That tells the browser to show the integrated prompt for a username and password.

Then, when you type that username and password, the browser sends them in the header automatically.

## Simple HTTP Basic Auth { #simple-http-basic-auth }

* Import `HTTPBasic` and `HTTPBasicCredentials`.
* Create a "`security` scheme" using `HTTPBasic`.

Si hubiera tareas en segundo plano (cubiertas en la sección [Tareas en segundo plano](background-tasks.md), lo verás más adelante), se ejecutarán *después* de todo el middleware.

## Crear un middleware { #create-a-middleware }

Para crear un middleware usas el decorador `@app.middleware("http")` encima de una función.

La función middleware recibe:

* La `request`.
* Una función `call_next` que recibirá la `request` como parámetro.

h4. Generation of plugin metadata and packaging

To create the packaging for a plugin a special Maven packaging would be created with an accompanying life-cycle in order to create the plugin metadata required and create an archive of the plugin that can be consumed at runtime.

  @Test
  fun multipartBodyPart() {
    val requestBody: RequestBody = "".toRequestBody(null)
    var part: MultipartBody.Part = MultipartBody.Part.create(null, requestBody)
    part = MultipartBody.Part.create(headersOf(), requestBody)
    part = MultipartBody.Part.create(requestBody)
    part = MultipartBody.Part.createFormData("", "")
    part = MultipartBody.Part.createFormData("", "", requestBody)

**FastAPI** creará el objeto de tipo `BackgroundTasks` por ti y lo pasará como ese parámetro.

## Crear una función de tarea { #create-a-task-function }

Crea una función para que se ejecute como la tarea en segundo plano.

Es solo una función estándar que puede recibir parámetros.

```console
$ pip install sqlmodel

## Crear o App com um Único Modelo { #create-the-app-with-a-single-model }

Vamos criar a primeira versão mais simples do app com um único modelo **SQLModel**.

Depois, vamos melhorá-lo aumentando a segurança e versatilidade com **múltiplos modelos** abaixo. 🤓

### Criar Modelos { #create-models }

Importe o `SQLModel` e crie um modelo de banco de dados:

errors.invalid_query_cannot_process=Impossibile elaborare la query specificata.
errors.crud_invalid_mode = Modalità non valida. (È {1}, non {0})
errors.crud_failed_to_create_instance = Impossibile creare nuovi dati.
errors.crud_failed_to_create_crud_table = Impossibile creare nuovi dati. ({0})
errors.crud_failed_to_update_crud_table=Impossibile aggiornare i dati. ({0})
errors.crud_failed_to_delete_crud_table=Impossibile eliminare i dati. ({0})

	defer cancel()

	// Create project buckets
	buckets := []string{"projecta", "projectb", "projectaorb", "other"}
	for _, bucket := range buckets {
		err := s.client.MakeBucket(ctx, bucket, minio.MakeBucketOptions{})
		if err != nil {
			c.Fatalf("bucket create error: %v", err)
		}
	}

	// Create policies
	for polName, polContent := range policyProjectsMap {

    /**
     * Creates a new class realm with the specified parent and imports.
     *
     * @param baseRealmId The base id to use for the new realm, must not be {@code null}.
     * @param type The type of the class realm, must not be {@code null}.
     * @param parent The parent realm for the new realm, may be {@code null}.
     * @param parentImports The packages/types to import from the parent realm, may be {@code null}.
