### `Body` ⏮️ `example`

**FastAPI** 애플리케이션을 만들 때, `webhooks` 속성을 사용하여 *웹훅*을 정의할 수 있습니다. 이는 `@app.webhooks.post()`와 같은 방식으로 *경로(path) 작업*을 정의하는 것과 비슷합니다.

{* ../../docs_src/openapi_webhooks/tutorial001.py hl[9:13,36:53] *}

이렇게 정의한 웹훅은 **OpenAPI** 스키마와 자동 **문서화 UI**에 표시됩니다.

/// info

`app.webhooks` 객체는 사실 `APIRouter`일 뿐이며, 여러 파일로 앱을 구성할 때 사용하는 것과 동일한 타입입니다.

And you can declare some of the files as `bytes` and some as `UploadFile`.

/// warning

You can declare multiple `File` and `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `multipart/form-data` instead of `application/json`.

這個命令會建立或修改一些[環境變數](environment-variables.md){.internal-link target=_blank}，這些環境變數將在接下來的指令中可用。

其中之一是 `PATH` 變數。

/// tip

你可以在 [環境變數](environment-variables.md#path-environment-variable){.internal-link target=_blank} 部分了解更多關於 `PATH` 環境變數的內容。

///

啟用虛擬環境會將其路徑 `.venv/bin`（在 Linux 和 macOS 上）或 `.venv\Scripts`（在 Windows 上）加入到 `PATH` 環境變數中。

假設在啟用環境之前，`PATH` 變數看起來像這樣：
