Crea una variable `ALGORITHM` con el algoritmo usado para firmar el token JWT y configúralo a `"HS256"`.

Crea una variable para la expiración del token.

Define un Modelo de Pydantic que se usará en el endpoint de token para el response.

Crea una función de utilidad para generar un nuevo token de acceso.

## Create a TypeScript SDK { #create-a-typescript-sdk }

Let's start with a simple FastAPI application:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Notice that the *path operations* define the models they use for request payload and response payload, using the models `Item` and `ResponseMessage`.

### API Docs { #api-docs }

Aber der Facebook Login unterstützt OpenID Connect nicht. Es hat seine eigene Variante von OAuth2.

### OpenID (nicht „OpenID Connect“)

Es gab auch eine „OpenID“-Spezifikation. Sie versuchte das Gleiche zu lösen wie **OpenID Connect**, basierte aber nicht auf OAuth2.

Es handelte sich also um ein komplett zusätzliches System.

import jakarta.annotation.Resource;

/**
 * API action for admin file authentication management.
 * Provides RESTful API endpoints for managing file authentication settings in the Fess search engine.
 * File authentication settings define access credentials and permissions for file-based crawling.
 *
 */
public class ApiAdminFileauthAction extends FessApiAdminAction {

    private static final Logger logger = LogManager.getLogger(ApiAdminFileauthAction.class);

        assertEquals(name, parsed.toString(), "toString should return the name");
        assertEquals(testOid().hashCode(), parsed.hashCode(), "hashCode should derive from OID");
    }

    @Test
    @DisplayName("Parses empty name length (NAME_LEN=0) as empty string")
    void parseEmptyName() {
        // Arrange
        String name = "";

Following are advantages for using temporary credentials:

- Eliminates the need to embed long-term credentials with an application.
- Eliminates the need to provide access to buckets and objects without having to define static credentials.
- Temporary credentials have a limited lifetime, there is no need to rotate them or explicitly revoke them. Expired temporary credentials cannot be reused.

## Adicionando expressões regulares

Você pode definir uma <abbr title="Uma expressão regular, regex ou regexp é uma sequência de caracteres que define um parâmetro de busca para textos.">expressão regular</abbr> que combine com um padrão esperado pelo parâmetro:

{* ../../docs_src/query_params_str_validations/tutorial004.py hl[11] *}

Das `Union` in `Union[str, None]` wird von FastAPI nicht verwendet, aber es erlaubt Ihrem Editor, Sie besser zu unterstützen und Fehler zu erkennen.
