### 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 }

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_py39.py hl[16,19] *}

	if err != nil {
		writeCustomErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrInternalError), err.Error(), r.URL)
		return
	}
	writeSuccessResponseJSON(w, v)
}

// KMSCreateKeyHandler - POST /minio/kms/v1/key/create?key-id=<master-key-id>
func (a kmsAPIHandlers) KMSCreateKeyHandler(w http.ResponseWriter, r *http.Request) {
	// If env variable MINIO_KMS_SECRET_KEY is populated, prevent creation of new keys

 * attributes for business methods.
 * <p>
 * For example:
 *
 * <pre>
 * &#064;Secured({ &quot;ROLE_USER&quot; })
 * public void create(Contact contact);
 *
 * &#064;Secured({ &quot;ROLE_USER&quot;, &quot;ROLE_ADMIN&quot; })
 * public void update(Contact contact);
 *
 * &#064;Secured({ &quot;ROLE_ADMIN&quot; })
 * public void delete(Contact contact);
