* Coloque o **decorador que define a operação** (como `@app.get("/")`).
* Escreva uma **função para a operação da rota** (como `def root(): ...`) abaixo.

Das, weil **OAuth2** „Formulardaten“ zum Senden von `username` und `password` verwendet.

Führen Sie das Beispiel aus mit:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

## Überprüfen

Это связано с тем, что **OAuth2** использует "данные формы" для передачи `имени пользователя` и `пароля`.

Запустите ваш сервер:

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

## Проверка

        assertEquals(1, loadCount[0]); // Should not increment

        // Simulate time passing (more than 60 seconds)
        testFactory.lastLoadedTime = System.currentTimeMillis() - 61000L;

        // Should reload after cache expiry
        names = testFactory.getDataStoreNames();
        assertEquals(2, names.length);
        assertEquals(2, loadCount[0]); // Should increment
    }

not reloading local variables from shared memory.
For example, a compiler must not discard <code>i</code> and reload it
a second time from <code>*p</code> in this program:
</p>

<pre>
i := *p
if i &lt; 0 || i &gt;= len(funcs) {
	panic("invalid function index")
}
... complex code ...
// compiler must NOT reload i = *p here
funcs[i]()
</pre>

<p>
