## Usa el objeto `Request` directamente

Imaginemos que quieres obtener la dirección IP/host del cliente dentro de tu *path operation function*.

Para eso necesitas acceder al request directamente.

{* ../../docs_src/using_request_directly/tutorial001.py hl[1,7:8] *}

Al declarar un parámetro de *path operation function* con el tipo siendo `Request`, **FastAPI** sabrá pasar el `Request` en ese parámetro.

                    HtmlNext htmlNext = (HtmlNext) field.get(null);
                    String path = htmlNext.getRoutingPath();
                    assertFalse("Duplicate path found: " + path + " in field " + field.getName(), paths.contains(path));
                    paths.add(path);
                }
            }
        }
        assertTrue("Should have unique paths", paths.size() > 0);
    }

Eso es todo.

**2 líneas**.

Y tiene la misma forma y estructura que todas tus *path operation functions*.

Puedes pensar en ella como una *path operation function* sin el "decorador" (sin el `@app.get("/some-path")`).

Y puede devolver lo que quieras.
