Ancak FastAPI, [`dataclasses`](https://docs.python.org/3/library/dataclasses.html) kullanmayı da aynı şekilde destekler:

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

Bu destek hâlâ **Pydantic** sayesinde vardır; çünkü Pydantic, [`dataclasses` için dahili destek](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel) sunar.

## Code Examples

[Using minio-go library](https://github.com/minio/minio/blob/master/docs/extensions/s3zip/examples/minio-go/main.go)
[Using AWS JS SDK v2](https://github.com/minio/minio/blob/master/docs/extensions/s3zip/examples/aws-js/main.js)
[Using boto3](https://github.com/minio/minio/blob/master/docs/extensions/s3zip/examples/boto3/main.py)

## Requirements and limits

# Deployment { #deployment }

Deploying a **FastAPI** application is relatively easy.

## What Does Deployment Mean { #what-does-deployment-mean }

To **deploy** an application means to perform the necessary steps to make it **available to the users**.

가이드를 따라 하고 서비스를 사용해보기 위해 이들도 고려해볼 수 있습니다:

* [Render](https://docs.render.com/deploy-fastapi?utm_source=deploydoc&utm_medium=referral&utm_campaign=fastapi)

# Swagger-Oberfläche konfigurieren { #configure-swagger-ui }

Sie können einige zusätzliche [Parameter der Swagger-Oberfläche](https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration/) konfigurieren.

Um diese zu konfigurieren, übergeben Sie das Argument `swagger_ui_parameters` beim Erstellen des `FastAPI()`-App-Objekts oder an die Funktion `get_swagger_ui_html()`.

**FastAPI** **извлечёт** данные для **каждого поля** из **cookies**, полученных в запросе, и выдаст вам объявленную Pydantic-модель.

## Проверка сгенерированной документации { #check-the-docs }

Вы можете посмотреть объявленные cookies в графическом интерфейсе Документации по пути `/docs`:

# CORS (Cross-Origin Resource Sharing) { #cors-cross-origin-resource-sharing }

[CORS veya "Cross-Origin Resource Sharing"](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS), tarayıcıda çalışan bir frontend’in JavaScript kodunun bir backend ile iletişim kurduğu ve backend’in frontend’den farklı bir "origin"de olduğu durumları ifade eder.

## Origin { #origin }

### 檢查文件 UI { #check-the-docs-ui }

接下來是有趣的部分。✨

「正式」的存取方式應該是透過我們定義了路徑前綴的代理。因此，如我們預期，如果你直接透過 Uvicorn 供應的文件 UI、而 URL 中沒有該路徑前綴，那它不會運作，因為它預期要透過代理來存取。

你可以在 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs) 檢查：

但如果我們改用「正式」的 URL，也就是使用埠號 `9999` 的代理、並在 `/api/v1/docs`，它就能正確運作了！🎉
