### ドキュメントの確認 { #check-the-docs }

ここでドキュメントを確認すると、追加したメタデータがすべて表示されます:

<img src="/img/tutorial/metadata/image02.png">

### タグの順番 { #order-of-tags }

タグのメタデータ辞書の順序は、ドキュメントUIに表示される順序の定義にもなります。

たとえば、`users` はアルファベット順では `items` の後に続きますが、リストの最初の辞書としてメタデータを追加したため、それより前に表示されます。

## OpenAPI URL { #openapi-url }

デフォルトでは、OpenAPIスキーマは `/openapi.json` で提供されます。

				// number of items than number of online disks.
				inconsistent++
				continue
			}
			if meta.Erasure.Distribution[i] != meta.Erasure.Index {
				// Mismatch indexes with distribution order
				inconsistent++
			}
		}
	}

	erasureDistributionReliable := inconsistent <= len(partsMetadata)/2

	metaErrs := make([]error, len(errs))

	for i := range onlineDisks {

Você pode usar as mesmas declarações de tipo com `str`, `float`, `bool` e muitos outros tipos de dados complexos.

Vários deles são explorados nos próximos capítulos do tutorial.

## A ordem importa { #order-matters }

Ao criar *operações de rota*, você pode encontrar situações em que tem um path fixo.

Como `/users/me`, digamos que seja para obter dados sobre o usuário atual.

## Pydantic { #pydantic }

FastAPI 充分地利用了 [Pydantic](https://docs.pydantic.dev/) 的优势，用它在后台校验数据。众所周知，Pydantic 擅长的就是数据校验。

同样，`str`、`float`、`bool` 以及很多复合数据类型都可以使用类型声明。

接下来的章节会介绍其中的好几种。

## 顺序很重要 { #order-matters }

有时，*路径操作*中的路径是写死的。

比如要使用 `/users/me` 获取当前用户的数据。

然后还要使用 `/users/{user_id}`，通过用户 ID 获取指定用户的数据。

由于*路径操作*是按顺序依次运行的，因此，一定要在 `/users/{user_id}` 之前声明 `/users/me` ：

  private val taskRunner = builder.taskRunner

  /** Asynchronously writes frames to the outgoing socket. */
  private val writerQueue = taskRunner.newQueue()

  /** Ensures push promise callbacks events are sent in order per stream. */
  private val pushQueue = taskRunner.newQueue()

  /** Notifies the listener of settings changes. */
  private val settingsListenerQueue = taskRunner.newQueue()
