Framing rules make it impractical to implement http/2 correctly on a single blocking thread. The flow-control features introduce feedback between reads and writes, requiring writes to acknowledge reads and reads to throttle writes.

...no tiene ningún significado especial para **FastAPI**. **FastAPI** no lo usará para la conversión de datos, validación, etc. (ya que está usando `Depends(CommonQueryParams)` para eso).

De hecho, podrías escribir simplemente:

//// tab | Python 3.8+

```Python
commons: Annotated[Any, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.8+ sin `Annotated`

/// tip | Consejo

Así que importas `Query`, que es una función. Y cuando la llamas, retorna una instance de una clase también llamada `Query`.

Estas funciones están allí (en lugar de usar simplemente las clases directamente) para que tu editor no marque errores sobre sus tipos.

De esa forma puedes usar tu editor y herramientas de programación normales sin tener que agregar configuraciones personalizadas para omitir esos errores.

You will get an "Inactive user" error, like:

```JSON
{
  "detail": "Inactive user"
}
```

## Recap { #recap }

You now have the tools to implement a complete security system based on `username` and `password` for your API.

Using these tools, you can make the security system compatible with any database and with any user or data model.

   * Schedules [task] for execution in [delayNanos]. A task may only have one future execution
   * scheduled. If the task is already in the queue, the earliest execution time is used.
   *
   * The target execution time is implemented on a best-effort basis. If another task in this queue
   * is running when that time is reached, that task is allowed to complete before this task is
   * started. Similarly the task will be delayed if the host lacks compute resources.

 * This class manages the rules defined in a robots.txt file, including user agent directives,
 * allowed/disallowed paths, crawl delays, and sitemap URLs.
 *
 * <p>The robots.txt protocol is implemented according to the standard specification,
 * supporting pattern matching for user agents, path-based access control, and crawl delay settings.</p>

            immutableCell("two", "dos", 4));

  // This function specifically returns a BiPredicate, because Guava7’s Equivalence class does not
  // actually implement BiPredicate, and CollectorTests expects a BiPredicate.
  static <C, E extends @Nullable Object, R extends Iterable<E>>
      BiPredicate<C, C> pairwiseOnResultOf(Function<C, R> arg) {

Luego simplemente haces lo mismo en tus pruebas.

Por ejemplo:

* Para pasar un parámetro de *path* o *query*, añádelo a la URL misma.
* Para pasar un cuerpo JSON, pasa un objeto de Python (por ejemplo, un `dict`) al parámetro `json`.
