Pour ceux qui se demandent, "AlexNet", "ResNet", et "LeNet" sont juste des noms de <abbr title="Techniquement, des architectures de modèles">modèles</abbr> de Machine Learning.

For example, you can create a subclass of `HTTPBearer` that returns a `403 Forbidden` error instead of the default `401 Unauthorized` error:

{* ../../docs_src/authentication_error_status_code/tutorial001_an_py39.py hl[9:13] *}

/// tip

Notice that the function returns the exception instance, it doesn't raise it. The raising is done in the rest of the internal code.

Por exemplo, você pode criar uma subclasse de `HTTPBearer` que retorne um erro `403 Forbidden` em vez do erro padrão `401 Unauthorized`:

{* ../../docs_src/authentication_error_status_code/tutorial001_an_py39.py hl[9:13] *}

/// tip | Dica

Perceba que a função retorna a instância da exceção, ela não a lança. O lançamento é feito no restante do código interno.

{* ../../docs_src/authentication_error_status_code/tutorial001_an_py39.py hl[9:13] *}

/// tip | Tipp

Beachten Sie, dass die Funktion die Exception-Instanz zurückgibt; sie wirft sie nicht. Das Werfen erfolgt im restlichen internen Code.

**SQLModel**은 <a href="https://www.sqlalchemy.org/" class="external-link" target="_blank">SQLAlchemy</a>와 Pydantic을 기반으로 구축되었습니다.SQLModel은 **SQL 데이터베이스**를 사용하는 FastAPI 애플리케이션에 완벽히 어울리도록 **FastAPI**의 제작자가 설계한 도구입니다.

/// tip | 팁

다른 SQL 또는 NoSQL 데이터베이스 라이브러리를 사용할 수도 있습니다 (일부는 <abbr title="객체 관계 매퍼(Object Relational Mapper), SQL 테이블을 나타내는 클래스를 제공하고 테이블의 행을 인스턴스로 표현하는 라이브러리를 지칭하는 용어">"ORM"</abbr>이라고도 불립니다), FastAPI는 특정 라이브러리의 사용을 강요하지 않습니다. 😎

    @Test
    public void test_chainWithCustomNormalizer() throws Exception {
        NormalizerChain chain = new NormalizerChain();
        chain.add((text, field, langs) -> text.trim());
        chain.add((text, field, langs) -> text.toLowerCase());
        chain.add((text, field, langs) -> text.replace(" ", "_"));

        String result = chain.normalize("  TEST CASE  ", "field");

Then create class attributes with fixed values, which will be the available valid values:

{* ../../docs_src/path_params/tutorial005_py39.py hl[1,6:9] *}

/// tip

If you are wondering, "AlexNet", "ResNet", and "LeNet" are just names of Machine Learning <abbr title="Technically, Deep Learning model architectures">models</abbr>.

///

Luego crea atributos de clase con valores fijos, que serán los valores válidos disponibles:

{* ../../docs_src/path_params/tutorial005_py39.py hl[1,6:9] *}

/// tip | Consejo

Si te estás preguntando, "AlexNet", "ResNet" y "LeNet" son solo nombres de <abbr title="Técnicamente, arquitecturas de modelos de Deep Learning">modelos</abbr> de Machine Learning.

///

Там вы можете задать:

* "Item ID", используемый в пути.
* "Token", используемый как query-параметр.

/// tip | Подсказка

Обратите внимание, что query-параметр `token` будет обработан в зависимости.
