The string will be checked to be a valid URL, and documented in JSON Schema / OpenAPI as such.

## Attributes with lists of submodels { #attributes-with-lists-of-submodels }

You can also use Pydantic models as subtypes of `list`, `set`, etc.:

Erzwingt, dass alle eingehenden <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Requests</abbr> entweder `https` oder `wss` sein müssen.

Alle eingehenden Requests an `http` oder `ws` werden stattdessen an das sichere Schema umgeleitet.

* Agregar un **JSON Schema** para el response, en la *path operation* de OpenAPI.
    * Esto será utilizado por la **documentación automática**.
    * También será utilizado por herramientas de generación automática de código de cliente.

Die Datenklasse wird automatisch in eine Pydantic-Datenklasse konvertiert.

Auf diese Weise wird deren Schema in der Benutzeroberfläche der API-Dokumentation angezeigt:

## Datenklassen in verschachtelten Datenstrukturen { #dataclasses-in-nested-data-structures }

You can also use `dataclasses` in the `response_model` parameter:

{* ../../docs_src/dataclasses_/tutorial002_py310.py hl[1,6:12,18] *}

The dataclass will be automatically converted to a Pydantic dataclass.

This way, its schema will show up in the API docs user interface:

## Dataclasses in Nested Data Structures { #dataclasses-in-nested-data-structures }

「模式」的定义包括你的 API 路径，以及它们可能使用的参数等等。

#### 数据「模式」

「模式」这个术语也可能指的是某些数据比如 JSON 的结构。

在这种情况下，它可以表示 JSON 的属性及其具有的数据类型，等等。

#### OpenAPI 和 JSON Schema

OpenAPI 为你的 API 定义 API 模式。该模式中包含了你的 API 发送和接收的数据的定义（或称为「模式」），这些定义通过 JSON 数据模式标准 **JSON Schema** 所生成。

#### 查看 `openapi.json`

如果你对原始的 OpenAPI 模式长什么样子感到好奇，FastAPI 自动生成了包含所有 API 描述的 JSON（模式）。
