/// note | Hinweis

Beachten Sie, dass Sie die `JSONResponse` direkt zurückgeben müssen.

///

/// info | Info

Der `model`-Schlüssel ist nicht Teil von OpenAPI.

**FastAPI** nimmt das Pydantic-Modell von dort, generiert das JSON-Schema und fügt es an der richtigen Stelle ein.

Die richtige Stelle ist:

# Um modelo do Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Que então pode ser usado como:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)
```

/// info | Informação

`**second_user_data` quer dizer:

本例把 `item_id` 的类型声明为 `int`。

/// check | 检查

类型声明将为函数提供错误检查、代码补全等编辑器支持。

///

## 数据<abbr title="也称为：序列化、解析">转换</abbr>

运行示例并访问 <a href="http://127.0.0.1:8000/items/3" class="external-link" target="_blank">http://127.0.0.1:8000/items/3</a>，返回的响应如下：

```JSON
{"item_id":3}
```

/// check | 检查

注意，函数接收并返回的值是 `3`（ `int`），不是 `"3"`（`str`）。

Puedes especificar la descripción del response con el parámetro `response_description`:

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[19] *}

/// info | Información

Ten en cuenta que `response_description` se refiere específicamente al response, mientras que `description` se refiere a la *path operation* en general.

///

/// check | Revisa

## Descrição da resposta { #response-description }

Você pode especificar a descrição da resposta com o parâmetro `response_description`:

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[19] *}

/// info | Informação

Note que `response_description` se refere especificamente à resposta, a `description` se refere à *operação de rota* em geral.

# Альтернативы, источники вдохновения и сравнения { #alternatives-inspiration-and-comparisons }

Что вдохновило **FastAPI**, сравнение с альтернативами и чему он у них научился.

## Введение { #intro }

**FastAPI** не существовал бы без предыдущих работ других людей.

Было создано множество инструментов, которые вдохновили на его появление.

This requires installing `orjson` for example with `pip install orjson`.

### `UJSONResponse` { #ujsonresponse }
