## Múltiplos parâmetros de corpo { #multiple-body-parameters }

No exemplo anterior, as *operações de rota* esperariam um JSON no corpo contendo os atributos de um `Item`, exemplo:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

{* ../../docs_src/response_model/tutorial001_01_py310.py hl[16,21] *}

由於這會在 Rust 端發生，效能會比用一般的 Python 與 `JSONResponse` 類別來完成好得多。

當使用 `response_model` 或回傳型別時，FastAPI 不會使用 `jsonable_encoder` 來轉換資料（那會較慢），也不會使用 `JSONResponse` 類別。

相反地，它會取用用回應模型（或回傳型別）透過 Pydantic 產生的 JSON 位元組，並直接回傳具備正確 JSON 媒體型別（`application/json`）的 `Response`。

## 注意事項 { #notes }

Bir sonraki bölümde, password hashing ve <abbr title="JSON Web Tokens">JWT</abbr> token’ları ile gerçekten güvenli bir implementasyon göreceksiniz.

Ama şimdilik ihtiyacımız olan spesifik detaylara odaklanalım.

/// tip | İpucu

Spesifikasyona göre, bu örnekteki gibi `access_token` ve `token_type` içeren bir JSON döndürmelisiniz.
