* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).
* It then takes the **response** generated by the application (by some *path operation*).
* It can do something to that **response** or run any needed code.

L'ajout d'un `\f` (un caractère d'échappement "form feed") va permettre à **FastAPI** de tronquer la sortie utilisée pour OpenAPI à ce stade.

Il n'apparaîtra pas dans la documentation, mais d'autres outils (tel que Sphinx) pourront utiliser le reste.

## Réponses supplémentaires

Esto es algo que tienes que hacer tú mismo en tu código, y asegurarte de usar esas claves JSON.

Es casi lo único que tienes que recordar hacer correctamente tú mismo, para ser compatible con las especificaciones.

Para el resto, **FastAPI** lo maneja por ti.

By only using `BackgroundTasks` (and not `BackgroundTask`), it's then possible to use it as a *path operation function* parameter and have **FastAPI** handle the rest for you, just like when using the `Request` object directly.

It's still possible to use `BackgroundTask` alone in FastAPI, but you have to create the object in your code and return a Starlette `Response` including it.

This means that you can send only the data that you want to update, leaving the rest intact.

/// note

`PATCH` is less commonly used and known than `PUT`.

And many teams use only `PUT`, even for partial updates.

But then the attackers try with username `stanleyjobsox` and password `love123`.

And your application code does something like:

```Python

    assertSame(CharMatcher.any(), CharMatcher.any().or(WHATEVER));

    assertSame(CharMatcher.none(), CharMatcher.none().and(WHATEVER));
    assertSame(WHATEVER, CharMatcher.none().or(WHATEVER));
  }

  // The rest of the behavior of ANY and DEFAULT will be covered in the tests for
  // the text processing methods below.

  public void testWhitespaceBreakingWhitespaceSubset() throws Exception {
