 * <p>This class uses (possibly repeated) invocations of {@link java.lang.System#gc()} to cause
 * finalization to happen. However, a call to {@code System.gc()} is specified to be no more than a
 * hint, so this technique may fail at the whim of the JDK implementation, for example if a user
 * specified the JVM flag {@code -XX:+DisableExplicitGC}. But in practice, it works very well for
 * ordinary tests.

        SmbTreeHandleImpl handleWithNullLoc = new SmbTreeHandleImpl(null, freshConnection);
        assertNotNull(handleWithNullLoc);

        // But operations that use resourceLoc might fail
        // For example, send methods would likely throw NPE when trying to use the null resourceLoc

Aber wenn Sie einen Exceptionhandler registrieren, registrieren Sie ihn für Starlettes `HTTPException`.

Auf diese Weise wird Ihr Handler, wenn irgendein Teil von Starlettes internem Code, oder eine Starlette-Erweiterung, oder -Plugin eine Starlette-`HTTPException` auslöst, in der Lage sein, diese zu fangen und zu handhaben.

Para usar isso, declare uma lista de `bytes` ou `UploadFile`:

{* ../../docs_src/request_files/tutorial002_an_py39.py hl[10,15] *}

Você receberá, tal como declarado, uma `list` de `bytes` ou `UploadFile`.

/// note | Detalhes Técnicos

Você pode também pode usar `from starlette.responses import HTMLResponse`.

///

Dessa forma:

* Este código de status será retornado na resposta.
* Será documentado como tal no esquema OpenAPI (e, portanto, nas interfaces do usuário):
