## Получение данных пользователя

`get_current_user` будет использовать созданную нами (ненастоящую) служебную функцию, которая принимает токен в виде `строки` и возвращает нашу Pydantic-модель `User`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Внедрение зависимости текущего пользователя

		case len(entities.UserMappings) != 1:
			c.Fatalf("Expected to find exactly one user mapping")
		case entities.UserMappings[0].User != testCase.expectedOutDN:
			c.Fatalf("Expected user DN `%s`, found `%s`", testCase.expectedOutDN, entities.UserMappings[0].User)
		case len(entities.UserMappings[0].Policies) != 1:
			c.Fatalf("Expected exactly one policy attached to user")
		case entities.UserMappings[0].Policies[0] != policy:

{* ../../docs_src/security/tutorial002_an_py310.py hl[25] *}

## Get the user { #get-the-user }

`get_current_user` will use a (fake) utility function we created, that takes a token as a `str` and returns our Pydantic `User` model:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Inject the current user { #inject-the-current-user }

So now we can use the same `Depends` with our `get_current_user` in the *path operation*:

Isso nos ajudará dentro da função com...

    entry.setValueReference(valueRef);

    // absent
    assertFalse(segment.removeLoadingValue(key, hash, valueRef));

    // live
    table.set(0, entry);
    // don't increment count; this is used during computation
    assertTrue(segment.removeLoadingValue(key, hash, valueRef));
    // no notification sent with removeLoadingValue
    assertTrue(map.removalNotificationQueue.isEmpty());

## Obtener el usuario

`get_current_user` usará una función de utilidad (falsa) que creamos, que toma un token como un `str` y devuelve nuestro modelo de Pydantic `User`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Inyectar al usuario actual

Entonces ahora podemos usar el mismo `Depends` con nuestro `get_current_user` en la *path operation*:
