Vous pouvez aussi combiner `dataclasses` avec d'autres annotations de type pour créer des structures de données imbriquées.

Dans certains cas, vous devrez peut‑être encore utiliser la version `dataclasses` de Pydantic. Par exemple, si vous rencontrez des erreurs avec la documentation d'API générée automatiquement.

Dans ce cas, vous pouvez simplement remplacer les `dataclasses` standard par `pydantic.dataclasses`, qui est un remplacement drop‑in :

        .Builder()
        .certificateAuthority(3)
        .commonName("Jurassic Park")
        .organizationalUnit("Gene Research")
        .addSubjectAlternativeName("*.example.com")
        .addSubjectAlternativeName("www.example.org")
        .validityInterval(-1000L, 2000L)
        .serialNumber(17L)
        .build()

    val certificateByteString = certificate.certificate.encoded.toByteString()

```json
{
    "reason": <string>
}
```

The reason message is returned to the client.

## Example Plugin Implementation

        helpUrl = systemHelper.getHelpUrl("https://example.com/{lang}/{version}/test.html");
        assertEquals("https://example.com/98.76/test.html", helpUrl);
    }

    @Test
    public void test_getDefaultHelpLink() {
        String defaultLink = systemHelper.getDefaultHelpLink("https://example.com/{lang}/{version}/test.html");
        assertEquals("https://example.com/98.76/test.html", defaultLink);
    }

    @Test

    public void test_offer_and_drainAll() {
        LogNotificationHelper helper = new LogNotificationHelper();
        helper.offer(new LogNotificationEvent(1000L, "ERROR", "com.example.Foo", "message1", "throwable1"));
        helper.offer(new LogNotificationEvent(2000L, "WARN", "com.example.Bar", "message2", null));

        List<LogNotificationEvent> events = helper.drainAll();
        assertEquals(2, events.size());

 * possible sequences of these operations, up to a given number of steps. So, if the caller
 * specifies to use <i>n</i> steps, a total of <i>3^n</i> tests are actually performed.
 *
 * <p>For instance, if <i>steps</i> is 5, one example sequence that will be tested is:
 *
 * <ol>
 *   <li>remove();
 *   <li>hasNext()
 *   <li>hasNext();
 *   <li>remove();
 *   <li>next();
 * </ol>
 *

     * If the {@linkplain #getBaseVersion() base version} contains a meta-version such as {@code SNAPSHOT},
     * those keywords are replaced by, for example, the actual timestamp.
     *
     * @see ArtifactCoordinates#getVersionConstraint()
     */
    @Nonnull
    Version getVersion();

    /**
     * {@return the version or meta-version of the artifact}.

You can add code to be run with the `request`,  before any *path operation* receives it.

And also after the `response` is generated, before returning it.

For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

{* ../../docs_src/middleware/tutorial001_py310.py hl[10,12:13] *}

### Target language

Translate to Portuguese (Português).

Language code: pt.

For instructions or titles in imperative, keep them in imperative, for example "Import FastAPI" to "Importe o FastAPI".

Keep existing translations as they are if the term is already translated.

 * requests. It also allows for the replacement of placeholders in URLs and
 * parameters with actual credentials.
 *
 * <p>Usage example:
 * <pre>
 * {@code
 * Map<String, String> params = new HashMap<>();
 * params.put("token_url", "http://example.com/token");
 * params.put("login_url", "http://example.com/login");
 * Hc5FormScheme formScheme = new Hc5FormScheme(params);
 * formScheme.authenticate(credentials, executor);
 * }
