır.

## Dokümantasyon

Ayrıca, tarayıcınızı <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a> adresinde açarsanız, aşağıdaki gibi otomatik ve interaktif bir API dökümantasyonu ile karşılaşırsınız:

  // daemon pod and are supposed to run the daemon pod.
  // More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/
  optional int32 currentNumberScheduled = 1;

  // The number of nodes that are running the daemon pod, but are
  // not supposed to run the daemon pod.
  // More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/
  optional int32 numberMisscheduled = 2;

오류에는 정확히 어느 지점에서 검증을 통과하지 못했는지 명시됩니다.

이는 API와 상호 작용하는 코드를 개발하고 디버깅하는 데 매우 유용합니다.

## 문서화

그리고 브라우저에서 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>를 열면, 다음과 같이 자동 대화식 API 문서를 볼 수 있습니다:

<img src="/img/tutorial/path-params/image01.png">

/// check | "확인"

그저 파이썬 타입 선언을 하기만 하면 **FastAPI**는 자동 대화형 API 문서(Swagger UI)를 제공합니다.
