You can define this *startup* and *shutdown* logic using the `lifespan` parameter of the `FastAPI` app, and a "context manager" (I'll show you what that is in a second).

Let's start with an example and then see it in detail.

We create an async function `lifespan()` with `yield` like this:

{* ../../docs_src/events/tutorial003_py310.py hl[16,19] *}

///

### Einen Callback-`APIRouter` erstellen { #create-a-callback-apirouter }

Erstellen Sie zunächst einen neuen `APIRouter`, der einen oder mehrere Callbacks enthält.

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### Die Callback-*Pfadoperation* erstellen { #create-the-callback-path-operation }

/// tip

當你使用 OAuth2 時，`swagger_ui_redirect` 的路徑操作是個輔助端點。

如果你把 API 與 OAuth2 提供者整合，便能完成認證並帶著取得的憑證回到 API 文件，接著以真正的 OAuth2 驗證與之互動。

Swagger UI 會在背後幫你處理，不過它需要這個「redirect」輔助端點。

///

### 建立路徑操作以進行測試 { #create-a-path-operation-to-test-it }

現在，為了測試一切是否正常，建立一個路徑操作：

{* ../../docs_src/custom_docs_ui/tutorial001_py310.py hl[36:38] *}

### 測試 { #test-it }

		writeCustomErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrInternalError), err.Error(), r.URL)
		return
	}
	writeSuccessResponseJSON(w, v)
