Here we declare the setting `openapi_url` with the same default of `"/openapi.json"`.

And then we use it when creating the `FastAPI` app.

Then you could disable OpenAPI (including the UI docs) by setting the environment variable `OPENAPI_URL` to the empty string, like:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

{* ../../docs_src/request_form_models/tutorial001_an_py39.py hl[9:11,15] *}

**FastAPI**는 요청에서 받은 **폼 데이터**에서 **각 필드**에 대한 데이터를 **추출**하고 정의한 Pydantic 모델을 줍니다.

## 문서 확인하기

문서 UI `/docs`에서 확인할 수 있습니다:

<div class="screenshot">
<img src="/img/tutorial/request-form-models/image01.png">
</div>

## 추가 폼 필드 금지하기

{* ../../docs_src/query_param_models/tutorial001_an_py310.py hl[9:13,17] *}

**FastAPI** 將會從請求的**查詢參數**中**提取**出**每個欄位**的資料，並將其提供給你定義的 Pydantic 模型。

## 查看文件

你可以在 `/docs` 頁面的 UI 中查看查詢參數：

<div class="screenshot">
<img src="/img/tutorial/query-param-models/image01.png">
</div>

## 禁止額外的查詢參數

在一些特殊的使用場景中（可能不是很常見），你可能希望**限制**你要收到的查詢參數。

### 문서 자동화

대화형 API 문서와 웹 탐색 유저 인터페이스를 제공합니다. 프레임워크가 OpenAPI를 기반으로 하기에, 2가지 옵션이 기본적으로 들어간 여러 옵션이 존재합니다.

* 대화형 탐색 <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank"><strong>Swagger UI</strong></a>를 이용해, 브라우저에서 바로 여러분의 API를 호출하거나 테스트할 수 있습니다.

![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-03-swagger-02.png)

The authentication flow is similar to that of OpenID, however the token is "opaque" to MinIO - it is simply sent to the plugin for verification. CAVEAT: There is no console UI integration for this method of authentication and it is intended primarily for machine authentication.

That way, the sub-application will know to use that path prefix for the docs UI.

And the sub-application could also have its own mounted sub-applications and everything would work correctly, because FastAPI handles all these `root_path`s automatically.

Also, before that, in previous versions, the `request` object was passed as part of the key-value pairs in the context for Jinja2.

///

/// tip

By declaring `response_class=HTMLResponse` the docs UI will be able to know that the response will be HTML.

///

/// note | Technical Details

You could also use `from starlette.templating import Jinja2Templates`.

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Gehen Sie dann zur `/docs`-UI, Sie werden sehen, dass **FastAPI** diese **Modelle** verwendet, um die API zu **dokumentieren**, und es wird sie auch verwenden, um die Daten zu **serialisieren** und zu **validieren**.

<div class="screenshot">

				ReplicationValidityCheck: true, // set this to validate the replication config
			},
		}
		obj := path.Join(minioReservedBucket, globalLocalNodeNameHex, "deleteme")
		ui, err := c.PutObject(ctx, clnt.Bucket, obj, reader, int64(len(buf)), "", "", putOpts)
		if err != nil && !isReplicationPermissionCheck(ErrorRespToObjectError(err, bucket, obj)) {

{* ../../docs_src/openapi_webhooks/tutorial001_py39.py hl[9:13,36:53] *}

The webhooks that you define will end up in the **OpenAPI** schema and the automatic **docs UI**.

/// info

The `app.webhooks` object is actually just an `APIRouter`, the same type you would use when structuring your app with multiple files.
