Verás el response JSON como:

```JSON
{"message": "Hello World"}
```

            client.prepareClearScroll().addScrollId(scrollId).execute(ActionListener.wrap(() -> {}));
        }
    }

    @Override
    protected Number doReadNextVal() {
        final String msg = "This table is NOT related to sequence: " + asEsIndexType();
        throw new UnsupportedOperationException(msg);
    }

Sie haben gerade den Haupt-Einsatzort für die Deklaration von Typhinweisen gesehen. Als Funktionsparameter.

Das ist auch meistens, wie sie in **FastAPI** verwendet werden.

### Einfache Typen

Sie können alle Standard-Python-Typen deklarieren, nicht nur `str`.

Zum Beispiel diese:

* `int`
* `float`
* `bool`
* `bytes`

{* ../../docs_src/python_types/tutorial005.py hl[1] *}

	BHI	6(PC)  // BHI 6(PC)    // 0400008a
	BLS	5(PC)  // BLS 5(PC)    // 0300009a
	BGE	4(PC)  // BGE 4(PC)    // 020000aa
	BLT	3(PC)  // BLT 3(PC)    // 010000ba
	BGT	2(PC)  // BGT 2(PC)    // 000000ca
	BLE	1(PC)  // BLE 1(PC)    // ffffffda
	ADD	$0, R0, R0
	B	-1(PC) // JMP -1(PC)   // fdffffea
	B	-2(PC) // JMP -2(PC)   // fcffffea
	B	-3(PC) // JMP -3(PC)   // fbffffea
	B	-4(PC) // JMP -4(PC)   // faffffea

/// tip | Consejo

Nota que incluso aunque estés accediendo en `http://127.0.0.1:8000/app`, muestra el `root_path` de `/api/v1`, tomado de la opción `--root-path`.

Y ahora abre la URL con el puerto para Traefik, incluyendo el prefijo de path: <a href="http://127.0.0.1:9999/api/v1/app" class="external-link" target="_blank">http://127.0.0.1:9999/api/v1/app</a>.
