<h3 id="symbols">Symbols</h3>

<p>
Some symbols, such as <code>R1</code> or <code>LR</code>,
are predefined and refer to registers.
The exact set depends on the architecture.
</p>

<p>
There are four predeclared symbols that refer to pseudo-registers.
These are not real registers, but rather virtual registers maintained by
the toolchain, such as a frame pointer.

Şimdi bunu yönetmek için **FastAPI**’nin sağladığı araçları kullanalım.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Önce `OAuth2PasswordRequestForm`’u import edin ve `/token` için *path operation* içinde `Depends` ile dependency olarak kullanın:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm`, şu alanları içeren bir form body tanımlayan bir class dependency’sidir:

* `username`.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Сначала импортируйте `OAuth2PasswordRequestForm` и затем используйте её как зависимость с `Depends` в операции пути для `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` — это зависимость-класс, которая объявляет тело формы со следующими полями:

* `username`.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Importieren Sie zunächst `OAuth2PasswordRequestForm` und verwenden Sie es als Abhängigkeit mit `Depends` in der *Pfadoperation* für `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` ist eine Klassenabhängigkeit, die einen Formularbody deklariert mit:

* Dem `username`.

Ahora vamos a usar las utilidades proporcionadas por **FastAPI** para manejar esto.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Primero, importa `OAuth2PasswordRequestForm`, y úsalo como una dependencia con `Depends` en la *path operation* para `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` es una dependencia de clase que declara un body de formulario con:

* El `username`.

    cache.refresh(2);
    checkLoggedCause(e);

    assertThat(cache.getUnchecked(2)).isEqualTo("2");
    assertThat(removalListener.getCount()).isEqualTo(0);
  }


  @AndroidIncompatible // Depends on GC behavior
  public void testReloadAfterValueReclamation() throws InterruptedException, ExecutionException {
    CountingLoader countingLoader = new CountingLoader();
    LoadingCache<Object, Object> cache =

	void
	_cgo_gcc_Cfunc_sin(void *v)
	{
		struct {
			double p0;
			double r;
		} __attribute__((__packed__)) *a = v;
		a->r = sin(a->p0);
	}

What happens at link time depends on whether the final binary is linked
using the internal or external mode. If other packages are compiled in
"external only" mode, then the final link will be an external one.
Otherwise the link will be an internal one.

// TF_SessionRun will no longer extend the session on every call.
//
// We expose this here to allow fine-grained synchronization in multi-threaded
// workloads, which is required since the Python implementation depends on the
// above mutation methods. This allows us to prevent modifications to nodes in
// the graph after the session has been made aware of them.
TF_CAPI_EXPORT extern void TF_ExtendSession(TF_Session* session,

Utilisons maintenant les utilités fournies par **FastAPI** pour gérer cela.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Tout d'abord, importez `OAuth2PasswordRequestForm`, et utilisez-la en tant que dépendance avec `Depends` dans le chemin d'accès pour `/token` :

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` est une dépendance de classe qui déclare un corps de formulaire avec :

* Le `username`.

Agora vamos usar os utilitários fornecidos pelo **FastAPI** para lidar com isso.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Primeiro, importe `OAuth2PasswordRequestForm` e use-o como uma dependência com `Depends` na *operação de rota* para `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` é uma dependência de classe que declara um corpo de formulário com:

* O `username`.
