Zusammen mit Hug (da Hug auf Falcon basiert), einen `response`-Parameter in Funktionen zu deklarieren.

Obwohl er in FastAPI optional ist und hauptsächlich zum Festlegen von Headern, Cookies und alternativen Statuscodes verwendet wird.

   * leaking resources callers must [close the response body][ResponseBody] or the response.
   *
   * Note that transport-layer success (receiving a HTTP response code, headers and body) does not
   * necessarily indicate application-layer success: `response` may still indicate an unhappy HTTP
   * response code like 404 or 500.
   *

        // Then - response is created even with null config
        assertNotNull(response);
    }

    @Test
    @DisplayName("Should verify SMB2 header length constant usage")
    void testSmb2HeaderLengthUsage() {
        // Given
        Configuration mockConfig = mock(Configuration.class);

        @Override
        public int size() {
            return testSize;
        }

        @Override
        protected int writeHeaderWireFormat(byte[] dst, int dstIndex) {
            return 64; // Simulate header writing
        }

        @Override
        public int encode(byte[] dst, int dstIndex) {
            // We need to override the parent ServerMessageBlock2's encode

Wir werden nun eine einfache Abhängigkeit verwenden, um einen benutzerdefinierten `X-Token`-Header zu lesen:

{* ../../docs_src/bigger_applications/app_an_py310/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Tipp

Um dieses Beispiel zu vereinfachen, verwenden wir einen erfundenen Header.
