Você pode definir manipuladores de eventos (funções) que precisam ser executados antes de a aplicação iniciar ou quando a aplicação estiver encerrando.

Essas funções podem ser declaradas com `async def` ou `def` normal.

### Evento `startup` { #startup-event }

Para adicionar uma função que deve rodar antes de a aplicação iniciar, declare-a com o evento `"startup"`:

{* ../../docs_src/events/tutorial001_py310.py hl[8] *}

// Tests extracting bucket and objectname from various types of paths.
func TestPath2BucketObjectName(t *testing.T) {
	testCases := []struct {
		path           string
		bucket, object string
	}{
		// Test case 1 normal case.
		{
			path:   "/bucket/object",
			bucket: "bucket",
			object: "object",
		},
		// Test case 2 where url only has separator.
		{
			path:   SlashSeparator,
			bucket: "",
			object: "",

import org.junit.jupiter.api.Test;

public class ResultOffsetExceededExceptionTest extends UnitFessTestCase {

    @Test
    public void test_constructor_withMessage() {
        // Test with normal message
        String message = "Offset exceeded the limit";
        ResultOffsetExceededException exception = new ResultOffsetExceededException(message);

        assertEquals(message, exception.getMessage());

## FastAPI'yi Kurun { #install-fastapi }

İlk adım FastAPI'yi kurmaktır.

Bir [sanal ortam](../virtual-environments.md) oluşturduğunuzdan emin olun, etkinleştirin ve ardından **FastAPI'yi kurun**:

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

                .withParameter("and-another-thing", "")
                .withParameter("normal-thing", "foo")
                .toString())
        .isEqualTo(
            "text/plain; something=\"cr@zy\"; something-else=\"crazy with spaces\";"
                + " and-another-thing=\"\"; normal-thing=foo");
  }

    static {
        // Initialize long key with predictable data
        Arrays.fill(LONG_TEST_KEY, (byte) 0xAB);
    }

    @Test
    void testConstructorWithNormalKey() {
        // Test constructor with a normal length key
        HMACT64 hmac = new HMACT64(TEST_KEY);
        assertNotNull(hmac);
    }

    @Test
    void testConstructorWithLongKey() {
        // Test constructor with a key longer than BLOCK_LENGTH (64 bytes)

 * {@code com.google.common.util.concurrent}) in degenerate class loaders which make certain
 * platform classes unavailable. Then we construct a test suite so we can run the normal
 * AbstractFutureTest test methods in these degenerate classloaders.

Mas, em muitos casos, ler um arquivo ou um objeto semelhante a arquivo bloquearia.

Para evitar bloquear o loop de eventos, você pode simplesmente declarar a função de operação de rota com `def` normal em vez de `async def`. Assim, o FastAPI a executará em um worker de threadpool, evitando bloquear o loop principal.

### Target language

Translate to German (Deutsch).

Language code: de.

### Grammar to use when talking to the reader

Use the formal grammar (use `Sie` instead of `Du`).

### Quotes

1) Convert neutral double quotes (`"`) to German double typographic quotes (`„` and `“`). Convert neutral single quotes (`'`) to German single typographic quotes (`‚` and `‘`).

Vous pouvez définir des gestionnaires d'événements (fonctions) qui doivent être exécutés avant le démarrage de l'application, ou lorsque l'application s'arrête.

Ces fonctions peuvent être déclarées avec `async def` ou un `def` normal.

### Événement `startup` { #startup-event }

Pour ajouter une fonction qui doit être exécutée avant le démarrage de l'application, déclarez-la avec l'événement « startup » :
