Você também pode usar `from starlette.middleware.cors import CORSMiddleware`.

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

- **জোরালো**: স্বয়ংক্রিয় ভাবে তৈরি ক্রিয়াশীল নির্দেশনা নথি (documentation) সহ উৎপাদন উপযোগি (Production-ready) কোড পাওয়া যায়।
- **মান-ভিত্তিক**: এর ভিত্তি <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (যা পুর্বে Swagger নামে পরিচিত ছিল) এবং <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a> এর আদর্শের মানের ওপর

* **Robosztus**: Production ready kód. Automatikus interaktív dokumentáció val.
* **Szabvány alapú**: Az API-ok nyílt szabványaira alapuló (és azokkal teljesen kompatibilis): <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (korábban Swagger néven ismert) és a <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.

* **Basado en estándares**: Basado y totalmente compatible con los estándares abiertos para APIs: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> (conocido previamente como Swagger) y <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.

XMLを文字列にし、`Response` に含め、それを返します。

```Python hl_lines="1  18"
{!../../docs_src/response_directly/tutorial002.py!}
```

## 備考

`Response` を直接返す場合、バリデーションや、変換 (シリアライズ) や、自動ドキュメントは行われません。

しかし、[Additional Responses in OpenAPI](additional-responses.md){.internal-link target=_blank}に記載されたようにドキュメントを書くこともできます。

Por padrão, teremos o **recarregamento automático** ativo, então o programa irá recarregar o servidor automaticamente toda vez que você fizer mudanças no seu código. Isso usa muitos recursos e pode ser menos estável. Você deve apenas usá-lo em modo de desenvolvimento.

O servidor de desenvolvimento escutará no endereço de IP `127.0.0.1` por padrão, este é o IP que sua máquina usa para se comunicar com ela mesma (`localhost`).
