## Benefits { #benefits }

When using the automatically generated clients, you would get **autocompletion** for:

* Methods.
* Request payloads in the body, query parameters, etc.
* Response payloads.

You would also have **inline errors** for everything.

      required: true

  - type: textarea
    id: osVersion
    attributes:
      label: OS version
      value: |
        <details>

        ```console
        # On Linux:
        $ cat /etc/os-release
        # paste output here
        $ uname -a
        # paste output here

        # On Windows:
        C:\> wmic os get Caption, Version, BuildNumber, OSArchitecture
        # paste output here

Los contenedores de Linux se ejecutan utilizando el mismo núcleo de Linux del host (máquina, máquina virtual, servidor en la nube, etc.). Esto significa que son muy ligeros (en comparación con las máquinas virtuales completas que emulan un sistema operativo completo).

    /**
     * Gets the remote host name for this tree connection
     * @return the remote host name
     */
    String getRemoteHostName();

    /**
     * Gets the tree type (share type such as disk, printer, pipe, etc.)
     * @return the tree type
     */
    int getTreeType();

/// warning

When you return a `Response` directly, like in the example above, it will be returned directly.

It won't be serialized with a model, etc.

Make sure it has the data you want it to have, and that the values are valid JSON (if you are using `JSONResponse`).

public class CreateForm {

    /**
     * Creates a new CreateForm instance.
     */
    public CreateForm() {
        // Default constructor
    }

    /** CRUD operation mode (CREATE, EDIT, etc.) */
    @ValidateTypeFailure
    public Integer crudMode;

    /** URL expression pattern to match documents for boosting */
    @Required
    @Size(max = 10000)
    public String urlExpr;

public class CreateForm {

    /**
     * Creates a new CreateForm instance.
     */
    public CreateForm() {
    }

    /**
     * The CRUD operation mode (create, update, etc.).
     */
    @ValidateTypeFailure
    public Integer crudMode;

    /**
     * The search term for which related content is shown.
     */
    @Required
    @Size(max = 10000)
    public String term;

But that will only allow certain types of communication, excluding everything that involves credentials: Cookies, Authorization headers like those used with Bearer Tokens, etc.

So, for everything to work correctly, it's better to specify explicitly the allowed origins.

## Use `CORSMiddleware` { #use-corsmiddleware }

Isso é diferente de usar um `APIRouter`, pois um aplicativo montado é completamente independente. A OpenAPI e a documentação do seu aplicativo principal não incluirão nada do aplicativo montado, etc.

Você pode ler mais sobre isso no **Guia Avançado do Usuário**.

## Detalhes

    * <a href="https://fastapi.tiangolo.com/features/" class="external-link" target="_blank">**Et bien d'autres fonctionnalités**</a> comme la validation automatique, la sérialisation, l'authentification avec OAuth2 JWT tokens, etc.
* Hashage de **mots de passe sécurisé** par défaut.
* Authentification par **jetons JWT**.
* Modèles **SQLAlchemy** (indépendants des extensions Flask, afin qu'ils puissent être utilisés directement avec des *workers* Celery).
