### Crear un `APIRouter` de callback

Primero crea un nuevo `APIRouter` que contendrá uno o más callbacks.

{* ../../docs_src/openapi_callbacks/tutorial001.py hl[3,25] *}

### Crear la *path operation* del callback

Para crear la *path operation* del callback utiliza el mismo `APIRouter` que creaste anteriormente.

Debería verse como una *path operation* normal de FastAPI:

            return result;
        } catch (Exception e) {
            log.warn("Failed to create fresh context, using singleton", e);
            try {
                // Fallback to singleton with fresh auth
                NtlmPasswordAuthentication auth =
                        new NtlmPasswordAuthentication(SingletonContext.getInstance(), WORKGROUP, USERNAME, PASSWORD);

	createCallback.Clauses = config.CreateClauses

	queryCallback := db.Callback().Query()
	queryCallback.Register("gorm:query", Query)
	queryCallback.Register("gorm:preload", Preload)
	queryCallback.Register("gorm:after_query", AfterQuery)
	queryCallback.Clauses = config.QueryClauses

	deleteCallback := db.Callback().Delete()
	deleteCallback.Match(enableTransaction).Register("gorm:begin_transaction", BeginTransaction)

        IndexUpdateCallback callback1 = createMockCallback(10, 500);
        IndexUpdateCallback callback2 = createMockCallback(20, 1000);

        assertEquals(10L, callback1.getDocumentSize());
        assertEquals(500L, callback1.getExecuteTime());

        assertEquals(20L, callback2.getDocumentSize());
        assertEquals(1000L, callback2.getExecuteTime());

        // Test store operations
        DataStoreParams params = new DataStoreParams();

### Einen Callback-`APIRouter` erstellen

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

{* ../../docs_src/openapi_callbacks/tutorial001.py hl[3,25] *}

### Die Callback-*Pfadoperation* erstellen

Um die Callback-*Pfadoperation* zu erstellen, verwenden Sie denselben `APIRouter`, den Sie oben erstellt haben.

///

### Create a callback `APIRouter` { #create-a-callback-apirouter }

First create a new `APIRouter` that will contain one or more callbacks.

{* ../../docs_src/openapi_callbacks/tutorial001.py hl[3,25] *}

### Create the callback *path operation* { #create-the-callback-path-operation }

To create the callback *path operation* use the same `APIRouter` you created above.

  }

  private static String scopeWithDelimiter(Inet6Address ip) {
    // getHostAddress on android sometimes maps the scope ID to an invalid interface name; if the
    // mapped interface isn't present, fallback to use the scope ID (which has no validation against
    // present interfaces)
    NetworkInterface scopedInterface = ip.getScopedInterface();
    if (scopedInterface != null) {
      return "%" + scopedInterface.getName();

///

### Criar um `APIRouter` para o callback

Primeiramente crie um novo `APIRouter` que conterá um ou mais callbacks.

{* ../../docs_src/openapi_callbacks/tutorial001.py hl[3,25] *}

### Crie a *operação de rota* do callback

Para criar a *operação de rota* do callback, use o mesmo `APIRouter` que você criou acima.

Ele deve parecer exatamente como uma *operação de rota* normal do FastAPI:

    server.protocolNegotiationEnabled = true
    server.protocols = client.protocols
  }

  /**
   * Used during tests that involve TLS connection fallback attempts. OkHttp includes the
   * TLS_FALLBACK_SCSV cipher on fallback connections. See [FallbackTestClientSocketFactory]
   * for details.
   */

    e: IOException,
  )

  /**
   * Called when the HTTP response was successfully returned by the remote server. The callback may
   * proceed to read the response body with [Response.body]. The response is still live until its
   * response body is [closed][ResponseBody]. The recipient of the callback may consume the response
   * body on another thread.
   *
