## Prérequis { #requirements }

FastAPI repose sur les épaules de géants :

* [Starlette](https://www.starlette.dev/) pour les parties web.
* [Pydantic](https://docs.pydantic.dev/) pour les parties données.

## Installation { #installation }

Créez et activez un [environnement virtuel](https://fastapi.tiangolo.com/fr/virtual-environments/) puis installez FastAPI :

            if (strictMode && DANGEROUS_CHARS.matcher(component).find()) {
                throw new SmbException("Path component contains dangerous characters: " + component);
            }

            // Check for trailing spaces or periods (Windows doesn't handle well)
            if (component.endsWith(" ") || component.endsWith(".")) {
                throw new SmbException("Path component has trailing space or period: " + component);
            }

        assertTrue(result.startsWith("Allow "));
        // Hexdump.toHexString produces uppercase hex
        assertTrue(result.toLowerCase().contains("0x001200a9"));
        // ACE.toString() outputs "Direct    " with 4 spaces
        assertTrue(result.contains("Direct"));
        assertTrue(result.contains("This folder only"));
    }

    @Test
    @DisplayName("Test toString format for deny ACE")

        // Test with null groups
        user = new TestFessUser("testuser", new String[] {}, null, new String[] {});
        assertNull(user.getGroupNames());

        // Test with groups containing spaces
        groups = new String[] { "group one", "group two" };
        user = new TestFessUser("testuser", new String[] {}, groups, new String[] {});
        assertArrayEquals(groups, user.getGroupNames());
    }

    @Test

    public void test_add_whitespaceInName() {
        TestScriptEngine engine = new TestScriptEngine();
        scriptEngineFactory.add("  test  ", engine);

        // Should be stored with lowercase and original spaces
        ScriptEngine retrieved = scriptEngineFactory.getScriptEngine("  test  ");
        assertNotNull(retrieved);
        assertEquals(engine, retrieved);
    }

Insbesondere wenn die Anwendung auf **Kubernetes** läuft, werden Sie wahrscheinlich **keine** Worker verwenden wollen, und stattdessen **einen einzelnen Uvicorn-Prozess pro Container** ausführen wollen, aber ich werde Ihnen später in diesem Kapitel mehr darüber erzählen.

## Mehrere Worker { #multiple-workers }

Sie können mehrere Worker mit der `--workers`-Befehlszeilenoption starten:
