Like `/users/me`, let's say that it's to get data about the current user.

And then you can also have a path `/users/{user_id}` to get data about a specific user by some user ID.

Because *path operations* are evaluated in order, you need to make sure that the path for `/users/me` is declared before the one for `/users/{user_id}`:

{* ../../docs_src/path_params/tutorial003.py hl[6,11] *}

El beneficio de lanzar una excepción en lugar de `return`ar un valor será más evidente en la sección sobre Dependencias y Seguridad.

En este ejemplo, cuando el cliente solicita un ítem por un ID que no existe, lanza una excepción con un código de estado de `404`:

{* ../../docs_src/handling_errors/tutorial001.py hl[11] *}

### El response resultante

Como `/users/me`, imaginemos que es para obtener datos sobre el usuario actual.

Y luego también puedes tener un path `/users/{user_id}` para obtener datos sobre un usuario específico por algún ID de usuario.

Debido a que las *path operations* se evalúan en orden, necesitas asegurarte de que el path para `/users/me` se declara antes que el de `/users/{user_id}`:

{* ../../docs_src/path_params/tutorial003.py hl[6,11] *}

    * Wenn Sie Uvicorn direkt ausführen würden, würden Sie anstelle von `--bind 0.0.0.0:80` (die Gunicorn-Option) stattdessen `--host 0.0.0.0` und `--port 80` verwenden.

In der Ausgabe können Sie sehen, dass die **PID** (Prozess-ID) jedes Prozesses angezeigt wird (es ist nur eine Zahl).

Sie können sehen, dass:

* Der Gunicorn **Prozessmanager** beginnt, mit der PID `19499` (in Ihrem Fall ist es eine andere Nummer).

    /**

    /**

    @Nonnull
    default String getId() {
        return getModel().getId();
    }

    /**

O benefício de lançar uma exceção em vez de retornar um valor ficará mais evidente na seção sobre Dependências e Segurança.

Neste exemplo, quando o cliente pede, na requisição, por um item cujo ID não existe, a exceção com o status code `404` é lançada:

{* ../../docs_src/handling_errors/tutorial001.py hl[11] *}

        int referent1 = Encdec.dec_uint32le(buffer, 0);
        assertTrue(referent1 > 0); // Should be a positive referent ID

        ndrBuffer.reset();
        ndrBuffer.enc_ndr_referent(obj1, 2); // Same object, should get same referent
        assertEquals(4, ndrBuffer.getIndex());

The benefit of raising an exception over returning a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:

{* ../../docs_src/handling_errors/tutorial001.py hl[11] *}
