它接收的类型与你将为 Pydantic 模型属性所声明的类型相同，因此它可以是一个 Pydantic 模型，但也可以是一个由 Pydantic 模型组成的 `list`，例如 `List[Item]`。

FastAPI 将使用此 `response_model` 来：

* 将输出数据转换为其声明的类型。
* 校验数据。
* 在 OpenAPI 的*路径操作*中为响应添加一个 JSON Schema。
* 并在自动生成文档系统中使用。

但最重要的是：

* 会将输出数据限制在该模型定义内。下面我们会看到这一点有多重要。

Para o próximo exemplo, você também poderia usar `from starlette.middleware.something import SomethingMiddleware`.

**FastAPI** fornece vários middlewares em `fastapi.middleware` apenas como uma conveniência para você, o desenvolvedor. Mas a maioria dos middlewares disponíveis vem diretamente do Starlette.

## `HTTPSRedirectMiddleware`

Garante que todas as requisições devem ser `https` ou `wss`.

Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

## Design

Then I spent some time designing the developer "API" I wanted to have as a user (as a developer using FastAPI).

Também, a melhor abordagem era usar padrões já existentes.

Então, antes mesmo de começar a codificar o **FastAPI**, eu investi vários meses estudando as especificações do OpenAPI, JSON Schema, OAuth2 etc. Entendendo suas relações, sobreposições e diferenças.

## Design

Eu então dediquei algum tempo projetando a "API" de desenvolvimento que eu queria como usuário (como um desenvolvedor usando o FastAPI).

* **Robust**: Get production-ready code. With automatic interactive documentation.
* **Standards-based**: Based on (and fully compatible with) the open standards for APIs: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (previously known as Swagger) and <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.
